Dissemination of ‘real time’ meteorological information to domestic aviation community

Published

on

On July 3, 1971, during the first JVP insurgency, while I was working with the then Royal Ceylon Air Force (RCyAF), based at China Bay, in Trincomalee, I reported to the squadron early morning and was told by our Officer Commanding the No. 3 Maritime Squadron, Flt Lt Denzil Fernando, that I was assigned to fly as ‘Second Dickie’ to Sergeant-Pilot Tony (Tuan Mohamed Zachariah) Dole in a de Havilland Dove with serial (registration) CS 406. We were to go to Vavuniya to pick up the then Government Agent (GA), Neville Jayaweera, and take him to Ratmalana (RMA).

Our trip to Vavuniya was uneventful, except that the runway, unused for many years, had been cleared and secured by the Army, with soldiers standing at regular intervals along the full length of the runway. After the GA boarded the plane we got airborne and set course for Ratmalana. It was a bit cloudy when we started. Soon the clouds got heavier, and we had to fly through the clouds to maintain our course. Not long afterwards, the weather became worse, and turbulence in the clouds caused our eight-seater D.H. 104 Dove to shake like a leaf in the wind.

The twin-engine transport plane didn’t have Airborne Weather Radar (AWR) to avoid rain clouds. AWR works on the principle that the more turbulent a cloud, the greater the mass of water it will support. This will ‘bounce’ off radar signals emitted by the aircraft, and will be proportional to the cloud thickness, thereby providing an image of the turbulence, within the cloud mass, as indicated on a screen in the cockpit of the aircraft.

Without AWR, our only option was to reduce speed to make the ride as comfortable as possible for the GA (and us), not unlike when driving on a bumpy road, and then ‘eyeballing’ the weather and hoping for the best by avoiding the more intense rain clouds. The only weather forecast reports available to us were for China Bay and Ratmalana airports, but no information whatsoever on observed weather en route.

By now, flying in cloud, we had lost sight of the ground and were unsure of our position. We were avoiding clouds to the best of our ability. The vertical development of some of the clouds were in excess of 10,000 ft at some places. So we decided to go below the cloud base, which was fortunately higher than existing terrain, so we could maintain sight of ground or water to pinpoint our position. In aviation parlance, this is known as a ‘visual fix’ of position.

We also flew further west towards the coast to reduce the chances of rising terrain (hills). Soon we spotted, through the rain, the unmistakable coastline, of Kalpitiya and Puttalam, enabling us to positively establish our position. We then continued to follow the coastline at low leve,l to RMA, flying under the jet aircraft approach path at Bandaranaike International Airport (BIA), Katunayake, and towards Colombo.

The air traffic control towers at Katunayake and Ratmalana were also reporting heavy rain showers. We found a patch clear of cloud, south of the Ratmalana airport, over Bolgoda Lake, and began circling there. But Sgt. Dole had an ace up his sleeve. He told me that showers present under cloud cells usually come in waves that transit the airport, and the best bet was to wait and land between the showers that we could see well from our vantage point in the south.

Sure enough, as soon as one rain shower passed the airport, we were well positioned to turn in and land in relatively clear weather with only a slight drizzle, before the next downpour hit.

This was exactly 50 years ago. We didn’t have radio navigational aid, except the Non-Directional Beacons (NDBs) at China Bay, BIA and Ratmalana that operated on low to medium frequency and were affected by bad weather (thunderstorms) and thus rendered useless in our circumstances described here. In fact, the signals emitted by Radio Ceylon were sometimes stronger! In addition, there were two Very High Frequency (VHF) Omni Radio Range stations (VORs) at BIA and RMA, but our aircraft was not equipped with a receiver that could be used in conjunction with the VORs. They were meant for the ‘big aircraft’. Other countries had Distance Measuring Equipment (DME) associated with the VOR, but not Ceylon.

Therefore, pilots had to navigate by a process called ‘Dead Reckoning’, which involved estimated ground speed and time over known ground features (cities, rivers, roads, railway lines and buildings for example). ‘If you reckoned wrong you were dead!’ To add insult to injury, we didn’t have ‘real-time’ observed meteorological information available to us in terms of cloud base and intensity of rain to help us make informed decisions as to what route to follow.

Today, technology has improved worldwide in leaps and bounds. We have ‘smart’ cellular phones and tablets with Global Positioning Systems (GPS). We have capabilities of providing better facilities to domestic air traffic, consisting of landplanes, seaplanes and helicopters. For many years we have had a radar station positioned on Pidurutalagala, the highest point in the island. In fact, we can even monitor certain areas of South India.

Unfortunately, real-time meteorological information is still not available as Sri Lanka has not invested in a communications system capable of providing such information. More than 15 years ago, Singapore installed a radar system at Changi Airport that was capable of giving information to pilots on the intensity of rainfall relative to their airports. We are told that Sri Lanka’s Meteorological Department invested Rs.200 million, in 2013, on a Doppler radar system which, in their so-called ‘wisdom’, they wanted to site at Deniyaya. But it was never installed, and the equipment is now in storage in damaged condition after it went ‘down the pallang’ while being transported there!

Today, there are many free websites which provide highly accurate satellite-based weather forecast information at a click of a button. It is also available on ground to flight dispatchers. It is therefore sad to note that the weather forecasts, produced by our Meteorological Department (who should be playing a key role) are not used by the aviation community, almost certainly due to a lack of confidence on the part of pilots and aviation operations officers. It should also be noted that in Sri Lankan domestic aviation, along with the satellite weather forecasts, the actual observed weather, must go hand in hand. Even this is still not provided by the Met’ Department. I believe that this is a major lapse.

The following incident illustrates the stark reality of what the current situation is for domestic operators. A few days ago, a commercially important passenger (CIP) was flown to Anuradhapura by a domestic air charter company to attend celebrations commemorating the two-year anniversary in office of President Gotabaya Rajapaksa. The outbound flight to Anuradhapura was uneventful. For the return flight to RMA, the flight dispatcher based at Ratmalana had to plan the flight. While the general weather forecast was rain, standard practice relied on the observed actual en route weather by police stations on the way: at Galgamuwa, Nikaweratiya, Kuliyapitiya, Divulapitiya, Palavi, Chilaw, Wenappuwa and Negombo.

All these observers are local police personnel, not qualified aviation or meteorological professionals. Consequently, their very subjective ‘met reports’ are along the lines of “the sky is dark”, “it is about to rain”, “it is now drizzling” or “heavy showers”, from which the flight dispatcher has to form a mental picture of what the en route weather is. One wonders what the insurance implications would be if an accident occurs.

To continue, the hapless pilot at Anuradhapura, who was in touch with his dispatcher on his cellular phone before departure, had to evaluate the risks and make an informed decision. Like Sgt. Dole and I did 50 years ago, he had to get airborne and ‘play it by ear’, so to speak. So, having reached the western coastline, he followed it all the way to Ratmalana. As a matter of interest, I was able to follow the progress of this single-engine light aircraft through one of the free apps on my smartphone, via satellite. That is what prompted this article.

I regard it as an absolute shame that in the last 50 years the Colombo Met’ Department has been unable to provide useful ‘real-time’ meteorological observations to domestic air operations. Yet to satisfy the international aviation community in the gathering of weather data, they have observation stations at all of Sri Lanka’s international airports. But it is a case of thus far and no further. Scrutinising the Meteorological Department’s website will reveal that they have weather observation stations in Kankesanturai (KKS), Jaffna, Mullaitivu, Vavuniya, Mannar, Trincomalee, Anuradhapura, Mahailluppallama, Puttalam, Batticaloa, Kurunegala, Kandy, Nuwara-Eliya, Badulla, Diyatalawa, Pottuvil, Ratnapura, Katunayake, Ratmalana, Galle and Hambantota. These stations are connected to the World Weather Watch (WWW) through a Global Telecommunication Network (GTS). I do not know whether they are automatic as in other parts of the world, or require a qualified human observer.

The sad part is that this real-time information is not available to domestic aviation operators (of both fixed-wing aircraft and helicopters) who have to rely on amateurish police station observations and information. If the observed real-time weather is brought online with a good communications network comprising more observation stations established at all the other domestic airports, weather updates will enhance and synergize air safety in real-time.

I do not know who is responsible for this unacceptable state of affairs, but certainly the Civil Aviation Authority Sri Lanka (CAASL), Airports and Aviation Sri Lanka (AASL), the Sri Lanka Air Force (SLAF), and the ‘keepers’ of some of the domestic airports should coordinate with the Met’ Office and have real-time weather reports available for all domestic flights.

More recently it has been reported, in the local media that the Colombo Met’ Office and Japanese International Cooperation Agency (JICA) have signed an agreement for two more weather radar stations, to be sited at Puttalam and Pottuvil, to replace the one that never ‘got off the ground’ at Deniyaya. Will JICA be able to help in establishing automatic observation stations accessible to domestic aviators, to determine and report on such vital meteorological data as cloud base, intensity of rain, wind direction and speed, and temperature, as a fundamental component of good communication?

It is sad that the ‘end users’ are never consulted in important matters such as these.

Rebirth in Buddhism

Published

on

By Dr. Justice Chandradasa Nanayakkara

The question of what happens after death naturally arises in the mind of thoughtful people, as we do not know what lies beyond death, because no one has ever returned to the living to recount his experiences life after death. Almost every religion across the world has a defined belief on what happens when a person dies, yet the question is still widely debated and discussed without any finality being reached on the issue. Most of the religious teachers from the earliest times, have been unanimous in affirming that life continues beyond the grave, but they differ widely on the question of what form and in what manner the survival takes place. Nevertheless, mankind continues to believe in some form of survival after death.

Regarding the question of survival after death, thinkers have generally followed one of two philosophical concepts. That is to say annihilationism and eternalism (in Buddhist, ucchedavada and sassatavada). First view is held by nihilists who claim that there is no life after death. They hold the view with the disintegration of the physical body the personality ceases to exist. This view accords with materialistic philosophy, which refuses to accept knowledge of mental conditionality. Those who hold the second view think that there is an abiding entity which exists forever and individual personality persists after death in a recognizable form as an entity called soul, spirit or self. This belief in some form or another is the basis of all theistic religions.

If you stick to the first view and deny that there is no continuity of life after death there would not be no moral law and vipaka (actions and results) operating in the universe enunciated by Lord Buddha and there would be no object in practicing self-restraint or endeavoring to free ourselves of the craving thanha which brings suffering in its wake. The cardinal teachings of the Buddha such as path to nibbana, Four Noble Truths and the eightfold path would be rendered nugatory and meaningless if death is followed by complete extinction. Similarly, those who believe eternalism which presupposes that individual personality persists after death in the form of soul or self as an enduring personality by means of transmigration is also rejected by Buddhism. This view runs counter to the very essence of Buddhism which denies existence of soul. This is the teaching of anatta doctrine, which distinguishes buddhism from other religions and marks it out from all other religious concepts.

In view of the virtual impossibility of establishing the truth of survival after death through empirical methods, question arises what is the attitude of science to this important and abstruse question which has baffled the minds of many people. Although, it is not possible to posit ‘rebirth’ as a scientific fact many men of science are of the opinion that mental, moral and physical inequalities can be accounted for on no other hypothesis than ‘rebirth’ hypothesis.

The idea of a cycle of birth and ‘rebirth’ is part of the teachings of the Lord Buddha. For many Buddhists death is not seen as an end, but rather as a continuation. Buddhists believe a person goes from life to life and see it another part of their long journey through samsara.

Buddhists do not regard ‘rebirth’ as a mere theory but as fact verifiable by evidence and it forms a fundamental tenet in Buddhism along with the concept of karma. Therefore, two principles-kamma and ‘rebirth’ are fundamental to understanding the teachings of Buddha. Kamma and ‘rebirth’ go in arm in arm. According to Buddhism there is no life after death or life before birth independent of kamma. Kamma is an immutable law of cause and effect, and we cannot avoid its consequences. Where there is kamma there must be ‘rebirth’. Most experiences in our present life are the results of our previous actions. Our actions of body, speech and mind (volitional activities) rebound back to us either in the present life or in some future life. It is the karma that conditions ‘rebirth’, past kamma conditions the present birth, the present kamma in combination with past kamma conditions the future. The present is the offspring of the past, and becomes in turn the parent of the future. For Buddhist death is not complete annihilation of a being though that particular life span ended, the force which hitherto actuated it is not destroyed. After death the life flux of man continues ad infinitum as long as there is ignorance and craving. Man will be able to put an end his repeated series of births by realizing nibbana, the complete annihilation of all forms of craving (Narada Thera).

The Buddhist doctrine of ‘rebirth’ should be differentiated from the theory of reincarnation, which implies transmigration of a soul and its invariable ‘rebirth’, as it is enunciated in Hinduism.

In his book What the Buddha Taught, Walpola Rahula Thera posed the question “if we can understand that in this life we can continue without a permanent, unchanging substance like self or soul, why can’t we understand that those forces themselves can continue without a self or soul behind them after the non-functioning of the body? ‘When this physical body is no more capable of functioning, energies do not die with it, but continue to take some other shape or form, which we call another life… physical and mental energies which constitute the so called being have within themselves the power to take a new form, and grow gradually and gather force to the full: King Milinda questioning venerable Nagasena asked: “Venerable Nagasena, does ‘rebirth’ take place without anything transmigrating? Yes, O king, ‘rebirth’ takes place without anything transmigrating? “Give me illustration, venerable Sir. Suppose, O king, a man were to light a light from light pray, would the one light have passed over to the other light?” “Nay, indeed, Venerable Sir. “In exactly the same way, O king, does ‘rebirth’ take place without anything transmigrating.

In this connection, it should be mentioned the word ‘rebirth’ is not a satisfactory one, as it implies that there is something that after death takes on flesh again. It connotes transmigration of soul or other entity consequent to a death of a person. The Pali Word used in buddhism is arising or Phunabba.

As there is no soul or self in Buddhism, question arises if there is no soul or self what is there to be reborn. This has been most vexed question among many religious scholars. This has been a topic of debate for centuries. According to buddhism there is no enduring, substantial or independently existing entity that transmigrates from life to life instead there is simply an apparent continuity of momentary consciousness from one life time to the next that is imbued with impressions or traces (samskaras)of the actions one has committed in the past. For Buddhists everything is changing and nothing is permanent. So, when a person dies not he but his energies that shape him take a new form. New life is connected to previous life through kamma. There is rapid succession of thoughts throughout the life continuum.

The Buddha is our greatest authority on ‘rebirth. Therefore, for Buddhist no other evidence is necessary is prove ‘rebirth’.

On the very night of His enlightenment during the first watch, enlightenment, Buddhas mind travelled back through all of his unaccountable past lives. This was facilitated by the development of retro cognitive knowledge. Though his mind stretched back to countless eons he never saw a beginning to his past existence. He found no beginning and no end. He also saw all the beings in the universe being born, living dying and being reborn over and over again without end, all trapped in a web spun by their past actions. This process is the round of ‘rebirth’ known as samsara, which means wandering from life to life with no particular direction or purpose.

The Buddha before his enlightenment as bodhisattva was born in different forms of existence. As such Buddhist have a firm belief in many realms of existence, both above and below the human realm. Therefore, we can safely assume we all have lived through countless different lifetimes before being born in the world and our birth here as a human being is the result of predominantly good kamma we have committed in the past life. Those good kamma may have been done in many life times before, or more likely done in the previous life. Therefore, the quality of future births depends on the moral quality of our actions now.

In Dhammachackka Sutta too in his first discourse referring to second noble truth, Buddha declared this very craving is that leads to ‘rebirth’.

In ancient Greece philosophers like Empedocles and Pythagoras too taught the doctrine of ‘rebirth’ and Plato made it an important assumption in his philosophy, as pointed out by Ven Piyadassi Thera.

A Good Guide to the Omicron Variant

Published

on

By M.C.M. Iqbal, PhD

Despite the WHO adopting a neutral system to name the variants of the coronavirus that keep emerging (using letters of the Greek alphabet), the Omicron variant is associated with South Africa. The last variant of the virus to emerge was the Delta variant, which surfaced in December 2020, in India. There are two more letters between Delta and Omicron in the Greek alphabet that the WHO decided not to use. These are ‘Nu’ and ‘Xie’, which the WHO thought could be confused with ‘new’ while Xie is a common surname in China.

The Omicron variant is spreading in many countries. With the number of infected persons rising and another wave expected, many countries in Europe have imposed the usual methods to arrest the spread, with immediate lockdowns. However, scientists are still collecting data to find out how bad Omicron is, since the data seems to indicate that in South Africa, the disease is not as bad as the Delta variant. At the same time, in Europe, there is no significant change in the number of persons hospitalized. Of immediate concern to health authorities are, is the Omicron variant spreading faster than the earlier variants, does it cause more or less severe disease, and can it bypass the vaccines available?

Discovery

Scientists in South Africa announced on 25 November the discovery of a new variant of the coronavirus. On 26 November, the WHO named it Omicron. Although South Africa has been labeled as the country of origin, the virus was identified in neighbouring Botswana. In addition, there are reports of an earlier detection of this variant in the Netherlands.

PCR tests look for four markers on the virus genome to identify it as the coronavirus. The tests in Botswana showed a reduced sensitivity because one of the four targets was not being detected. These samples were sent to South Africa, where scientists have state-of-the-art facilities to look for changes in the genome of the virus. Changes are found by reading the ‘letters’ of the virus genome (called sequencing) and comparing it to the already available genome of the virus. The new Omicron variant had many more changes than the Delta variant.

Global status

By 14th January, the Omicron variant had spread to 116 countries in all six continents since its discovery on 26 November 2021. The figure below shows the gradual replacement of the presently dominant Delta variant by the Omicron variant; at present global data on the coronavirus, maintained by Nextstrain (https:// nextstrain.org/ncov/open/global) shows a decline of the Delta variant from 88% on 30th October 2021 to 42% on 8th January 2022, while correspondingly the Omicron variant has increased from less than 1% to 56%. Nextstrain is a global database presenting a real-time view of the evolution of the genomes of the coronavirus and other globally important pathogens. The interactive platform provides information to professionals and the public to understand the spread and evolution of pathogens, including information on individual countries.

What’s unique about Omicron?

Unlike the previous variants of the coronavirus, this variant has over 30 changes (mutations) to its spike (a protein), the characteristic flower-like protrusion on its surface. It was these changes to the spike, one of the four targets of the PCR test that raised alarm bells in Botswana. This spike makes the coronavirus special – it is the key it uses to gain entry into the cells in our throat and lungs. The previous variants, Alpha and Delta also had changes in their spike protein, enabling them to enter cells more efficiently and thus making them more infectious. The vaccines against the virus are based on this spike, and the antibodies produced by our immune system are specific to the spike protein. Thus, any significant changes to the spike means the previous vaccines may not be effective against the newly changed spikes on the Omicron variant.

While the Omicron variant can spread rapidly, it appears to cause milder disease compared to the Alpha and Delta variants. Scientists believe this is because Omicron infects the upper airways or the throat, and not the lungs further down. Based on experiments done on hamsters and mice, scientists found the concentration of the virus was much lower in the lungs than in their throat. The earlier variants of the coronavirus caused severe damage to the lungs of the infected people, with extreme cases needing oxygen. This does not seem to be the case with Omicron. Scientists believe the changes to the spike enables the virus to enter cells in the throat more easily than in the lungs.

It can spread rapidly

The virus is quickly expelled into the air if it infects and multiplies in the throat. Since it causes a milder form of the disease, infected persons may be unaware that they carry the virus. They would be moving about socially and at work, spreading the virus. Thus, the obvious means of slowing or preventing the spread of the virus is to strictly wear the mask at all times, and avoid social gatherings.

Studies have suggested that the period between exposure to the virus and onset of symptoms has also reduced to three days for Omicron. At the pandemic’s beginning, this was more than five days, and for the Delta variant it was four days.

What is of immediate concern?

Of concern to scientists is the better ability of the Omicron to spread rapidly in the population and its suspected ability to bypass our immune system. Our immune system is our internal defense system, using antibodies and an arsenal of chemicals and cells. The available vaccines are designed on the coronavirus variants circulating in the population. Thus, major changes to the coronavirus can reduce the efficiency of the available vaccines. Both these concerns have been observed in the past month: Omicron can spread more rapidly than the presently dominant Delta variant, and observations on vaccinated people show a reduced ability by the vaccines to prevent infections, compared to the Delta variant. This has called for booster doses for people who have already received the two mandatory doses. In Israel, even a fourth vaccination is being administered.

How could the variant have evolved?

Variants of the coronavirus result from changes to the virus’s genome, called mutations. What is troubling about the Omicron variant is that it has many mutations in its spike. Mutations happen spontaneously as the virus multiplies in our bodies and spreads to others. Thus, the virus gradually accumulates small changes to its advantage. These advantages are infecting us more efficiently, spreading to others more easily, and multiplying more rapidly. Scientists believe that one possibility is that the virus circulated in a small isolated group of people (say a village), piling up the mutations over time, and then escaping into a broader population, and then eventually crossing borders.

Another possibility is that it developed in a single individual and spread to others. This happens when a person has low immunity, resulting in a prolonged infection because the immune system cannot eliminate the virus. This leads to the virus developing changes (mutating) to overcome the mild immune response. Answering this question needs scientists to painstakingly reconstruct the history of the virus, using tools from molecular biology. Unfortunately, locating patient zero is difficult since it is impossible to analyze the virus (or sequence its genome) of all the persons infected with the Omicron variant. What is usually possible is to determine a general area or community and the time of origin.

What can we do about it?

Vaccinate! This is the primary tool we have to prevent the spread of the virus and not give it opportunities to multiply. In addition, we should rigorously follow the simple rules we are familiar with – wear the mask when outside, physically distance ourselves, and follow hygienic practices by washing our hands with soap, and avoiding touching our nose and face with possibly contaminated hands.

The good news

The coronavirus has been with us for over two years. Many were infected and have recovered from the virus during this period, providing natural immunity. Others have acquired immunity through vaccinations. When a new variant infects these people, they will manifest a milder form of the disease. This may explain the reduced hospitalisation of Omicron patients.

A booster dose to those already vaccinated or were naturally infected by the coronavirus, appears to provide reasonable protection against the Omicron variant.

And the bad news

The Omicron variant can evade immunity from previous infections. A recent analysis of surveillance data from South Africa, involving over two million persons, indicated suspected reinfections of those previously infected. This is in contrast to Beta and Delta variants, which did not lead to reinfections on such a scale.

The Future

The coronavirus is here for the long haul. Variants will keep emerging, and it seems unlikely it can be eradicated. The media should help counter vaccine hesitancy and the spread of misinformation. As individuals, we need to understand the biology of the virus to avoid spreading the virus and infecting ourselves and others. Science has to be supported in a broad sense to develop strategies by the health authorities and policymakers.

The taste of freedom

Published

on

by Bhikkhu Bodhi

(Courtesy Access to Insight – BCBS Edition)

The clarion call of our present age is, without doubt, the call for freedom. Perhaps at no time in the past history of mankind so much as at present has the cry for freedom sounded so widely and so urgently, perhaps never before has it penetrated so deeply into the fabric of human existence.

In response to man’s quest for freedom, far-reaching changes have been wrought in almost every sphere of his activity — political, social, cultural and religious. The vast empires which once sprawled over the earth, engulfing like huge mythical sea-monsters the continents in their grasp, have crumbled away and disintegrated, as the peoples over whom they reigned have risen up to repossess their native lands — in the name of independence, liberty and self-rule.

Old political forms such as monarchy and oligarchy have given way to democracy — government by the people — because every man demands the right to contribute his voice to the direction of his collective life. Long-standing social institutions which kept man enthralled since before the dawn of history — slavery, serfdom, the caste-system — have now disappeared, or are rapidly disappearing, while accounts of liberation movements of one sort or another daily deck the headlines of our newspapers and crowd the pages of our popular journals.

The arts, too, bear testimony to this quest for greater freedom: free verse in poetry, abstract expression in painting, and atonal composition in music, are just a few of the innovations which have toppled restrictive traditional structures to give the artist open space in his drive for self-expression. Even religion has not been able to claim immunity from this expanding frontier of liberation. No longer can systems of belief and codes of conduct justify themselves, as in the past, on the grounds that they are commanded by God, sanctified by scripture, or prescribed by the priesthood. They must now be prepared to stand out in the open, shorn of their veils of sanctity, exposed to the critical thrust of the contemporary thinker who assumes himself the right to free inquiry and takes his own reason and experience for his court of final appeal. Freedom of speech, freedom of the press, and freedom of action have become the watchwords of our public life, freedom of thought and freedom of conscience the watchwords of our private life. In any form in which it obtains, freedom is guarded as our most precious possession, more valuable than life itself. “Give me liberty or give me death,” an American patriot exclaimed two hundred years ago. The succeeding centuries have echoed his demand.

As though in response to mankind’s call for wider frontiers of freedom, the Buddha offers to the world His Teaching, the Dhamma, as a pathway to liberation as applicable today as it was when first proclaimed twenty-five centuries ago.

“Just as in the great ocean there is but one taste — the taste of salt — so in this Doctrine and Discipline (dhammavinaya) there is but one taste — the taste of freedom”: with these words the Buddha vouches for the emancipating quality of His doctrine.

Whether one samples water taken from the surface of the ocean, or from its middling region, or from its depths, the taste of the water is in every case the same — the taste of salt. And again, whether one drinks but a thimble-full of ocean water, or a glass-full, or a bucket-full, the same salty taste is present throughout. Analogously with the Buddha’s Teaching, a single flavor — the flavor of freedom (vimuttirasa) — pervades the entire Doctrine and Discipline, from its beginning to its end, from its gentle surface to its unfathomable depths. Whether one samples the Dhamma at its more elementary level — in the practice of generosity and moral discipline, in acts of devotion and piety, in conduct governed by reverence, courtesy, and loving-kindness; or at its intermediate level — in the taintless supramundane knowledge and deliverance realized by the liberated saint, in every case the taste is the same — the taste of freedom.

If one practices the Dhamma to a limited extent, leading a house-hold life in accordance with righteous principles, then one experiences in return a limited measure of freedom; if one practices the Dhamma to a fuller extent, going forth into the homeless state of monkhood, dwelling in seclusion adorned with the virtues of a recluse, contemplating the rise and fall of all conditioned things, then one experiences a fuller measure of freedom; and if one practices the Dhamma to its consummation, realising in this present life the goal of final deliverance, then one experiences a freedom that is measureless.

At every level the flavor of the Teaching is of a single nature, the flavor of freedom. It is only the degree to which this flavor is enjoyed that differs, and the difference in degree is precisely proportional to the extent of one’s practice. Practice a little Dhamma and one reaps a little freedom, practice abundant Dhamma and one reaps abundant freedom. The Dhamma brings its own reward of freedom, always with the exactness of scientific law.

Since the Dhamma proposes to provide a freedom as complete and perfect as any the modern world might envisage, a fundamental congruence appears to obtain between man’s aspiration for expanding horizons of liberty and the possibilities he might realize through the practice of the Buddha’s teaching. Nevertheless, despite this concordance of ends, when our contemporaries first encounter the Dhamma they often find themselves confronted at the outset by one particular feature which, clashing with their familiar modes of thought, strikes them intellectually as a contradiction and emotionally as a stumbling block. This is the fact that while the Dhamma purports to be a pathway to liberation, a Teaching pervaded throughout by ‘the taste of freedom,’ it yet requires from its followers the practice of a regimen that seems the very antithesis of freedom — a regimen built upon discipline, restraint, and self-control. “On the one hand we seek freedom,” our contemporaries object, “and on the other we are told that to reach this freedom our deeds, words, and thoughts must be curbed and controlled.” What are we to make of this astonishing thesis the Buddha’s Teaching appears to advance: that to achieve freedom, freedom must be curtailed? Can freedom as an end really be achieved by means that involve the very denial of freedom?

The solution to this seeming paradox lies in the distinction between two kinds of freedom — between freedom as license and freedom as spiritual autonomy. Contemporary man, for the most part, identifies freedom with license. For him, freedom means the license to pursue undisturbed his impulses, passions and whims. To be free, he believes, he must be at liberty to do whatever he wants, to say whatever he wants and to think whatever he wants. Every restriction laid upon this license he sees as an encroachment upon his freedom; hence a practical regimen calling for restraint of deed, word, and thought, for discipline and self-control, strikes him as a form of bondage. But the freedom spoken of in the Buddha’s Teaching is not the same as license. The freedom to which the Buddha points is spiritual freedom — an inward autonomy of the mind which follows upon the destruction of the defilements, manifests itself in an emancipation from the mold of impulsive and compulsive patterns of behavior, and culminates in final deliverance from samsara, the round of repeated birth and death.

In contrast to license, spiritual freedom cannot be acquired by external means. It can only be attained inwardly, through a course of training requiring the renunciation of passion and impulse in the interest of a higher end.

The spiritual autonomy that emerges from this struggle is the ultimate triumph over all confinement and self-limitation; but the victory can never be achieved without conforming to the requirements of the contest — requirements that include restraint, control, discipline and, as the final price, the surrender of self-assertive desire.

In order to bring this notion of freedom into clearer focus, let us approach it via its opposite condition, the state of bondage, and begin by considering a case of extreme physical confinement. Suppose there is a man locked away in a prison, in a cell with dense stone walls and sturdy steel bars. He is tied to a chair — his wrists bound together by rope behind his back, his feet locked in shackles, his eyes covered by a blindfold and his mouth by a gag. Suppose that one day the rope is unfastened, the shackles loosened, the blindfold and gag removed. Now the man is at liberty to move about the cell, to stretch his limbs, to speak, and to see. But though at first he might imagine that he is free, it would not take him long to realize that true freedom is still as distant as the clear blue sky beyond the stoned and steel bars of his cell.

But suppose, next, that we release the man from prison, set him up as a middle-class householder, and restore to him his full body of rights as a citizen of the state. Now he can enjoy the social and political freedom he lacked as a prisoner; he can vote, work, and travel as he likes, can even hold public office. But there still remains — in the form of his responsibilities, his burden of duties, his limitations of power, pleasure, and prestige — a painful discrepancy between the freedom of mastery for which he might personally yearn, and the actuality of the situation which circumstances has doled out to him as his drearisome lot. So let us, as a further step, lift our man up from this middle-class routine, and install him, to his pleasant surprise upon the throne of a world monarch, a universal emperor exercising sovereignty over all the earth. Let us place him in a magnificent palace, surrounded by a hundred wives more beautiful than lotus-flowers, possessed of limitless resources of gold, land, and gems, endowed with the most sublime pleasures of the five senses. All power is his, all enjoyment, fame, glory, and wealth. He needs only express his will for it to be taken as command, need only utter a wish for it to be translated into deed. No obstruction to his freedom of license remains. But still the question stands: is he truly free? Let us consider the issue at a deeper level.

Three kinds of feelings have been pointed out by the Buddha: pleasant feeling, painful feeling, and neutral feeling, i.e., feeling which is neither pleasant nor painful. These three classes exhaust the totality of feeling, and one feeling of one class must be present on any given occasion of experience. Again, three mental factors have been singled out by the Buddha as the subjective counterparts of the three classes of feeling and described by him as anusaya, latent tendencies which have been lying dormant in the subconscious mental continua of sentient beings since beginningless time, always ready to crop up into a state of manifestation when an appropriate stimulus is encountered, and to subside again into the state of dormancy when the impact of the stimulus has worn off.

These three mental factors are lust (raga), repugnance (patigha), and ignorance (avijja), psychological equivalents of the unwholesome roots of greed (lobha), hatred (dosa), and delusion (moha). When a worldling, with a mind untrained in the higher course of mental discipline taught by the Buddha, experiences a pleasant feeling, then the latent tendency to lust springs up in response — a desire to possess and enjoy the object serving as stimulus for the pleasant feeling. When a worldling experiences a painful feeling, then the latent tendency to repugnance comes into play, an aversion toward the cause of the pain. And when a worldling experiences a neutral feeling, then the latent tendency to ignorance — present but recessive on occasions of lust and aversion — rises to prominence, shrouding the worldling’s consciousness in a cloak of dull apathy.

On whatever occasion the three latent tendencies to lust, repugnance, and ignorance are provoked by their corresponding feelings from their dormant condition into a state of activity, if a man does not make an effort to dispel them, does not strive to restrain, remove, and abandon them and bring them to nought, then they will persist in consciousness. If, as they persist in consciousness, he repeatedly yields to them, endorses them, and continues to cling to them, they will gather momentum, come to growth, and like a ball of flame flung upon a haystack, flare up from their initial phase as feeble impulses into powerful obsessions which usurp from a man his capacity for self-control. Then, even if a man be, like our hypothetical subject, an emperor over the earth, he is inwardly no longer his own master but a servant at the bidding of his own defilements of mind.

Under the dominance of lust, he is drawn to the pleasant, under the dominance of hate he is repelled by the painful, under the dominance of delusion he is confused by the neutral. He is bent up by happiness, bent down by sorrow, elated by gain, honor, and praise, dejected by loss, dishonor, and blame. Even though he perceives that a particular course of action can lead only to his harm, he is powerless to avoid it; even though he knows that an alternative course of action is clearly to his advantage, he is unable to pursue it. Swept on by the current of unabandoned defilements, he is driven from existence to existence through the ocean of samsara, with its waves of birth and death, its whirlpools of misery and despair. Outwardly, he may be a ruler over all the world, but in the court of consciousness he is still a prisoner. In terms of license he may be completely free, but in terms of spiritual autonomy he remains a victim of bondage in its most desperate form: bondage to the workings of a defiled mind.

Spiritual freedom, as the opposite of this condition of bondage, must therefore mean freedom from lust, hatred, and delusion. When lust, hatred, and delusion are abandoned in a man, cut off at the root so that they no longer remain even in latent form, then a man finds for himself a seat of autonomy from which he can never be dethroned, a position of mastery from which he can never be shaken. Even though he be a mendicant gathering his alms from house to house, he is still a king; even though he be locked behind bars of steel, he is inwardly free. He is now sovereign over his own mind, and as such over the whole universe; for nothing in the universe can take from him that deliverance of heart which is his inalienable possession. He dwells in the world among the things of the world, yet stands in perfect poise above the world’s ebb and flow. If pleasant objects come within range of his perception he does not yearn for them, if painful objects come into range he does not recoil from them. He looks upon both with equanimity and notes their rise and fall. Toward the pairs of opposites which keep the world in rotation he is without concern, the cycle of attraction and repulsion he has broken at its base. A lump of gold and a lump of clay are to his eyes the same; praise and scorn are to his ears empty sounds. He abides in the freedom he has won through long and disciplined effort. He is free from suffering, for with the defilements uprooted no more can sorrow or grief fall upon his heart; there remains only that perfect bliss unsullied by any trace of craving.

He is free from fear, from the chill of anxiety which even kings know in their palaces, protected by bodyguards inside and out. And he is free from disease, from the sickness of the passions vexing and feverish that tie the mind in knots, from the sickness of samsara with its rounds of defilement, action, and result. He passes his days in peace, pervading the world with a mind of boundless compassion, enjoying the bliss of emancipation, or teaching fellow way-farers the path he himself has followed to the goal, in the calm certain knowledge that for him the beginningless trail of repeated births and deaths has been brought to a close, that he has reached the pinnacle of holiness and effected the cessation of all future becoming.

In its fullness, the freedom to which the Buddha points as the goal of His Teaching can only be enjoyed by him who has made the realization of the goal a matter of his own living experience. But just as salt lends its taste to whatever food it is used to season, so does the taste of freedom pervade the entire range of the Doctrine and Discipline proclaimed by the Buddha, its beginning, its middle, and its end. Whatever our degree of progress may be in the practice of the Dhamma, to that extent may the taste of freedom be enjoyed. It must always be borne in mind, however, that true freedom — the inward autonomy of the mind — does not descend as a gift of grace. It can only be won by the practice of the path to freedom, the Noble Eightfold Path.
