The lane down Nugegoda which is in the outskirts of Colombo, is named Mudaliar Avenue. Two left turns after that would bring you to number 1/8. This is Uncle Siri and Aunty Olga’s domain. Sadly, she passed away. As Uncle Siri says, “she went to heaven in 2021”, a sentiment whispered softly sounding more like a person finding it impossible to fill the huge empty space she left. Perhaps painful heartstrings may be tugging when he mentions her. Sixty eight years is a very long time to share a blissfully happy life and lose your soul partner.Now Lionel Sirimane is alone.

He is 103 years old and is a classic example for those of us who have gone beyond 75 and are pre-occupied contemplating when the bell will knell for us. Let’s take a look at this wonderful man who greets every day that dawns with a positive awakening and makes the best of it. He is on Facebook, a real fast bunny with emails and up to date with aviation technology and is well aware of what is happening in our planet. On a sunny day you would see him mowing his lawn and he scoots out driving his Suzuki to Keell’s Supermarket to buy knick-knacks and groceries. Not bad at all Uncle Siri, you do show junior oldies like me how to count our blessings.

Uncle Siri was born on January 31, in 1920 in Kurunegala and studied at the Catholic College in Kotahena. He completed his SSC and left school join the Technical College in, Colombo and learned shorthand and typewriting and got employed as a typist.

That was the beginning, common to most of the young of that era. He then applied to the Fleet Air Arm was selected to the an aviation related trade. In 1942 he was sent to RNAS school (Royal Navy Air Service) in Maharagama which was called ‘HMS Bherunda’. It was a four-month course and Uncle Siri passed out of that institution as an aircraft electrician.

There were many young men entering aviation who had their baptism in Maharagama, and they were mainly riggers, electricians and fitters. And so started Lionel Sirimanne’s career in aviation which lasted 36 years in multiple roles that were connected to aeroplanes.

His first posting in Fleet Air Arm was at the Katukurunda Airport where some Italian prisoners of war had concreted the temporary metallic runway to a length of 3,300 feet. At this time the Katukurunda airfield was operating as a Royal Air Force base named ‘Ukussa’ with a reasonably equipped aeronautical repair center.

RAF pilots, engineers and WRENS were all billeted in different huts in the vicinity and so were the mechanics.

Electrician Sirimanne started working on aeroplanes specializing in electrical systems and radio transmitters. They had all types of war kites that came to this airfield, some on regular operations and some for repairs. The types they treated at Katukurunda at times were rather way past their prime such as Swordfish, Barracuda dive bombers rigged with torpedoes, Fairly Fulmars and Sea-Fire Fighters etc.

The work consisted of checking serviceability, repairs and modifications on aircraft brought to the single large hangar.

“Wiring in those aircraft were rather primitive circuits for landing gear, bomb release and Megger tests on circuits” says Uncle Siri. “The most important part was always the condition of the batteries,” he emphasizes to me giving me a 103-year-old smile with a ‘you see’ nod of his head.

Subsequently more modern aeroplanes too came to Katukurunda such as Grumman Martlets, Corsair fighters and Hellcats. Uncle Siri worked on them all. He was a master-craftsman comfortable with all types of electrical malfunctions in an airplane. The boy from Kurunegala had learned a valuable trade related to aeroplanes.

By this time the war ended and the participants, the winners and the losers both breathed a huge sigh of relief.

Lionel Sirimanne left Katukurunda and found employment in the radio section of the Department of Post and Telegraph. From there, he was sent to the Ratmalana Airport to repair communication facilities and navigational aids at the aerodrome.”I came to know the first Air Traffic Controller, Mr Maurice Jansz and he advised me to learn Morse Code and get a PMG’s License to operate radio communications.

He was a kind man who later became my good friend. There was talk of a new national airline being formed and the word was out that they will be needing pilots, engineers and flight radio officers. Sirimanne hastened to learn his da da da and di di da di (- – – and ..-.) codes of the alphabet and passed his exams to become a radio officer. In 1947, Uncle Siri joined Air Ceylon as a flight radio officer and worked on charter flights.

His major break came when Air Ceylon undertook to do a Colombo to Sydney flight manned by a full Ceylonese crew. Lionel Sirimanne was slotted as the second radio officer under the senior Head of Communications, Mr John Vedavanam, a very kind professional gentleman who I too had the privilege of knowing personally when I was a fledgling pilot.

Air Ceylon flew its first commercial flight to Jaffna and onwards to Madras on December 10, 1947. In the 40s commercial aviation in Asia was at its infancy. The navigational facilities were at best mediocre, and their reliability was at most times questionable. The pilots communicated with aerodromes on VHF which may have had a possible maximum range of 200 miles at best.

The rest of the communication was on HF which had extended range but was not easy to operate. The flight radio officer is the one who handled all the extended communications and assisted in map reading and dead reckoning aircraft positions in navigation.

In the early 50s the Muslim community in Ceylon chartered a DC-3 from the national carrier to fly them to Jeddah for their annual pilgrimage to Mecca. The company did not have charts to fly this unknown route. They had very capable crews but certainly were lacking in the ‘know-how’ of flying in the isolated skies over rugged desert land.

The RAF pilots operating out of Katunayake were well versed in long-range flying and they had all the charts covering Asia and the Middle East. Air Ceylon picked a capable crew and sent them to Katunayake to obtain all the charts pertaining to the journey and they were given a thorough briefing for the route by the RAF. The plan was to fly from Ratmalana to Bombay and then to Karachi and do a ‘night-stop’.

The next day they were to fly to Salala in Oman as a pit stop to refuel and then fly on to Aden for another night-stop. The final leg was to fly along the Red Sea to Jeddah. From there the pilgrims would travel by road transport to Mecca. The crew was Capt Peter Fernando, Capt Emil Jayawardena, Flight Engineer G V Perera and Radio Officer Lionel Sirimanne.

“Flying from Karachi to Salala we faced a very dangerous situation” Uncle Siri explained. “Salala was completely covered with clouds, eight Octas of it and we could not descend as the visibility would be zero once we get into the cloud layer. There were mountains surrounding the airfield. The worst was, the airport radio beacon the only landing aid was not working and so also the communication equipment,” he sighed and continued. “It was a total dead end, nothing to see except clouds and no communication and no radio beacon to guide us to the airport.

But the pilots were very clever. They were both ‘seat of the pants’ flyers with excellent situational awareness. The airport was by the coast and east of that was the Arabian Sea. We flew eastwards till we were sure we were over the water and descended through the cloud till we saw the sea and a fishing boat. We were below 1,000 feet by then. We turned 180 degrees and backtracked the way we came. Just then the radio beacon came alive pointing to where the airport was, and the VHF radio started working. We managed to land safely in Salala,” explained Uncle Siri.

“The signal of the DC-3 arrival had not reached the Salala Airport and the RAF staff manning the airfield had closed the airport and gone for a sea bath as they were not expecting any aircraft to land in Salala that day. They were enjoying the beach and the Arabian Sea when they heard an aircraft circling the cloud covered sky and realized someone was trying to land in Salala. They ran and got into their vehicle and drove as fast as they could to the airport and switched on the communications and the navigational equipment.

“We refueled and were ready to depart and the RAF staff gifted us two cases of beer for the serious mistake they made closing the airport. The rest of the trip to Aden and Jeddah and the return flight was uneventful.”

The pilot in me always wondered how these ancient Mohicans flew their magnificent old aeroplanes with such limited technology and survived the sky? They carved the path for us to follow, and the aviation fraternity owes them at least the remembrance.

Back to Uncle Siri. In 1954 he got married to Olga de Silva who was a flight stewardess with Air Ceylon. She had joined the company in the first batch of cabin crew recruited by the national airline. Uncle Siri and Aunty Olga had an exceptionally wonderful marriage and raised two sons and a daughter, Sunil, Laksen and Minoli who always adored their parents.

I had met the senior Sirimannes when I was young and re-connected with them again in 2012 when I was writing the 100-year-old history of aviation in Sri Lanka. Uncle Siri was hale and hearty, but Aunty Olga was wheelchair bound. My wife and I at times visited them and shared a few lunches with palatable conversation. Of course, the subject was always aeroplanes and the people who flew them in bygone years. They knew stories that we loved to hear as they both had flown as fellow crew members with my father who was a DC-3 Captain.

The year 1955 was a new chapter for Mr Sirimanne. He was seconded to KLM along with a few others to work as flight crew. He started as a radio officer and operated on DC-4, DC-6, DC-7, Lockheed Constellations and Electras. The routes covered the whole world. The ‘Flying Dutchman’ flew everywhere. Aviation communication and en route Air Traffic Control steadily became more sophisticated and the Radio Officers became redundant Internationally.

Uncle Siri shifted seats and became a Flight Navigator sponsored by KLM. A whole new world of Astro Navigation opened to him. It is a poetic art of calculating an aircraft’s position by measuring the elevation of a star and its azimuth and using an almanac to draw a possible location. Mark St Helaya method was used for celestial navigation work. This was also how they navigated the sailing ships of the new world. Modified and improved versions came to aeroplanes and specialized navigators used their sextants to accurately plot aircraft positions.

This is what Navigator Sirimanne did from 1957 to 1961 flying mainly the Atlantic on KLM’s triple rudder Allison engine powered Super Constellations. He may have used popular navigational stars such as Aldebaran from Taurus, or Sirius from the leg of Orion and the ever-popular Altair to cross the Atlantic from Amsterdam to New York. The navigators picked their stars and pre calculated positions of the aircraft and waited for the calculated time to use the periscopic sextant and measure the stars.

The Lockheed Constellation flew around 18,000 ft and often the Atlantic sky was cloud laden leaving no possibility to see stars to make calculations. I too flew the same route crossing the Atlantic many times on Jumbo Jets. On such flights we pressed a few buttons and commanded the aeroplane to go to New York and back with pinpoint accuracy navigating from FMS (Flight Management System) equipment. We were blessed. Uncle Siri crossed the Atlantic looking perhaps at the same stars that Christopher Columbus used to navigate the Santa Maria.

The last of the original Mohicans Lionel Sirimanne

Three cheers to you Uncle Siri, I certainly envy you for that serene act of shooting stars with a sextant from an aeroplane.

The Navigator returned home after six years of flying with KLM. He was back in Air Ceylon and worked as an aircraft electrical engineer and moved to jets when the Trident 1E came into service in 1969. He also qualified to sign Qantas and BOAC planes that landed in Katunayake. Air Ceylon stopped operations in 1979 with the birth of Air Lanka and Uncle Siri said his fond farewell to aviation after 36 long years. He has had his moments and was left with memories of wonderful aeroplanes he flew with unforgettable crew members.

Lionel Sirimanne was a well experienced and efficient Flight Radio Officer. He found alternate employment to man the communications in ships and switched to being a sailing radio officer in the Merchant Navy. Sailor Sirimanne went all over the world traversing the popular sea routes and heading to ports in the Atlantic, the Mediterranean, the Black Sea, the Indian Ocean, almost all seas except the Pacific.

In 1986 he said good-bye to his working life, just so he could be home with his lovely wife Aunty Olga. Home was the aviator from the skies and home was the sailor from the seas. The children had flown the nest to pitch their tents in foreign lands and Uncle Siri and Aunty Olga settled in good old Sri Lanka to a well-deserved restful twilight.

“It is only at the going down of the sun one would know how beautiful the day has been.” The Sirimanne couple enjoyed their time together thanking the good lord that gifted them a beautiful life. I saw them in 2012, Uncle Siri was 92 and Aunty Olga a tad behind. True the sun was disappearing from the horizon but there was enough light still to paint in clear pastel colours the remainder of their lives.

The final ‘good-bye’ of Aunty Olga must have been extremely difficult for Uncle Siri to accept. But he still keeps on batting, loved and adored by his children and their friends. At 103, I do not think there is any friend of his vintage walking this planet. That must be sad, but he makes the best of it still, doing little household chores and pruning his white-leafed shoe flower plants in the yard.

He sure is an admirable example for the elderly, a man who has the wisdom of words to share with the younger generations on how precious life is and how lucky we are to count our blessings. Off and on he would meet another old pelican like me, and he still lights up bright when the conversation shifts to old aeroplanes and old pilots who flew them who are not with us anymore.

“Such is life” says Uncle Siri, the Face Book and email ‘fast bunny’ who drives his little Suzuki and mows his lawn on a sunny day.

Is power devolution under JVP-NPP a political daydream?

Published

on

Former President Chandrika Kumaratunga

The JVP General Secretary Tilvin Silva’s recent remarks at a news conference in Jaffna where he ruled out the possibility of holding provincial council elections this year has been widely reported and widely criticized. About the same time there was another media event in Jaffna that went largely unnoticed and unreported outside Jaffna. What was said at the second media event may carry far more political implications than Tilvin Silva’s election timing talk. A veteran Tamil political participant made the startling yet not implausible statement that the prospect of having political devolution under the JVP-NPP government is becoming “a daydream”. The statement was made by Dr. K. Vigneswaran, who served as Provincial Secretary to the only North-East Provincial Council Government that was elected under the auspices of the Thirteenth Amendment.

Dr. Vigneswaran is a Professional Civil Engineer who studied at Royal College, graduated with First Class Honours in Engineering in 1964, and went on to complete a pioneering PhD at the university of Waterloo, Canada, applying the finite element method (FEM) in the field of Geotechnical Engineering. His engineering career has always been at the Irrigation Department where he rose to a Deputy Director. That was when the department was in its golden years, and Vigneswaran was known for his technical mentorship, meticulous administrative skills, and for knowing the fine print of everything. While at the Irrigation Department, Vigneswaran married Ramya de Silva, a fellow irrigation Engineer. After 1983, Vigneswaran became a fulltime political activist and a powerful resource in Tamil politics, but with unwavering commitment to nonviolence, democracy and federalism. The family moved first to India and then Canada, and Vigneswaran has been shuttling between Canada and Sri Lanka.

Devolution: Tortuous Trajectory

Since 1987, the Indo-Sri Lanka Agreement, and the 13th Amendment, Vigneswaran has been a permanent fixture in all the politics and institutional dynamic of implementing 13A and establishing provincial councils. He served as Secretary to the only elected Provincial Government for the Northern and Eastern Provinces. After 1994 and the election of Chandrika Kumaratunga as President, Vigneswaran became a key participant in all the civil society efforts and government initiatives to restore the PCs and implement 13A, both during the Kumaratunga presidency and the succeeding administrations of Mahinda Rajapaksa and the Sirisena-Wickremesinghe duo.

Devolution efforts stalled after the election of Gotabaya Rajapaksa, who in so many words declared that he had no time for 13A or PCs in his presidential agenda, whatever it was. Only that his whole agenda turned out to be a wholesale disaster for the country. Already by then, all the nine Provincial Councils had fallen into abeyance with the cancellation of the 1988 PC elections by the Sirisena-Wickremesinghe duo, with the TNA standing by. The abeyance continues under the JVP-NPP government with no apparent end in sight after Tilvin de Silva’s statement in Jaffna.

I say all this to provide the proper context for Vigneswaran’s statement in Jaffna that the prospects for power devolution under the JVP-NPP government are becoming a political daydream. He said something else as well: that of all the government leaders he has encountered over the years, the only leader who has been genuinely sincere about power devolution is former President Chandrika Kumaratunga, and no one else. I am constrained to add that the insincere category would include Ranil Wickremesinghe, who for all his handsome promises, never matched any of them with experiential sincerity. The present JVP-NPP government still has time to show that they are not an insincere lot.

It is not my purpose to agree with or question Dr. Vigneswaran’s assertions, but to use them as cue and context to comment on the widening mismatch between the JVP-NPP government’s promises and its practices on the matter of power devolution and the restoration of the PC system. With a stalling economy, rising prices and external shocks, it is obvious that the government has all the economic matters to worry about, but that does not mean that it can ignore all the other government responsibilities. No government is put in power to solve a single problem or address a single issue. It is in the nature of governments to deal with multiple problems with varying priorities. Otherwise you could have a single cabinet minister to deal with one problem at a time. That is never going to be the case.

The economy is of course the top of mind priority for the government even as it is a top of mind concern for the people. Even on the economic front, the government is holding steady but is showing little progress. And there are other government initiatives where political accountability will call for answers: to wit, the catchall Clean Sri Lanka programme, ambitious educational reforms, contentious energy sector reforms and, yes, power devolution as well as the overpromised constitutional reforms. Not to mention the sprawling unforced errors over substandard coal imports, foreign exchange fraud, and the chronic neglect of developing the renewable energy sector. Correcting these fields of errors may require a separate ministry for each.

Devolution: Daydream or Deliverable

On the PC system and constitutional reform, there has been scant progress in spite of handsome promises. On both, the government is inadvertently deepening the holes that it had dug itself into through indifference, inaction or procrastination, or all of them and more. In the matter of devolution and provincial councils, the government can simply defuse the situation by directing the Election Commission to conduct elections at the earliest opportunity that is logistically possible. Making his statement in Jaffna, Mr. Tilvin Silva alluded to funding shortfall and legal complications as reasons for the necessity to postpone PC elections until next year. Neither reason holds water.

The funding question would seem to have been put to rest by the statement of Health Minister and Cabinet Spokesman Nalinda Jayatissa, presumably reflecting cabinet consensus, that there are no funding issues and if needed additional funds could be arranged through supplementary allocations. It is also disingenuous to cite legal complications as a reason. The so called legal complications arose because of the collective stupidity of the Sirisena-Wickremesinghe parliament that included the then miniscule NPP and the politically-lost TNA. The JVP-NPP has now ballooned from a handful MPs to a two-thirds majority and it can expedite any legislation that it wants to enable the PC elections to be held without delays.

Alternatively, the elections can be held under the old arrangement of proportional representation with assurance by political parties to honour their commitment to fielding more female candidates. Already at a gathering of all political parties, including the NPP (but not the JVP), and civil society groups, convened by People’s Action For Free & Fair Elections (PAFFREL), the political parties jointly committed to a 25% quota for women and youth under the old electoral system. The ongoing parliamentary committee exercise studying the legal matter, headed by the overstretched Foreign Minister Vijitha Herath, is also an unnecessary red herring. The Election Commission is ready to go under whatever law or electoral system that is before it. So, there is no reason to hide behind legal complications to further delay the PC elections.

Somewhat amusingly, Public and Parliamentary Affairs Minister Ananda Wijepala has trotted out the argument that the NPP government has already conducted two nationwide elections during the one and a half years it has been in office, and that unlike the Ranil Wickremesinghe government the JVP-NPP is not in the business “to delay elections for our personal benefit” – whatever that means. Unfortunately, the good minister is missing the point. The question is not how many elections can the JVP-NPP hold in how many years, but how many years do people in the provinces have to wait before they vote in another provincial election? How many more years? That really is the question.

We know the current situation in the provinces. There are provincial governments but no elected provincial councils. The government administration in every province is being run by the President of the Republic through his handpicked governors and unelected government officials. This is a travesty of democracy and the euthanizing of the PC system. Already under 13A, the office of the provincial governors has been constitutionally and legally compared to the office of the Governors of old Ceylon who represented the monarch in what was then a crown colony. The irony is that a JVP-NPP President may have inadvertently positioned himself as the monarch of all he provincially surveys, courtesy of the Thirteenth Amendment!

The JVP was in the forefront of the litigation that caused the demerger of the Northern and Eastern Provinces. If Dr. Vigneswaran’s assertion were to prove correct, a potential dissolution of the provincial system under the JVP-NPP government would be the consummation of the JVP’s original opposition to the introduction of the provincial council system itself. The whole system may not be eradicated, but it could be devoured of its democratic essence while preserving the administrative shell as the medium for the country’s president to overreach into the provinces. That would be worse than a daydream, a real nightmare.

Rewiring Brain: Meditation to Break the Cycle of Craving

Published

on

“Craving begets sorrow, craving begets fear. For him who is free from craving there is no sorrow; how can there be fear for him,” Dhammapada verse 216 states. The mental factor craving, Tanha in Pali, is central to Buddhist Teaching, as its ultimate goal is the cessation or extinction of it—tanhakkhaya. Even though Tanha is translated as craving here, it can sometimes mislead modern readers into thinking tanha only refers to extreme or physical addictions. Just as with any Pali term, it has broad meanings. Venerable Walpola Rahula describes it as “thirst” or unceasing wanting, one of the deep-rooted proclivities or latent tendencies (anusaya) of life (Rahula 1959), without which life as we know would not exist.

Even though the Buddha recognized this natural phenomenon two and a half millennia ago, it was only in the late 20th century that science took note of it and gave it a captivating term—the Hedonic Treadmill. The advantage of this empirical investigation to us Buddhists is that it provides a way to gain penetrative, experiential comprehension (anubodha) of this concept using the vernacular of this technology-savvy age—an alternative to struggling with the language of a bygone era.

These investigations have revealed that there are no hard-to-comprehend metaphysical or mysterious elements involved with this phenomenon; it is a biochemical process fundamental to sustaining life. What is more, an effort to grasp this concept would be well within the goals of Vipassana meditation described in the Sutta Pitaka, incorporating the four elements of investigation: body (kayanupassana), sensations (vedananupassana), mind (chittanupassana), and natural laws (dhammanupassana).

Vipassana and modern science

Vipassana meditation is an in-depth exploration of how humans perceive the world, gain knowledge, and interact with themselves and the environment. Knowing this with wisdom allows one to lead a harmonious way of life (samadhi), a condition conducive to curbing the “thirst” and achieving the Buddhist ideal. The goal of modern science is also to investigate life, but humanity has often used that knowledge to increase material wealth and comfort, providing only lip service to spirituality on the fringe.

An attitude that tends to ignore the consequences of wanting more and more – thirst, potentially endangering the planet. However, that does not prevent us from using scientific information as and aid or a tool to grasp Buddhist concepts. The scientific method bears parallels to the Buddhist approach: it is based on causality (paticcasamuppada), empirical verification (ehipassiko), systematic observation (meditation), and rejecting dogma and beliefs. The primary difference is simply the vocabulary used.

The process of perception: five aggregates

Our five external sense organs receive data (vedana) containing information on the environment: Eyes: receive light, Ears: receive sound, Skin: senses physical contact and temperature, Nose & Tongue: sense chemical properties of substances. The data received by the sense organs is transmitted to the brain, where it is registered as neural networks (sanna). Neural networks, which are interconnected groups of nerve cells (neurons) can be viewed as mind-readable QR codes.

The activity of the brain, or mind (mano), processes this data and converts them into actionable information (sankhara). Modern neuroscience and psychology have made great advances in understanding these processes at the molecular level. This process allows the individual to become aware of their environment, build an autobiographical memory or the notion of a self (atta), and take actions to protect and perpetuate life.

The Pali term vinnana refers to the collection of information committed to memory. Translating vinnana as “consciousness” can be confusing, as the latter often refers to all brain activities. All physical phenomena that sense organs encounter and the mental constructs (sankhara) are referred to as Rupa. This activity of mind forms the basis of all knowledge, representing the entire world as perceived by the individual. This process is what the Teaching refers to as the Five Aggregates (pancakkhanda). The critical takeaway is that the world we perceive is merely a mental construct. While an objective world exists, our sense organs have limitations in seeing it—a fact easily realized through the hundreds of illusions used for entertainment.

Evolution and emotion

The evolutionary purpose of this data processing mechanism is to enable living beings to respond to environmental factors for survival. The psychological and physiological state that arises prior to acting is called emotion. Primarily, emotions can be of three kinds: desire (loba) – seeing a new phone causes an urge to buy it, even though the current one works fine; aversion (dosha) – encountering a vicious dog triggers a “fight or flight” response; delusion (moha) or illusion – an unanswered message to a loved one triggers worry or speculation. Thus, tanha or thirst represents how we connect to the world in its entirety; it can be desire, aversion, and delusion, not merely simple greed. Consequently, these are natural phenomena beyond our immediate control, which are intended to sustain life. In other words, emotions are the forerunner to volitions or intentions, which the Teaching defines as kamma.

The biochemistry of craving

Emotions result from the interaction between the nervous system and biochemicals known as neurotransmitters and neuromodulators (e.g., dopamine, serotonin, epinephrine, GABA, glutamate, acetylcholine, and endorphins). Just as the Buddha’s simile of two bundles of bamboo supporting each other describes, these two processes are interdependent and co-arising. Every thought or emotional state corresponds to patterns of neural firing. When neurons fire, they release these chemicals into synapses, influencing how one feels and acts. This release perturbs the body’s normal balance, or homeostasis. Once an action is complete, these chemicals are reabsorbed, and the body returns to its baseline.

Return to baseline is essential for survival. For example, if we stay satisfied with just one meal forever, we could not sustain life. Nature has developed another mechanism to prevent us from being satisfied – we also habituate. In the case of dopamine, the brain adapts by reducing the response to the same stimulus. To get the same level of satisfaction with repeated experiences, the amounts of neurotransmitters needed keeps increasing. This leads to the cycle of craving and dissatisfaction—the Hedonic Treadmill. You “run” toward happiness on the treadmill, but it does not take you anywhere, leaving you in the same emotionally unsatisfactory state, wanting more and more.

Breaking the cycle

This explains why achievements and possessions do not bring permanent happiness, and lead to a cycle of struggle, addiction, crime, and other ills of society. For Buddhists, it also explains why we cling to meaningless rituals. The Dhamma captured this complex phenomenon in the Four Noble Truths: pleasant experiences are impermanent (anicca), leading to grasping (tanha) and unsatisfactoriness (dukkha). The remedy is the Eightfold Path that involves wisdom (panna), conduct (sila), and harmony (samadhi).

Neuroplasticity and the point of liberation

While we cannot stop the sense organs from receiving stimulation (vedana) and sending them to brain, the mind can be developed to prevent vedana from leading to tanha. This is the “point of liberation,” the seventh link in the paticcasamuppada formula. We may not have free will, but we have ‘Free Won’t’ or the ability to say no to the natural tendency to act upon stimuli. We can rewire our neural connections to do so. This ability can be cultivated by practice and repetition, and neuroscience refers to it as neuroplasticity—the brain’s ability to change with experience.

The natural tendency of the brain is to strengthen frequently used neural networks while weakening and eliminating lesser used networks and building new ones as needed. This is known as neural plasticity or rewiring the brain. As described in the Eight-fold Path, the way to weaken and eliminate dopamine-driven neural networks includes three aspects. First, the process leading to thirst must be understood. One must engage in sila – activities and thoughts that cultivate Metta: loving-kindness and goodwill, Karuna: compassion, Mudita: appreciative joy, and Upekkha: equanimity, emotional stability, calmness, and evenness of mind in the face of gain and loss, praise and blame, fame and disrepute, pleasure, and pain. That must be done with wisdom, ritualistic behavior does not strengthen the correct neural networks. These activities promote a “cocktail” of oxytocin, serotonin, and GABA, subduing the role of dopamine and helping us step off the Hedonic Treadmill. This leads to a tranquil state of mind and a harmonious existence – samadhi. Again, it is an interdependent, co-arising process that improves upon repetition. Using mind altering substances hijacks this process, thus the need for adhering to the Fifth Precept.

The goal of Vipassana is to understand this process and train the mind to say “no” to tanha. It is not just about sitting on a mat; it requires developing a lifestyle that maintains homeostasis or harmony, samadhi, at every moment. Pali term bhavana means the development of wisdom and insight. In modern vernacular – rewiring brain. This model must be assessed for its efficacy by the individual and realize the benefits by themselves –ehipassiko; knowledge without practice does not work. According to what the Buddha taught, that is the path to cessation or extinction of craving – tanhakkhaya, the supreme goal.
