First artificially inseminated foal in Sri Lankan

By Sajitha Prematunge and Lalantha Wanniarachchi

Tall and stout by Sri Lankan standards, Samantha, was quite oblivious to her historical significance. She is the first artificially inseminated foal in Sri Lanka. From the former Director of Forestry and Environment Division, Mahaweli Authority turned breeder, Palitha Samarakoon, who tried to get mare Thulvaan to conceive but in vain, to the veterinary team at Peradeniya University, Veterinary Science Faculty, the coming of the now happy and healthy filly was something akin to childbirth. Samantha was the culmination of years of hard work and months of anxious anticipation.

A casual conversation with Peradeniya University, Veterinary Science Faculty, Senior Lecturer Prof Basil Alexander convinced Samarakoon that artificially inseminating a mare was not altogether impossible. Ten doses of semen, of Arabian pedigree, were brought from a stud farm in California at Rs 100,000 each. Thulvaan of the seventh generation from Upali Wijewardene’s stock was the ideal candidate.

 

Veterinary marvel

The insemination was professionally carried out by Senior Lecturer Dr Dammika Perera together with Alexander and Anil Pushpakumara of the Veterinary Science Faculty. Of course, a straightforward artificial insemination, as that of Samantha’s, was probably a cake-walk for a Department that introduced to Sri Lanka, technologies such as embryo transplantation to create high standard cattle over a decade ago. While a cow gives birth to an average of eight to 10 calves during her lifetime, they have thousands of eggs in their ovaries. In a bid to utilise the maximum reproductive potential of genetically superior female animals with high milk production capacity, multiple embryos harvested from such cows were transferred to recipient cows to complete gestation.

“The technology allows us to get up to 200 calves from a cow that would have had only eight in its lifetime, under natural circumstances,” said Dr Dammika Perera. He explained that artificial insemination allowed the selection of superior paternal genetic material, but the embryo transfer technique facilitates selection of both superior maternal and paternal genetic material. “The technology can be further developed by splitting an embryo to get two calves,” said Perera. The faculty also devised a method with which live embryos could be stored in liquid nitrogen. “Having a ready supply of embryos allows farmers to time the births according to their milk production requirements and availability of resources such as grazing grounds.”

However, Dr. Perera explained that artificially inseminating a mare was a novel experience. “The mare has to be in heat for the egg to be fertilised. We had to prime the womb with hormone treatment for maximum effect,” Perera explained the process. “Then we had to make sure she was in fact in heat by looking for signs such as changes in the vaginal opening and passage.” According to Perera, cervical tone has to be monitored and hormone treatment continued till desired tone is achieved. Ultrasound scans of the uterus, examination of ovaries, regular scans to monitor egg diameter and further hormone treatment to bring eggs to the desired size are all a part of the artificial insemination process.

“It is only after ensuring that everything is satisfactory that we take the sperm out of cold storage, bring it down to room temperature and inseminate the mare.” This is followed by further hormone treatment and scans at 12-hour periods. “By the 15th day we can determine whether the mare has successfully conceived. Scans are done at the end of the first and second trimesters to monitor the growth of the foetus, identify any abnormalities and interventions to rectify such abnormalities, carried out.”

Dr. Perera is treading unfamiliar territory. Consequently, his job requires critical thinking and a certain amount of derring-do, as it were. He admitted that although veterinarians must be aware of all the state-of-the-art research in the field, foreign research was not directly applicable to a country like Sri Lanka due to geographical and climactic differences. “Some are economically not viable. Research can’t be undertaken lightly because that would lead to waste of valuable resources. It has to be targeted at finding what works for our country.”

The gestation period of a mare is 11 months and 15 days, give or take 15 days more, said Samarakoon. But Samantha, being of good pedigree, consequently quite well-developed, was a feisty one and Thulvaan was forced to deliver 15 days ahead of schedule.

 

Animal lover

Samarakoon became the proud owner of a cow on his seventh birthday, when his mother bought it for him from an auction at the Kundasale farm for Rs. 80. Thus began his love for animals. He later graduated to elephants and crocodiles, but it goes without saying that he had a soft spot for horses. Samarakoon joined the Mahaweli Authority in 1979. He believed that having hands on experience was vital for him to perform his duties as the Director of Forestry and Environment Division. Samarakoon was responsible for successfully completing a 12 million tree planting project, a feat not achieved by any department since. “But to this day no one has expressed interest in acquiring that knowledge,” said Samarakoon, ruefully.

After Upali Wijewardena disappeared his stables were up for offer. Seeing Samarakoon was a true animal lover, Chairman of the Upali Group, Dr. Seevali Ratwatte gifted all 12 horses to Samarakoon in 1983. The late Gamini Dissanayake extended Samarakoon the support necessary to make it an official breeding programme under the Mahaweli Authority banner.

Breeding a stock that were originally groomed for racing proved difficult as no records on their breeding capacity existed and there was a shortage of bloodlines. Samarakoon explained that it’s difficult to find studs of higher pedigree in the country. To make matters worse, the only stud was put down after it broke a leg. To date there are no studs in stables, only male foals. “It’s difficult to maintain studs because they tend to inbreed and impregnate mares that are too young,” explained Samarakoon, leading to a degenerate progeny. “You could lose control of the breeding programme.”

When a horse was killed in his stables, by insurgents who didn’t approve of his stern administration at the Authority, Samarakoon became disillusioned. He was forced to quit after 25 years in the Mahaweli Authority. Fortunately, in 1999, Rifle Corps Commanding Officer at the time, Colonel Ranjith Ellegala invited Samarakoon to continue his work at the Rifle Corps Headquarters premises, Pallekele. Samarakoon made sure to improve the bloodline of horses every new generation. Samarakoon believes that the progeny of the horses that he has bred can be improved to international standards.

Costs

Samarakoon explained that a horse of good breeding in Sri Lanka was priced somewhere between one million to 1.5 million rupees. For comparison, the world’s most expensive race horse, the Irish thoroughbred Galileo, is estimated at 180 million Euros, a staggering USD 215 million. The costs are just as exorbitant, according to Samarakoon. It costs Rs 500,000 to 600,000 per annum to raise a horse and he says there are no monetary benefits for him in horse breeding. His only reward is the foal he gets once a year. Samarakoon sells the male foals to those who are willing to provide a good home.

But he has donated a choice few to various establishments. He has offered 13 of the choicest studs to Sri Lanka Army and some to Sri Lanka Police. The last one, approximately Rs 400,000 in value, was gifted to the Gajaba Regiment Headquarters, Anuradhapura, three months ago. Three horses were offered to Sri Lanka Military Academy at Diyatalawa. Several more horses worth four million rupees were gifted to Sri Lanka Rifle Corps Headquarters, in reciprocation of allowing him to use the land for his breeding programme. Samarakoon still maintains these horses.

His free ranging horses at Pallekele are shampooed, groomed and examined for ticks regularly. He is of the opinion that horses raised for breeding purposes should not be ridden. “The animal’s mentality changes when it’s ridden,” said Samarakoon. “The bit alone weighs 750 to 800 grammes.

The high feed cost was another major concern at the inception of the programme. Most of the money allocated for the project was used up for horse feed. Armed with 40 years of experience in livestock breeding and farming, Samarakoon set about finding local alternatives. He substituted the feed with a locally concocted diet of energy and protein rich grains. The six locally sourced ingredients are mixed according to the ratio specified by Samarakoon, based on years of experience, depending on the nutritional requirements of individual horses. “For example, the diet of a weak animal is adjusted to provide more protein.” The horses are fed four to five kilos each twice a day in addition to being allowed to graze to their heart’s content in the 80 acre land belonging to the Rifle Corps Headquarters.

Samarakoon said calcium was vital to maintaining the bone strength, especially those of horses’ legs. Theirs is a curious diet of a calcium rich mixture, eggs, carrot and even banana. “Eggs are the most cost effective protein rich substance in Sri Lanka,” said Samarakoon. “And banana is a great laxative.” But, true to the idiom about the carrot and the stick, horses and donkeys, love carrot. Samarakoon said imported horses were fed on imported grain such as oats, bran and barley, supplemented by special imported vitamins.

“My horses are local and don’t need that. My objective is to breed truly local horses fed on a local diet.” About 70 percent of their diet consists of grass. Race horses require a specialised high protein diet. Samarakoon, who has reared Australian and Pakistani horses is of the view that even imported horses can be trained to consume local feed. “In fact, they come to like the variety of the local diet.” The diet introduced by Samarakoon costs only Rs 15,000 to 20,000, whereas maintaining them on imported feed would cost Rs 125,000 to 150,000 a month. The mash proved ideal for weight and height gain and blood tests proved that his diet plan was far better balanced than the imported variety.

 

Naturalised

The original objective of the breeding programme was to cross the Delft stock of ponies with horse or thoroughbred to produce a half-breed, a Sri Lankan horse, ideal in height, size and spirit. “You can turn a horse into a pony and a pony into a horse. In fact, the Delft ponies were once full-sized horses. But after their caretaker died, with nobody to care for them, they naturalised,” explained Samarakoon. He opined that instead of spending millions on importing stud sperm from abroad, horses could be cross-bred with Delft ponies to create a richer gene pool. “But not in the natural element of the ponies. They have evolved to the tough living conditions, drinking salt water and eating whatever little plant life is left during the dry season. A few could be taken out and introduced to the breeding programme.” Of course, if any government authority were to initiate such a programme, Samarakoon would be more than willing to give it a go.

With a lifespan 25 years, a horse is fit for riding for 20 years. “Speed is the benchmark of a pedigree and all the breeding in the world would do no good if they are not used in racing,” said Samarakoon. He pointed out that both Boossa and Colombo race courses had been closed down long back, and the only remaining horse racing venue, the Nuwara-Eliya racecourse, was in danger of closure. If there are no races, what will breeders like Samarakoon do? “This is a passion, not a business,” said Samarakoon. He is willing to take on a not so business-minded partner, who would take the reins, after he retires. He is ready to impart knowledge gathered over five decades on raising and breeding horses, to anyone interested in experimenting with horse breeding.

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.
