5 June 1950: Dr. Amebdkar addressed an international gathering at Colombo, Sri Lanka
In the speech he explained the rise and fall of Buddhism in India and the opportunistic conspiracy of Brahmins. Excerpts of his speech:
“I disagree with the view that Hinduism has all along been the religion of India. Hinduism is the latest development of social thought in India.”
“It was during brahmanic period that Buddhism was born. This was because Buddhism opposed inequality, authority and division of society in various classes which Brahmanism had introduced in India.”
“The vedic Aryans used to worship innumerable gods. They used to please them by performing yagyas. The puja to be performed for these gods should necessarily be sacred and superb. In those agrarian times, cows were the chief wealth of the Aryans. Therefore, they used to sacrifice cows to honour their deities. In this way, Vedic dharma encouraged violence…………… They said that the Brahmins were born of Brahma’s mouth and Shudras from his feet. Can anybody believe that basic principle of any religion could be to divide the society? Yet this is what Brahmanism has perpetuated. On the other hand, equality is the main feature of Buddhism. The religion of the Buddha gives freedom of thought and freedom of self-development to all. To abjure violence is another essential teaching of Buddhism……… I would say that the rise of Buddhism in India was as significant as the French Revolution. ……….. Buddhism paved the way for establishment of democracy and socialistic pattern of society in India.”
“Buddhism appears to have met strong opposition in 184 B.C. when the last Maurayan King was assassinated by his chief commander. This was one of the awful actions of the Brahmins to save their religion. But it is a pity that the historians have not given sufficient importance to his incident. While going through the Buddhist literature, I find that 90 percent followers of the Buddha were brahmins. …….., how is that Buddhism that had flourished among the majority of Brahmins was later on destroyed by the Brahmins themselves.”
“In my opinion the main reason for this was the family deity’s (kula deva) worship. …….. Asoka after embracing Buddhism discontinued this practice and removed the idols of such deities. ………….. This action of Asoka disturbed the bahmins very much ……………..”’
“The brahmins were of the view that after death, kings go to hell because of their errors and omissions. Therefore, they did not agree to be rulers but preferred to be the chief advisers to the kings. In order to take revenge for the loss they suffered on account of stoppage of kulapuja, brahims gave up the approved motto of being advisers only and tried to grab power. With the help of their well-wishers kshatriyas, they also organized an united Brahmin-kshatriya axis against Buddhism. The ascendancy of Brahmanism again in India society is one of the reasons for the downfall of Buddhism.”
“The foreign invasions are also responsible for the decline of Buddhism in India. ……………………..Hunds tried to destroy Buddhism. The religion of the Buddha got the severest blow from the Muslim invasion. They destroyed the Buddhist idols and killed the Bhikkus. They mistook the great Nalanda University as the Fort of Buddhists and killed a large number of monks thinking that they were soldiers. The few Bhikkus who escaped the onslaught fled away to the neighboring countries like Nepal, Tibet and China.
“Some of my Hindu friends often ask why Hinduism, which has also idol-worship, survived in India and Buddhism died. My answer is that whatsoever the religion may be, it requires the priest community to preserve it. Due to the shortage of Buddhist monks, Buddhism declined. Efforts were subsequently made by some Buddhists to raise another priesthood in order to revive Buddhism but their efforts failed. Such is not the case with Hinduism. A brahmin’s son is priest by birth. Therefore, no separate priest community is required to protect their religion. This is why Hinduism survived Muslim onslaught. Moreover, Buddhism as a religion is difficult to practice which Hinduism is not. ………”
“I do not agree with the suggestion made by many people in India that Buddhism was destroyed by the dialectics of Shankaracharya. This is contrary to the facts as Buddhism existed for many centuries after his death. In my opinion, Shankarachayra himself was a Buddhist. His guru too was a Buddhist. Of course, Buddhism declined in India because of the rise of Vaishnavism and Saivism, the two cults which adopted and absorbed many points of Buddhism. Today. Hinduism is in a very much changed form. Hinduism which taught and practiced violence earlier has started teaching non-violence. This has been copied from Buddhism. Buddhism may have disappeared in material form but as a spiritual force it still exists in India.”
