Dr. B.R. Ambedkar educated himself as a the most qualified person of his time, inspired untouchable castes to reject Brahmanical Social Order (BSO) that kept them socially degraded, economically poor, culturally despised, politically powerless, and denied them the basic human rights. Dr. B.R. Ambedkar prescribed 22 vows to his followers during the historic religious conversion to Buddhism on 15 October 1956 at Deeksha Bhoomi, Nagpur in India. The conversion to Buddhism by 800,000 people was historic because it was the largest religious conversion, the world has ever witnessed. He prescribed these oaths so that there may be complete severance of bond with Hinduism. These 22 vows struck a blow at the roots of Hindu beliefs and practices. The book, which provides a rare opportunity to debate and discuss the contribution of Dr. Ambedkar in nation-building, will be great interest to all sections of people.
