B.R. Ambedkar's magnum opus, The Buddha and his Dhamma, was barely completed before his death and was published posthumously in 1957. The book is known for Ambedkar's review and analysis of the vast Buddhist canon and literature. This is the first critical edition of The Buddha and his Dhamma. Along with a new Introduction, it includes footnotes indicating sources and annotations explaining various topics of discussion. The annotations provide useful information on canons like Suttas and Dhammapada indicating their authoritativeness in the Buddhist tradition and discuss the modifications effected in Ambedkar's use of the source material. An analytical index helps locate various passages and themes in the original text.
