Sangharakshita 
Dr Ambedkar and the Revival of Buddhism I [EPUB ebook] 

One of the most far-reaching of Sangharakshita’s contributions to modern Buddhism was giving shape to the Buddhist conversion movement begun by the great Indian statesman and reformer, Dr B.R. Ambedkar. The first part tells the story of how Ambedkar overcame the suffering and struggle of his early years to become the shaper of the Indian constitution and the leader of his people to a new life. The second part is a collection of 36 talks from Sangharakshita’s tour of the Buddhist communities in India in 1981-2.
