"Ambedkar tested every big and small, old and new religion available to Indians, trawled the texts and tenets of Hindus, Buddhists, Muslims, Sikhs, and Christians, and indeed made himself an entire career as a scholar of comparative religions alongside his enormously busy public life as a mass leader, a politician, and an intellectual. He was far more systematic than Gandhi as a self-taught student of different religions in India, far more thorough than Nehru as an amateur historian of India, far more imaginative and conflicted than the talented Tagores in his attempt to identify or construct an acceptable past for the emerging nation. Even as he stood every received theory about the origins and evolution of the caste system on its head, he declared his fervent intention to "annihilate" caste. It is no wonder that Ambedkar remains the least understood of the great moderns that India produced, and who produced India." More here.
