"I have seen people who are born in the lowest category of Hindu law, the sudras, the untouchables, so intelligent: when India became independent, the man who made the constitution of India, Dr. Babasaheb Ambedkar, was a sudra. There was no equal to his intelligence as far as law is concerned — he was a world-famous authority... Ambedkar was educated in England, and he became the world-famous authority as far as constitutions are concerned. And when he came back to India, India became free and there was no choice; nobody was even close to him..."
