What did Ambedkar say about worshipping leaders?
He warned against it in the strongest terms he used anywhere in the speech. There is nothing wrong, he said, with being grateful to great men who have served the country; but there are limits to gratefulness. Bhakti, or hero-worship, which plays a part in the religion of India unequalled by any other country's politics, is in politics a sure road to degradation and to eventual dictatorship. Devotion laid at the feet of a person, rather than kept for the cause, is how free peoples talk themselves into a strongman.
He borrowed the point from an English liberal thinker: to place your liberties at the feet of even a great man, or to trust him with powers that let him subvert the institutions, is unwise. The safeguard is not to find a better hero but to stop needing one — to keep the loyalty attached to the rules and the institutions, which outlast any individual, rather than to a face.
Coming from a man who was himself worshipped by millions, and still is, this is a pointed thing to have said. He was, in effect, telling his own followers not to do to him what he was warning them not to do to anyone. It is the most useful warning in the speech for a generation deciding whom to trust with power.
