Conversion, for most of these individual sects, was an alien idea. Opting out of the sect one identified with could also affect one’s caste identity, and a person without a caste identity was regarded as an outcaste, and of little consequence in the larger society. A caste identity would continue if a caste as a collective converted, as often happened in conversions to Islam or Christianity. All religions in India, irrespective of their theoretical support of social equality, maintained caste distinctions—especially in the codes of marriage and inheritance.
