"“I want to see you, Swami,” I began, “on this matter of receiving back into Hinduism those who have been perverted from it. Is it your opinion that they should be received?” Certainly, they can and ought to be taken... And then every man going out of the Hindu pale is not only a man less, but an enemy the more. .... Again, the vast majority of Hindu perverts to Islam and Christianity are perverts by the sword, or the descendants of these. It would be obviously unfair to subject these to disabilities of any kind."
