From Questions and Answers of Volume 5 of The Complete Works of Swami Vivekananda
Q.—Did Vedanta exert any influence over Mohammedanism?
A.—This Vedantic spirit of religious liberality has very much affected Mohammedanism. Mohammedanism in India is quite a different thing from that in any other country. It is only when Mohammedans come from other countries and preach to their co-religionists in India about living with men who are not of their faith that a Mohammedan mob is aroused and fights.
Q.—Does Vedanta recognise caste?
A.—The caste system is opposed to the religion of the Vedanta. Caste is a social custom, and all our great preachers have tried to break it down. From Buddhism downwards, every sect has preached against caste, and every time it has only riveted the chains. Caste is simply the outgrowth of the political institutions of India; it is a hereditary trade guild. Trade competition with Europe has broken caste more than any teaching.
Q.—What is the peculiarity of the Vedas?
A.—One peculiarity of the Vedas is that they are the only scriptures that again and again declare that you must go beyond them. The Vedas say that they were written just for the child mind; and when you have grown, you must go beyond them.
Q.—Do you hold the individual soul to be eternally real?
A.—The individual soul consists of a man’s thoughts, and they are changing every moment. Therefore, it cannot be eternally real. It is real only in the phenomenal. The individual consists of memory and thought, how can that be real?
Q.—Why did Buddhism as a religion decline in India?
A.—Buddhism did not really decline in India; it was only a gigantic social movement. Before Buddha great numbers of animals were killed for sacrifice and other reasons, and people drank wine and ate meat in large quantities. Since Buddha’s teaching drunkenness has almost disappeared, and the killing of animals has almost gone.
