After the Mohammedan conquest of Persia, about a hundred thousand of these people came to India and took shelter there, and some remained in Persia. Those who were in Persia, under the constant persecution of the Mohammedans, dwindled till there are at most only ten thousand. In India there are about eighty thousand of them, but they do not increase. And then, this handful of persons living in India, with the pernicious custom of cousin-marriage, does not multiply. With this single exception, all the great religions are living, spreading, and increasing.
Every religion is of Asiatic origin and belongs to that part of the world.
If what the modern scientists say is true, that the survival of the fittest is the test, these religions prove by their still being alive that they are yet fit for some people. Look at the Mohammedans, how they are spreading in some places in southern Asia, and spreading like wildfire in Africa. The Buddhists are spreading over central Asia all the time. Christianity, you all know, is spreading-though I am not sure that the results are equal to the energy put forth. Preaching has always been the business of the Asiatics.
