Swami Vivekananda, The Complete Works of Swami Vivekananda, Mayavati, Advaita Ashrama, 1954, vol. 3, p. 533-534; ce passage est tiré d'une conférence intitulée « Buddhistic India », prononcée au Shakespeare Club, Pasadena, Californie, le 2 février 1900, texte consultable sur la Wikisource anglaise. Cité par G. B. Singh, Gandhi. Behind the Mask of Divinity, Prometheus Books, 2004, p. 239-240 : « There is something in caste, so far as it means blood; such a thing as heredity there is, certainly. Now try to [understand] — why do you not mix your blood with the Negroes, the American Indians? Nature will not allow you. Nature does not allow you to mix your blood with them. There is the unconscious working that saves the race. That was the Aryan's caste. Mind you, I do not say that they are not equal to us. They must have the same privileges and advantages, and everything; but we know that if certain races mix up, they become degraded. With all the strict caste of the Aryan and non-Aryan, that wall was thrown down to a certain extent, and hordes of these outlandish races came in with all their queer superstitions and manners and customs. Think of this: not decency enough to wear clothes, eating carrion, etc. But behind him came his fetish, his human sacrifice, his superstition, his diabolism. He kept it behind, [he remained] decent for a few years. After that he brought all [these] things out in front. And that was degrading to the whole race. And then the blood mixed; [intermarriages] took place with all sorts of unmixable races. The race fell down. But, in the long run it proved good. If you mix up with Negroes and American Indians, surely this civilisation will fall down. But hundreds and hundreds years after, out of this mixture will come a gigantic race once more, stronger than ever; but, for the time being, you have to suffer. The Hindus believe — that is a peculiar belief, I think; and I do not know, I have nothing to say to the contrary, I have not found anything to the contrary — they believe there was only one civilised race: the Aryan. Until he gives his blood, no other race can be civilised. No teaching will do. The Aryan gives his blood to a race, and then it becomes civilised. Teaching alone will not do. He would be an example in your country: would you give your blood to the Negro race? Then he would get higher culture. »
