Dear Rowan,
Here is translation of Osho's original speech on "cross breeding" delivered in Hindi language.
".......Cross breeding is the superior breeding. There is possibility of generating 'superior' from cross breeding. You are using this in the seeds......Using in the animals. Not using in human yet. That's why today'breeding of human is backward than that of animal.
Today we produce better dog amongst dog, but can't produce better human amongst human. Reproduction system in human is still unscientific. Still we are not caring about producing better human, with more healthy body and mind. We care about seed. Seeds of fruits, flower, wheats etc are becoming better. We are caring to produce better animal among animals. but not in human. In old age it was assumed that interrace or intercaste sex will produce hybrid & inferior child. But in real allintellectual & developed community & culture in the world is hybrid. All 'pure' community are backward. Nigro are pure, African tribals are pure, Indian tribals are pure.
All developed civilization, culture are hybrid. Like two different stream meat and make a mighty river in the same way two stream of life produce more prosperous life. if the old wisdom was true then brother & sister should have married & produce 'pure' child. But, not child will be unhealthy. We stop brother and sister( to marry). Wise people stop even cousins. Wiser will will not marry in their community. Person more wiser will not marry in their country. And if we are able to find 'human' on any other planet wisest people will think about 'inter-planetory cross-breeding"............
