His Holiness the Dalai Lama just told Larry King that gay marriage is "OK" -- "I think it's individual business. If two people--a couple--really feel that way is more practical, more sort of satisfaction, both sides fully agree, then OK " In light of previous statements by His Holiness that homosexual sex amounts to "sexual misconduct," this seemed to be a reversal of his prior view.
But it isn't really, if you look at the issue from his perspective. I wrote an article explaining the Dalai Lama's views on homosexuality and gay marriage, based on things he has said going back a few years. It's important to understand also that the Dalai Lama doesn't speak for all of Buddhism on matters regarding sexuality, just Tibetan Buddhism.
