In 1991 Carl Sagan an The Dali Lama sat down to talk about Science and Religion. Carl Sagan asked the Dali Lama about his beliefs and as a buddhist what he would do if a scientific discovery conflicted with Buddhist doctrine. The Dali Lama said that even Buddha questioned his teachings and that Buddhists consider doctrine to be discoveries rather than scripture.
Carl Sagan: “So there is no conceivable scientific finding that would make you no longer consider yourself a Buddhist?”
Dali Lama: "Buddhism is not so much a religion, but a ‘science of the mind’ or an ‘inner science’ … there is much benefit to learning from scientists’ findings."
"If through thorough investigation things become clear, only then is it time to accept and believe.”
