The following is an excerpt from Carl Sagan’s meeting with the Dalai Lama

“…in theological discussions with religious leaders, I often ask what their response would be if a central tenet of their faith were disproved by science. When I put this question to the Dalai Lama, he unhesitatingly replied as no conservative or fundamentalist religious leaders do: In such a case, he said, Tibetan Buddhism would have to change. Even, I asked, if it’s a really central tenet, like reincarnation? Even then, he answered. However, he added with a twinkle – it’s going to be hard to disprove reincarnation.”
