The Dalai Lama (Lhamo Dhondrub)
[Spiritual leader, b. 1935, Taktser, Tibet, lives in exile.]
I know the earth is round by relying on the words of someone who has seen it and proved it with photographs... You have to rely on a person who has already had this kind of experience and has no reason to tell lies.
(Explaining the Buddhist concept of extremely hidden phenomena.)
