It's impressive that a man [Dalai Lama], on the day after his Nobel Prize was announced, in October, 1989, said to me, "I really wonder if my efforts are enough?" Most of us, if we just won the Nobel Prize, would think this is vindication, or at last there's a chance for Tibet. He's the rare person who thinks, as a Buddha would, "I don't know if I've done enough, I don't know if I will do enough."
