In 1991, I went with a group of students with Thrangu Rinpoche to do the Namo Buddha Pilgrimage in India. We went to Rajgir at the famous Vulture Peak Mountain and recited The Heart Sutra! When we got at the top of the mountain, I was very tired and I said to Thrangu Rinpoche: "Is it really true that it is good to do this?" He said: Yes, it is very good. Then I said: You promise me! And then he said: No, YOU promise me!
