Rahob Rinpoche Thupten Kalsang was recognized at the age of one through a dream of the Fifth Dzogchen Rinpoche Thupten Chukyi Dorje as the reincarnated Head Lama Jyamyang Drupbai Wampo. After much observation and the approval from his parents, Rahob Rinpoche followed traditional studies and trainings at his monastery.
In 1952 he began his seven years education at Drepunt University in Lhasa. Later after graduating from Varanasi Sanskrit University in India, he spent ten years practicing in the Theravadan tradition in Thailand and seven years teaching and working with Zen and Shingon Masters in Japan. In 1979 he received an invitation as an adjunct professor and taught two years each at University of Massachusetts, Harvard Divinity School and Tuft University Theology Department before becoming an American.
