Kyabjé Drikung Kyabgon Chetsang Rinpoche is the 37th throne holder of the Drikung Kagyu lineage of Tibetan Buddhism, and held to be the 7th reincarnation of the Chetsang Rinpoche, a manifestation of Chenrezig (Sanskrit: Avalokiteshvara), the Buddha of Compassion (as are the Dalai Lamas). He is based at the Drikung Kagyu Institute at Dehra Dun, India, where he established the Songtsen Library, a center for Tibetan and Himalayan studies.

His Holiness Chetsang Rinpoche was born in Lhasa, Tibet into the well-known Tsarong family. In 1949, he was recognized as the 37th Drikung Kyabgon, head of the Drikung Kagyu order of Tibetan Buddhism, and shortly thereafter received his religious vows from H.H. the 14th Dalai Lama. At Drikung Thil, the principal seat of the order, Rinpoche received from the many distinguished teachers there all of the important Kagyu teachings, initiations, and transmissions. His religious training was interrupted by the political situation in Tibet, when he was forced to attend a Chinese school in Lhasa and then was sent to work on a farm. Finally, in 1975, he was reunited with his family and followers in India, where he completed his formal spiritual training and a three-year meditation retreat and then set about rekindling the embers of his lineage. He has worked tirelessly to renew and spread its academic and meditative traditions in many countries including the USA.
