Tulku Urgyen's Great-Grandfather

Tulku Urgyen's Great-Grandfather Chokgyur Lingpa was a major revealer of hidden treasures. His collected works comprise more than 40 volumes and is known as Chokling Tersar, the New Treasures of Chokgyur Lingpa. He was both teacher and disciple of Jamyang Khyentse and Jamgon Kongtrul, and these three masters are famed for having initiated the nonsectarian Rimey movement in the late 19th century.
