Rigdzin Jigme Lingpa (1730–1798) was a great master of the Nyingma tradition of Tibetan Buddhism. The root of the Khyentse lineage, he was a tertön, or discoverer of treasure teachings, and revealed the Longchen Nyingtik, one of the most important cycles of meditative practice in the Nyingma school.

Lama Chönam Chöying Namgyal was born in the Golog area of eastern Tibet in 1964. His root teacher, Khenpo Munsel, was a direct disciple of Khenpo Ngagchung and was himself one of the great authentic Dzogchen masters of the twentieth century. Lama Chönam escaped Tibet in 1992 and later came to the United States, where he resides today. Over the past sixteen years, Lama Chönam has been teaching Tibetan language and the Buddhadharma. He is one of the founders of the Light of Berotsana Translation Group.
