Longchenpa, or Longchen Rabjam—(1308–1363) was a Tibetan Buddhist teacher, one of the most significant authors in the history of the Nyingma school, and a systematizer of Dzogchen teachings. He left behind an enormous literary legacy—a series of philosophical poetic texts distinguished by balanced structure and aphoristic quality.
Excerpts from his books: The Precious Treasury of Dharmadhatu, The Great Garuda — Wings of Perfection, A Ship of Precious Gems.
