Three Classes of the Great Perfection
The Three Classes of the Great Perfection (Tib. རྫོགས་ཆེན་སྡེ་གསུམ, Dzogchen Desum; Wyl. rdzogs chen sde gsum) is a revelation of Chokgyur Dechen Lingpa and Jamyang Khyentse Wangpo. It was revealed in 1857 at Meshö Dzomnang as an earth terma taken from the Lotus Crystal Cave, a cave sacred to Guru Rinpoche. Tulku Urgyen Rinpoche described it as Chokgyur Lingpa's foremost treasure, as it is the only Tibetan terma to reveal all three classes of Dzogchen.
