Garab Dorje (Fl. 55 CE) (Tibetan: དགའ་རབ་རྡོ་རྗེ་, Wylie: dga’ rab rdo rje) was the semi-historical first human teacher of the Ati Yoga (Tib. Dzogchen) or Great Perfection teachings according to Tibetan Buddhist tradition. Prior to Prahevajra, the Nyingma hold that the Dzogchen teachings had been expounded only in celestial realms and the pure lands (Sanskrit: śuddhanivāsa) of the Buddhas, Devas and Nāgas. The Bonpo have a different view of the entry of Dzogchen into the lineages of humanity.
