In Tibetan Buddhism and Bon, Menngagde (Tibetan: མན་ངག་སྡེ, Wylie: man ngag sde, THL: men-ngak-dé, Sanskrit: upadeśavarga), is the name of one of three scriptural and lineage divisions within Dzogchen (Great Perfection atiyōga). Dzogchen is itself the pinnacle of the ninefold division of practice according to the Nyingma school of Tibetan Buddhism. Menngagde focuses on rigpa. The Menngagde or 'Instruction Class' of Dzogchen teachings are divided into two parts: trekchö and tögel.
