What is "menngagde"

In Tibetan Buddhism and Bon, Menngakde (, THL: men-ngak-dé, ), is the name of one of three scriptural and lineage divisions within Dzogchen (Great Perfection ).

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.
