Menngagde (Wylie: man ngag sde; THDL phonetics: men-ngak-dé), (Sanskrit: upadeshavarga), translated as "Secret oral instruction division", "Secret oral instruction series," "Secret oral school", or "Quintessential Instructions Series", or "The Category of Direct Transmission", is the name of one of three scriptural and lineage divisions within Atiyoga (Tib. Dzogchen, Great Perfection) teachings. Dzogchen is itself the pinnacle of the ninefold division of practice according to the Nyingma school of Tibetan Buddhism. Menngagde focuses on the practices in which one engages after gaining confidence in knowledge of the state of rigpa, emphasizing the inseparability of space and mind from the very beginning (dbyer-med). It is this inseparability that fundamentally characterizes the Dzogchen view
