Three categories

Mañjushrimitra

Three categories or three classes (Tib. dé sum; Wyl. sde gsum) — the three categories into which Mañjushrimitra divided the Dzogchen teachings he received from Garab Dorje:

1. the outer category of mind (semdé),
2. the inner category of space (longdé), and
3. the category of pith instructions (mengak dé).
