Pith Instruction Class
Pith Instruction Class (mengak dé) - One of the three classes into which Manjushrimitra divided the Dzogchen teachings. Shri Singha arranged the teachings of the Pith Instruction class into four cycles:
- the outer cycle, which is like the body, intended for those of lesser capacity
- the inner cycle, which is like the eyes, intended for those of medium capacity
- the secret cycle, which is like the heart, for those of the highest capacity
- the innermost secret cycle, which is like the whole person, intended for those of exceptionally high capacity
