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:

1. the outer cycle, which is like the body, intended for those of lesser capacity
2. the inner cycle, which is like the eyes, intended for those of medium capacity
3. the secret cycle, which is like the heart, for those of the highest capacity
4. the innermost secret cycle, which is like the whole person, intended for those of exceptionally high capacity
