Death, intermediate state and rebirth in Tibetan Buddhism

by Jeffrey Hopkins.
Ithaca : Snow Lion Publications, 1985.

This  book unfolds in detail the complex Tibetan Buddhist system of subtle physiology, providing a complete exposition of the channels, drops, and winds which serve as foundations for consciousness. Highest Yoga Tantra simulates processes of death, intermediate states, and rebirth, so it is important for the practitioner to know how humans die—the stages of death, and the physiological reasons behind them.
