This book belongs to the same cycle of teachings as The Tibetan Book of the Dead. Giving instruction on the method of "self-liberation", it presents the essence of Dzogchen, regarded in Tibet as one of the most advanced teachings of the Buddha. John Myrdhin Reynolds (Vajranatha) was trained and ordained as a Tantric Yogin in the Nyingmapa tradition of Tibetan Buddhism and has taught widely in the U.S. and Europe.

"This text is perhaps the clearest, most comprehensive and accessible of medium-length writing on rigpa and as such is highly recommended."
