Longchenpa; translated by the Padmakara Translation Group

"This volume of Longchenpa's Seven Treasuries focuses on the four great samayas of Dzogchen: ineffability, openness, spontaneous presence, and oneness. In support of his presentation, Longchepa quotes extensively from the Dzogchen tantras, as well as from Garab Dorje, Nagarjuna, Shri Singha, Padmasambhava, and other great masters of the Buddhist tradition"--
