The view and practice of quintessence dzoghen

This book presents three texts concerned with what is called in Tibetan the "Dzogchen" or, in English, "Great Completion" system of teaching that explains reality and how beings can return to it from their current, confused state. The texts explain the most profound level of that teaching being called "Nyingthig" or, in English, "Quintessence".

In Tibet, there were several lines of transmission of this Quintessence Great Completion level of teaching.  One came through a master named Longchen Rabjam, so it was called the Longchen Nyingthig meaning "Longchen Rabjam's transmission of the Quintessence Great Completion teaching".

This Longchen Nyingthig came down to a Tibetan man who grew up in the Dzachuka town of Eastern Tibet and became to be a great master of this particular teaching not to mention the Buddha's teachings as a whole. He was therefore known as "Dza Pal Trul" meaning "the glorious (pal) manifestation of enlightenment (trul) from the town of Dza".
