The all-knowing Longchenpa (1308-64) stands at the center of the Nyingma tradition. Acknowledge by all schools of Tibetan Buddhism as one of Tibet's greatest masters.
Among the works in Longchen Rabjam's famous collection - the Seven Treasuries - is this book commonly known as the Chöying Dzod.
The Chöying Dzod consists of two texts:
• a set of source verses entitled The Precious Treasury of the Basic Space of Phenomena
• and Longchenpa's own commentary on those verses - A Treasure Trove of Scriptural Transmission (in which the source verses are included).
Although published individually, they are considered companion volumes.
