Among the works in Longchen Rabjam's famous collection - The Seven Treasuries - commonly known as the Chöying Dzöd - concerns the spiritual approach known as trekcho (cutting through solidity), which brings spiritual practitioners of the highest acumen to freedom effortlessly. The Chöying Dzöd consists of two texts:
- The Precious Treasury of the Basic Space of Phenomena - source verses
- A Treasure Trove of Scriptural Transmission - Longchenpa's own commentary on those verses
Each of these has been published separately.
This book - A Treasure Trove of Scriptural Transmission - contains commentary with source verses interspersed.
