Modern scholar and Nyingma master Khangsar Tenpa'i Wangchuk composed this first and only commentary on the fourteenth-century Buddhist master Longchenpa's essential text, The Precious Treasury of the Fundamental Nature. The root text establishes the definitive view of the secret class of pith instructions of Dzogchen, the Great Perfection. Tenpa'i Wangchuk's word-commentary elucidates the nature of phenomena adhering closely to the internal structure of Longchenpa's verses, clearly presenting the four vajra principles of the nature of phenomena: nonexistence, evenness, spontaneous presence, and single nature.

The Padmakara Translation Group has provided a clear and fluid new translation of Longchenpa's root text. The commentary by Khangsar Tenpa'i Wangchuk is here translated for the first time, commencing an extended project to render his entire collected works in English. This is an invaluable resource for students of Buddhism who wish to deepen their understanding of the nature of mind and phenomena as presented in the Great Perfection tradition.

Longchen Rabjam (1308-1363), also known as Longchenpa, is a great luminary of Tibetan Buddhism. He was highly skilled in all aspects of scholarship from an early age and excelled throughout his life in the practice and accomplishment of the Dharma. Regarded as a great Dzogchen master, Longchenpa had many pure visions where he was given direct instructions from Guru Padmasambhava and is recognized as an emanation of Vimalamitra. Longchenpa's prolific writings have made him one of Tibet's most renowned and precious teachers.

Khangsar Tenpa'i Wangchuk (1938-2014) was born in Golok, Tibet. Khangsar Khenpo began his Buddhist study at eight years old, became a monk at fourteen, and began teaching at fifteen. A Nyingma practitioner, Khangsar Khenpo was both a terton, or treasure revealer, and a scholar of the rigorous scholastic curriculum of the Geluk tradition. During the later years of the Cultural Revolution, he was sentenced to twelve years in prison, where he continued his dedicated practice alongside other great masters, from whom he received pith instructions and transmissions. In the later part of his life, he focused on teaching, writing commentaries on seminal texts, and restoring and enlarging monasteries in his home villages of Khangsar Taklung and Payak in the region of Golok.

The Padmakara Translation Group, based in France, has a distinguished reputation for its translations of Tibetan texts and teachings. Its work has been published in several languages and is renowned for its clear and accurate literary style.
