In Tibetan religious literature, Jamgön Kongtrül's Treasury of Knowledge in ten books stands out as a unique, encyclopedic masterpiece embodying the entire range of Buddhist teachings as it was preserved in Tibet. The tantric path is often referred to as the indestructible way of secret mantra, the essence of which is the indestructible union of wisdom (the understanding of emptiness) and method (immutable great bliss). This volume sets forth the various systems that constitute this path, both those of the ancient tantra tradition and of the new tradition.
The first Jamgon Kongtrul, Jamgön Kongtrül Lodrö Thayé (འཇམ་མགོན་ཀོང་སྤྲུལ་བློ་གྲོས་མཐའ་ཡས་ 'jam mgon kong sprul blo gros mtha' yas), was one of the preeminent scholars in 19th century Tibet, often referred to as Jamgon Kongtrul the Great. The name Kongtrul is a contraction of Kongpo Bamtang Tulku, of whom he was held to be an incarnation. He also was a tertön, or "revealer of Dharma treasures," and in that capacity was given the name Pema Garwang Chimé Yudrung Lingpa.
He was also a respected physician and diplomat. He is credited as one of the founders of the Rimé (རིས་མེད་ ris-med "unbiased" or non-sectarian) movement of Tibetan Buddhism, and he compiled what is known as the Five Great Treasuries.
