The Treasury Of Knowledge: Book Six, Part Four: Systems Buddhist Tantra: 6

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.
