The second volume of the Trilogy by the thirteenth-century Nyingma master Longchenpa opens with a helpful description of environments that complement different types of practice; a second section describes the qualities useful for those aspiring to the path; and a third section gives detailed instructions for preliminary and advanced practices with descriptions of the resulting experiences. The aim of these meditations is to encounter directly the radiance of awareness.Translated by H.V. Guenther with extensive notes."There can be few texts of such overwhelming importance as guides to the marvelous mind-training techniques perfected in Tibet." – John Blofeld
