In this book Namkhai Norbu gives instructions for developing clarity within the sleep and dream states. He goes beyond the practices of lucid dreaming that have been popularized in the West, by presenting methods for guiding dream states that are part of a broader systemfor enhancing self-awareness called Dzogchen. In this tradition, the development of lucidity in the dream state is understood in the context of generating greater awareness for the ultimate porpose of attaining liberation. This revised and enlarged edition includes additional material from a profound and personal Dzogchen book which Namkhai Norbu has been writing for many years. This material expands and deepens the first edition's emphasis on specific exercises to develop awareness within the dream and sleep states. Also included in this book is a text written by Mipham, the nineteenth-centruy master of Dzogchen, which offers additional insights into this extraordinary form of meditation and awareness.
