DZOGCHEN SAMAYA, primarily, introduces Dzogchen as an indissoluble bond to the nature of mind. At the heart of Dzogchen there is no vow to maintain and no commitment to keep, but the Dzogchen SAMAYA is the crucial pact of inborn union. That unity in the nondual nature of mind, the ineffable nature of the Dzogchen SAMAYA, is the principal subject of this book contained in its short but vital first pages . The second part of the book deals with the tantric samayas, the practical commitments that fine tune the conduct of the Dzogchen yogin or yogini in his spontaneous response to the needs of sentient beings and the planet. Sexuality looms large in that body of response. This is number 4 in the series of Dzogchen teaching manuals. Keith Dowman is a translator and teacher in the Tibetan tradition.
