The Dalai Lama on Dzogchen and Rigpa:..

“Dodurupchen says that all phenomena are quite definitely such that they arise as rigpa’s energy or rigpa’s display. From the point of view of the new schools of tantra (sarma), everything that appears arises as the display of great bliss, and the display of emptiness. In the terminology of Dzogchen whatever manifests arises as the display of rigpa, and that is certain. So the agent responsible for all of this as well as the space and ground for it all, is the single state of Clear Light. Everything, in fact , is the display or array of Clear Light… Such experiences of Clear Light will arise, and when they do, you are left without any fear of falling into samsara: you are left without any hope of attaining nirvana: you are left without any hope or fear whatsoever. All experiences and all feelings, be they good or bad, karma, its results, birth and death and change: all of this manifests as the magical display of Clear Light.
