Dzogchen: The word Dzogchen has been translated variously as Great Perfection, Great Completeness, Total Completeness, Supercompleteness. These terms also convey the idea that our nature as intrinsic awareness has many qualities that make it 'perfect'. These include indestructibility, incorruptible purity, non-discriminating openness, flawless clarity, profound simplicity, all-pervading presence and equality within all beings (i.e., the quality, quantity and functionality of this awareness is exactly the same in every being in the universe). It is said that the impressive personal qualities of the fully-enlightened Buddha derived from the fact that he was fully 'aligned' with this already-existing primordial nature. Descriptions of the Buddha as omniscient, omnipotent and omnipresent refer to his ultimate nature as this awareness. The term Dzogchen is a Tibetan rendering of the Sanskrit term maha sandhi and its variants, and is also used to render the Sanskrit term ati yoga.

The homonymous term Dzogchen designates a meditation practice and body of teachings aimed at helping an individual to recognize the Dzogchen state, to become sure about it, and to develop the capacity to maintain the state continually.
