Dzogchen is referred to as the natural, primordial state of our being. This all-encompassing primordial clarity is the nature of all beings. Dzogchen is the “Great Perfection” and core essence of the Nyingma school of Tibetan Buddhism and of Bon. The Dzogchen is the pinnacle of all vehicles of Buddhist teachings.  

Sogyal Rinpoche describes it as

"the heart-essence of all spiritual paths and the summit of an individual’s spiritual evolution".
