Dozgchen means great perfection or great completion, etc. It is a direct method, (or non-method) with self-knowing awareness itself, (rigpa) as the vehicle.
Dzogchen (Wylie: rdzogs chen, "Great Perfection" or "Great Completion" ), also known as atiyoga (utmost yoga), is a tradition of teachings in Indo-Tibetan Buddhism aimed at discovering and continuing in the ultimate ground of existence.[1] One's primordial ground (ghzi, "basis" ) is said to have the qualities of purity (i.e. emptiness), spontaneity (lhun grub, associated with luminous clarity) and compassion (thugs rje). The goal of Dzogchen is knowledge of this basis, this knowledge is called rigpa (Skt. vidyā ). There are numerous spiritual practices taught in the various Dzogchen systems for awakening rigpa. Dzogchen developed in the Tibetan Empire period and the Era of Fragmentation (9-11th centuries) and continues to be practiced today both in Tibet and around the world. It is a central teaching of the Yundrung Bon tradition as well as in the Nyingma school of Tibetan Buddhism.[quote 1] In these traditions, Dzogchen is the highest and most definitive path of the nine vehicles to liberation.[2] Dzogchen is also practiced (to a lesser extent) in other Tibetan Buddhist schools, such as the Kagyu and the Gelug school.
