Dzogchen Verse (8)

The very meaning of Buddha Nature - Dharmakaya without transition or change, awareness supremely free of limitation, the Ground of Being as basic space - the true nature of phenomena that is immediately present, a supreme and inexpressible state that is nothing in and of itself, an unrestricted state of resting in the fundamental nature beyond ordinary consciousness - That is the key point of practice and to attainment of supreme timeless awareness. There are no obscurations if your very essence recognizes itself. Buddhahood is none other than your own natural Ground of Being.

( Dudjom Lingpa, Nang Jang- Refining One's Perception )
