Dzogchen or the Natural Great Perfection is our true nature. It’s the realization of pure awareness prior to mentation yet from it comes mentation. It is the non dual state.
Your very nature is awareness with the qualities of joy, equanimity and a wisdom that surfaces at the appropriate time. There is a bodily relaxation component as the mind chatter is significantly reduced from the realization of felt oneness, a oneness full yet empty.
Also there is the realization that the personal relative inside space of pure consciousness is the very same as the apparent outside space, again all is as it is relatively full, absolutely empty.
‘Happiness is the way’. Keep going back to that uncaused inner bliss fire, and its naked awareness.
