Essence, nature, and capacity
Essence, nature, and capacity (ngo bo rang bzhin thugs rje). The three aspects of the sugata-garbha according to the Dzogchen system. Essence is the primordially pure wisdom of emptiness. The nature is the spontaneously present wisdom of cognizance. The capacity is the all-pervasive wisdom of indivisibility. This is, ultimately, the identity of the Three Roots, the Three Jewels and the three kayas.
