Five Wisdoms, Five Buddha Families and Five Poisons, by Dzogchen Ponlop Rinpoche
Excerpt from ‘Penetrating Wisdom: The Aspiration of Samantabhadra’ published in 2006.

FIVE WISDOMS. The next section of the Prayer [The Aspiration of Samantabhadra] talks about the self-appearing spontaneous wisdom within which, in the case of Samantabhadra, full awakening is manifested. The absolute reality of rigpa, which is the true essence of wisdom, the true fundamental nature of phenomena, arises from this one nature. The spontaneous wisdom of kadak manifests within this one absolute reality.
