The Marvelous Primordial State of Great Perfection is a profoundly important root text of the Mind series of Dzogchen. Although this ancient text is not as large, nor has it as many chapters as The Supreme Source, it teaches all the essential principles of Ati Dzogchen that can be subsumed in the view without fixations, contemplation beyond concepts, and the fruit that is not obtained by treading a path. Therefore, this book contains the essence of all sutras and tantras of the Buddha's teaching, with nothing missing.
Our English translation of The Marvelous Primordial State, an ancient and extraordinary text the like of which is rarely found in the world and whose value is immeasurable, has been made for the benefit of those fortunate ones who wish to gain an understanding of the real meaning of Ati Dzogpa Chenpo. I truly hope and wish that it will serve to open the doors of their minds and engender a genuine understanding of the principle of Ati Dzogpa Chenpo.
-Chögyal Namkhai Norbu

This teaching leads directly to the level of enlightenment, therefore it does not even speak of hell.
In this teaching only omniscience exists, therefore it does not even speak of ignorance.
This is a Dharma in which one understands the real meaning without mistakes.
-The Marvelous Primordial State, Chapter 30
