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.
It’s a result of 10 years of work of Elio Guarisco, Adriano Clemente and Jim Valby, who translated the text consulting Chögyal Namkhai Norbu. It’s now available.
