The awareness of all sentient beings is inherently pure. It needs no refinement knows no enlightenment and cannot be an object of intellectual understanding. It is the sky-like singularity of the Bodhichitta itself. This is the Gospel of Garab Dorje the foundation of the Ati Yoga orgin story that the Tibetans have always believed. The material presented in this book is based on the conviction that Garab Dorje Manjushrimitra Sri Simha and Vairochana were real historical figures who by working together brought Ati Yoga into the world and blessed the Buddhists of Tibet with their highest teachings.
