This Secret Essence Tantra is the most advanced and extensively studied tantra within the Nyingma lineage.
The twenty-two chapters of this tantra elucidate how to correctly view the ground, traverse the path, and ultimately reach the result-fully enlightened buddhahood.
The first part of this book includes the Tibetan and English translation for the root tantra itself.
The second part is a translation of the extensive commentary on The Guhyagarbha Tantra , called Thorough Dispelling of Darkness throughout the Ten Directions, written by the omniscient Longchenpa, who was an emanation of Samantabhadra.
His word-for-word commentary gives uncommon explanations regarding all stages of Vajrayana practice, including comprehensive teachings from the Dzogchen point of view on how to practice and accomplish the path to enlightenment. The author includes complete explanations of the peaceful and wrathful mandalas as well as practical instructions needed to attain the four states of vidyadharahood.
Note: Anyone interested in reading this text must have received the empowerment of Vajrasattva's Magical Manifestation Matrix for the peaceful and wrathful deities from either the kama or the terma tradition and must have received the reading transmission.
