Padmasambhava Guru Rinpoche 
Light of Wisdom, Volume I [EPUB ebook] 

The Light of Wisdom Vol. I contains the root terma –hidden treasure text – of Padmasambhava, The Gradual Path of the Wisdom Essence and its commentary The Light of Wisdom by Jamgon Kongtrul the Great. Annotations on the commentary Entering the Path of Wisdom spoken by Jamyang Drakpa and recorded by Jokyab Rinpoche are included as well as clarifications from other masters.

Volume I presents in-depth explanations of the Vajrajana Buddhist perspective. It begins with the nature of the ground, the buddha nature present in all beings, continues with the teachings that are common to all vehicles, and concludes with the Mahayana and the link to Vajrayana.

This essence of the causal and resultant vehicles,

Especially the core of the realization the three sections of the inner tantras,

Linking together the ground with the path,

Makes you abandon the temporary defilements along with their tendencies,

Realize fruition and quickly accomplish the welfare of self and others,

In this way it is in conformity with each yet exalted above them all.

-Padmasambhava

The root text of Lamrim Yeshe Nyingpo, a terma revealed by the great treasure- finder Chokgyur Lingpa, and its commentary by Kongtrul Rinpoche, the great translator in person, form together a complete scripture that embodies all the tantras, statements and instructions of the Nyingma School of the early translations, which is most rare to find in the past, present, or future.
