<b>A new translation of the primary Indian Buddhist text on buddha nature, with Tibetan commentaries explaining how this text can be used to contemplate and realize one's own buddha nature.</b><br><br> "Buddha nature" (<i>tathagatagarbha</i>) is the innate potential in all living beings to become a fully awakened buddha. The book gives an overview of the sutra sources of the tathagatagarbha teachings and the different ways of explaining the meaning of this term. In particular, it includes new translations of the <i>Mahayanottaratantra</i> (<i>Ratnagotravibhaga</i>), the primary Indian text on the subject, its Indian commentaries, and two (hitherto untranslated) commentaries from the Tibetan Kagyü tradition. Most important, the book investigates in detail the meditative tradition of using the <i>Mahayanottaratantra</i> as a basis for Mahamudra instructions and the Shentong approach.
