Fathoming the Mind: Inquiry and Insight in Dudjom Lingpa's Vajra Essence by B. Alan Wallace Bestselling author B. Alan Wallace delivers the long-awaited followup to his Stilling the Mind: Shamatha Teachings from Dudjom Lingpa’s Vajra Essence (2011). Fathoming the Mind continues the commentary to Du¨djom Lingpa’s Vajra Essence that appeared in Stilling the Mind, daringly contextualizing Buddhist teachings on the Great Perfection as a revolutionary challenge to many contemporary beliefs. This companion volume stems from an oral commentary that B. Alan Wallace gave to the next section of the Vajra Essence, on the cultivation of contemplative insight, or vipas´yana¯, that fathoms the nature of existence as a whole. Du¨djom Lingpa’s revelation consists of a fascinating dialogue that occurred during his pure vision of Samantabhadra, personification of primordial consciousness, manifesting as the youthful form of the Lake-born Vajra emanation of Padmasambhava, in dialogue with an entourage of bodhisattvas symbolizing various aspects of Du¨djom Lingpa’s mind. In continuing to reflect on Du¨djom Lingpa’s writings and their relevance to the modern world, Wallace was inspired to elaborate extensively on his original commentary. This book includes introductory essays and an afterword, which explore how the insights discussed here might contribute to yet a new “contemplative revolution,” one that would be as far-reaching in its implications as the scientific revolutions triggered by the discoveries of Galileo, Darwin, and Einstein.
