A set of commentaries that present some of the most rarefied and secret teachings within Tibetan Buddhism from the perspective of the Dalai Lama's Gelug school. The Blazing Inner Fire of Bliss and Emptiness presents lucid translations of a pair of detailed commentaries by the famed Tibetan tantric master Ngulchu Dharmabhadra (1772-1851), illuminating a set of extremely secret and restricted tantric practices of highest yoga tantra. The first of these commentaries details the practices of the Six Yogas of Naropa, one of the most celebrated and revered systems of completion-stage practice in Tibet. Dharmabhadra presents the Six Yogas by elaborating upon Lama Tsongkhapa's (1357-1419) masterpiece on the subject entitled Endowed with the Three Inspirations, which served as the basis for nearly all subsequent commentaries on the Six Yogas within the Gelug tradition. Ngulchu Dharmabhadra's commentary is unique in that it presents the Six Yogas within the context of Vajrayogini practice, making this book a perfect companion piece to The Extremely Secret Dakini of Naropa (Wisdom Publications, 2020). Also contained in this book is Ngulchu Dharmabhadra's lucid and concise commentary on the First Panchen Lama's (1570-1662) famous Supplication for Liberation from [Fear of] the Perilous Journey of the Intermediate State. The prayer--a beautiful literary contribution from the First Panchen Lama in its own right--invokes the immediacy of death and the potential to use the process of dying as an opportunity for liberation. The prayer extols the efficacy of the "nine mixings" of the completion stage as direct means of transforming our ordinary death process by using advanced yogas presented in the first commentary on the Six Yogas. Together, these works present the reader with a vast and profound vision of spiritual transformation--one in which every aspect of human experience can be used as an opportunity for transcendence and spiritual liberation.
