This is a modern commentary on a Dzogchen tantra titled The Natural Freedom and Openness of the Mind, covering the practices of trekcho, thogal, and bardo. This tantra is a mind terma, or treasure, of the early modern terton, or treasure revealer, Deshek Lingpa (1842-1907), and incarnation of Yudra Nyingpo, a student of Yeshe Tsogyal, preeminent female consort of Padmasambhava, through whom the transmission lineage of this teaching is said to descend. The commentary presents the approach to enlightenment taught in this tradition. These instructions are considered advanced and secret, to be taught only to those who have received transmission from a qualified master. For the curious reader outside of the tradition, this book offers a clear and concise introduction to way the Nyingma tradition frames Buddhist cosmology, mind, liberation, and prayer.
