Study the Great Perfection with the celebrated Lerab Lingpa, who imparted teachings to the Thirteenth Dalai Lama, and discover the common ground of Tibetan Buddhism’s many schools in essays by his disciples. Lerab Lingpa (1856–1926), also known as Tertön Sogyal, was one of the great Dzogchen (Great Perfection) masters of the nineteenth and early-twentieth centuries and a close confidant and guru of the Thirteenth Dalai Lama. This volume contains translations by B. Alan Wallace of two works that are representative of the lineage of this great “treasure revealer,” or tertön. The first work, composed by Lerab Lingpa himself, is The Vital Essence of Primordial Consciousness. It presents pith instructions on all the stages of the Great Perfection, which is the highest form of meditation and practice in the Nyingma school of Tibetan Buddhism. In this practice, the meditator comes to see directly the ultimate nature of consciousness itself. The work guides the reader from the common preliminaries through to the highest practices of the Great Perfection—the direct crossing over and the achievement of the rainbow body. The second work, Selected Essays on Old and New Views of the Secret Mantrayana, is a collection of seven essays by two of Lerab Lingpa’s close disciples, Dharmasara and Jé Tsultrim Zangpo.
