"In this authoritative translation of key texts of Everlasting Bèon, Marc des Jardins opens up a relatively unknown tradition, which since the arrival of Buddhism in Tibet has undergone great transformations in its philosophy, doctrinal teachings, and meditative practices. The five texts each represent an important aspect of the tradition. The first text by Drogèon Azha Lodrèo Gyaltsen (1198-1263) presents the grounds and paths of the Greater Vehicle of the Bèon tradition and represents the philosophical ideology of its teachings based on the scriptures contained in the Bèon canon. The second text is a short root tantra attributed to revealed teachings from Kuntu Zangpo, the personification of the unconditioned absolute. The third text is a commentary on this root tantra attributed to Drenpa Namkha (fl. eighth century), a Bèonpo sage contemporary with Padmasambhava. The fourth text by Nyamâe Sherap Gyaltsen (1356-1415) presents a general exposition of the tantric system according to Yungdrung Bèon. The final text by Drutèon Gyalwa Yungdrung (1242-90) pertains to the oral instructions on the meditation practices of Bèon, especially on the cycle of practices associated with experiencing the nature of the mind, the Great Perfection systems. All five texts have been selected by the late H. H. Menri Trizin Rinpochâe, Lungtok Tenpai Nyima (1927-2017), who was the thirty-third abbot of Menri Monastery, the central institution of the Yungdrung Bèon school"--
