Terma (religion)
Terma (Tibetan: གཏེར་མ་, Wylie: gter ma; "hidden treasure") are key Tibetan Buddhist and Bön teachings, which the tradition holds were originally esoterically hidden by various adepts such as Padmasambhava and his consorts in the 8th century for future discovery at auspicious times by other adepts, known as tertöns. As such, they represent a tradition of continuing revelation in Buddhism. The majority of terma teachings are tantric in nature, although there are notable exceptions.
