Terma (Tibetan: གཏེར་མ་, Wylie: gter ma; "hidden treasure") are various forms of hidden teachings that are key to Vajrayana or Tibetan Buddhist and Bon religious traditions. The belief is that these teachings were originally esoterically hidden by various adepts such as Padmasambhava and dakini such as Yeshe Tsogyal (consorts) during the 8th century, for future discovery at auspicious times by other adepts, who are known as tertöns. As such, terma represent a tradition of continuous revelation in Vajrayana or Tibetan Buddhism. Termas are a part of tantric literature.
