Terton (Tibetan gter-ston) is a compound of gter (treasure, terma) and ston-pa (teacher, revealer, one who shows), a term also found in the name Tonpa Shenrab Miwoche, the legendary founder of the Bön religion. The terton is thus the 'treasure-teacher,' the 'revealer of hidden teachings,' the person whose spiritual lineage connection to Padmasambhava enables them to find and decode termas that were sealed specifically for them. The terton's qualifications are inseparable from the terma's authority: a terma discovered by someone who is not its designated terton is considered invalid or inaccessible, and there are Tibetan accounts of unauthorized individuals attempting to open terma sites and being met with obstacles, failure, or even spiritual danger. The system is self-regulating: only the right person at the right time can open the right terma.

The biography of a terton typically follows a recognizable pattern. In childhood or early adulthood, the future terton experiences visions, hears teachings in dreams, or encounters prophetic texts describing their destined discoveries. A senior lama — often the Karmapa, Dalai Lama, or another figure of high authority — confirms the signs and the destiny. The terton then enters practice, receives initiations that activate the relevant karmic connections, and eventually discovers the terma: finding a physical object in a rock or lake, transcribing a text that appears spontaneously in their mind, or — in the case of object termas — deciphering a small scroll written in the symbolic dakini script. The terton then transmits the teaching to qualified disciples, who preserve it and transmit it in turn, creating a new branch of the living practice tradition.

The greatest tertons in Tibetan history are celebrated figures whose discoveries transformed the religious culture of their periods. Nyangrel Nyima Özer (1124–1192) discovered some of the earliest major termas, including important Guru Rinpoche hagiographies. Pema Lingpa (1450–1521) discovered termas in the lakes of Bhutan, reportedly pulling golden caskets from the water in front of witnesses. Jamyang Khyentse Wangpo (1820–1892) was one of the central figures of the Rimé ('non-sectarian') movement, which used terma texts as a vehicle for ecumenical synthesis across Tibetan Buddhist schools. Dudjom Rinpoche (1904–1987), recognized as the last great terton of the pre-diaspora period, produced terma texts and scholarly compilations that became foundational documents for Nyingma Buddhism in exile. Each of these figures is understood not as an independent religious innovator but as a vehicle through which Padmasambhava's 8th-century teachings reached their appropriate future audiences.

The word 'terton' entered English through Tibetan Buddhist studies and the Western spread of Nyingma Buddhism, and it is now used without translation in academic and practitioner literature on Tibetan religion. The terton tradition invites comparison with other traditions of revealed scripture and prophetic inspiration — the Daoist tradition of revealed texts (lingbao scriptures), the Islamic understanding of the Prophet as receiver of revelation, the Latter-day Saint concept of the prophet receiving new scripture through divine agency — and these comparisons have been pursued in comparative religion scholarship. What is distinctive about the terton is the combination of reincarnation doctrine, specific named concealment events, and testable recognition procedures: the terma tradition is, at least in principle, empirically grounded in a way that many revealed scripture traditions are not.
