Terma is the phonetic rendering of Tibetan gter-ma, from the root gter (pronounced 'ter'), meaning a treasure, a hidden thing of great value, a deposit. The ma suffix functions as a nominalizer. A terma is therefore a 'hidden treasure,' but the word's specific application within Tibetan Buddhist tradition gives it a meaning far more particular and theologically dense than any ordinary treasure. Termas are sacred teachings — texts, ritual objects, or pure experiential transmissions — said to have been concealed in rocks, caves, lakes, and statues, or within the mental continuum of specific future disciples, by the 8th-century tantric master Padmasambhava (Guru Rinpoche) and his consort Yeshe Tsogyal. The concealment was deliberate and timed: Padmasambhava allegedly recognized that certain teachings would be too advanced for the students of his own era but would be needed and properly understood in future centuries, and so sealed them in forms accessible to the future discoverers — the tertons — who were his own reincarnations or spiritual heirs.

The terma tradition divides discoveries into two categories. Earth termas (sa-gter) are physical objects or texts found in specific locations: a rock formation cracks open, a lake freezes in an unusual pattern, a cave previously invisible becomes accessible, and the terton finds the physical object — often a small scroll (shog-ser) written in a symbolic script (dakini script) that only the destined discoverer can decipher. Mind termas (dgongs-gter) are more unusual: the teaching is said to have been implanted in the terton's mental continuum by Padmasambhava in a previous life and rises spontaneously in this life as a complete, fully formed vision or revelation. Some termas are object termas and mind termas simultaneously — the physical discovery triggers the full mental revelation. The terton deciphers, transcribes, and publishes the teaching, which then enters the living religious tradition as a new text bearing Padmasambhava's authority.

The terton — the terma-discoverer — is always a recognized figure of spiritual attainment, typically a reincarnate lama whose connection to Padmasambhava can be traced through previous lives. Over the centuries of Tibetan religious history, several hundred tertons have been recognized, with the most significant discoveries producing texts that entered the Tibetan Buddhist canon alongside the classical translated scriptures. The Nyingma school, the oldest Tibetan Buddhist tradition, traces its textual authority primarily to termas rather than to the direct Indian scholarly transmission (kama) that the Sarma (new translation) schools like the Kagyu, Sakya, and Gelug emphasize. This gives the terma tradition an unusual theological function: it provides a mechanism for the renewal of revelation, allowing the Nyingma tradition to receive new authoritative texts in each generation without departing from the claim that all such texts originate with Padmasambhava in the 8th century.

The word 'terma' entered English primarily through the academic study of Tibetan religion and through the Western spread of Nyingma Buddhism. Scholars including Rene de Nebesky-Wojkowitz, Giuseppe Tucci, and later Tulku Thondup and Janet Gyatso examined the terma tradition with increasing methodological sophistication. Janet Gyatso's 1993 study 'Apparitions of the Self' offered a rigorous literary and psychological analysis of terton autobiography and vision literature that placed termas within a broader comparative framework of revealed scripture. The word now appears in religious studies literature, in comparative discussions of revelation and inspired text (alongside concepts like Christian prophecy, Islamic wahy, and Daoist revealed texts), and in popular accounts of Tibetan Buddhism. For Western practitioners of Nyingma Buddhism, the terma tradition is a living one: several contemporary Nyingma masters are recognized as tertons who continue to reveal new teachings.
