Mahāmudrā, “the Great Seal,” is a Sanskrit term (Tibetan: phyag rgya chen po) that connotes a wide range of concepts and practices in Indian Mahāyāna and, especially, Tibetan Buddhism, most of them directly or indirectly related to discourse on ultimate reality and the way to know and achieve it. The term first appeared in Indian tantric texts of the 7th or 8th century

As Tibetans began to import Buddhist scriptures and translate them into the Tibetan language in the 8th and 9th centuries, they also imported items like relics, reliquaries, statues, paintings, amulets, and other material objects believed to embody and transmit power through their physical connections with buddhas, bodhisattvas, and saints of the past. Guided by scriptural pronouncements, as these resonated with indigenous sensibilities Tibetans came to hold that sensory interactions with Buddhist power objects would enable unmediated access to the powerful sources of the Buddhist tradition for a range of pragmatic and transcendent goals. Such encounters were held to be so efficacious that they were sometimes promoted as viable complements or substitutes for the study and cultivation of Buddhist doctrine.
As Tibetans integrated Buddhism into Tibetan culture they began crafting their own Buddhist power objects. These became so ubiquitous and diverse in Tibetan Buddhist societies that there is no single Tibetan term that directly corresponds with the category of “power objects” to encapsulate their full range. Patterned after Indian prototypes, Tibetans developed their own terms and rubrics for these kinds of objects. They also adapted them to include a wider spectrum of items and advanced theories of their power and efficacy that extend beyond their Indian Buddhist counterparts. On this account, controversies sometimes erupted among Tibetan ecclesiastical scholars over the purported nature and potency of such things. The prominent role given to Buddhist power objects in Tibet entailed they would serve as touchstones for the formation of Tibetan Buddhist communities, institutions, and states. Yet, sustained discussion of these kinds of objects has only been sporadic among traditional Tibetan exegetes and modern academic scholars of Tibetan Buddhism.
