In Vajrayana Buddhism, the Ādi-Buddha () is the "First Buddha" or the "Primordial Buddha". Another common term for this figure is Dharmakāya Buddha. The term emerges in tantric Buddhist literature, most prominently in the Kalachakra. "Ādi" means "first", such that the Ādibuddha was the first to attain Buddhahood. "Ādi" can also mean "primordial", not referring to a person but to an innate wisdom that is present in all sentient beings. In Indo-Tibetan Buddhism In Indo-Tibetan Buddhism, the term Ādibuddha is often used to describe the Buddha Samantabhadra (in Nyingma), Vajradhara or Kalachakra (in the Sarma schools). There was also a tradition in India which saw Mañjuśrī as the Ādibuddha, as exemplified by Vilāsavajra's commentary to the Mañjuśrīnāmasamgīti. Vilāsavajra states in his commentary: The gnosis-being Mañjuśrī is not the bodhisattva who is the master of the ten stages (bhumi). Rather, he is the non-dual gnosis (advayajñāna), the perfection of wisdom (prajñāpāramitā) itself. According to Anthony Tribe, this tradition may have influenced the Jñānapāda tradition of Guhyasamāja exegesis, which places Mañjuvajra (a tantric form of Mañjuśrī) at the center of the Guhyasamāja mandala. In the Nyingma (Ancient) School In the Nyingma School, the Adi-Buddha is called Samantabhadra (Skt.; Tib. ཀུན་ཏུ་བཟང་པོ་, Kuntu Zangpo; Wyl. kun tu bzang po). Nyingma art often depicts this figure as a naked blue Buddha. According to Dzogchen Ponlop: The color blue symbolizes the expansive, unchanging quality of space, which is the ground of all arisings, the basis of all appearances, and the source of all phenomena. The absence of robes symbolizes the genuine reality beyond any dualistic, conceptual, or philosophical clothing. That is the dharmakaya buddha: the genuine body of absolute truth. According to Jim Valby (a translator of the Kunjed Gyalpo Tantra), in the Nyingma school's Dzogchen tradition, Samantabhadra ("All-Good") is not a God but "our timeless Pure Perfect Presence beyond cause and effect." In Nyingma, Samantabhadra is also considered to be the source of all Dzogchen teachings. The Kunjed Gyalpo Tantra calls Samantabhadra the "All-Creating King" (Tib. Kunjed Gyalpo), because all phenomena are said to be manifestations or displays of Samantabhadra. According to Namkhai Norbu, this does not mean there is some being called Samantabhadra that creates the universe, instead what it refers to is that all things arise from "the state of consciousness Samantabhadra, the state of Dharmakaya." In this sense, Samantabhadra is seen as being a symbolic personification of the ground or basis (ghzi)
