Adibuddha
Adibuddha (S): The original Buddha, eternal with no beginning and with no end. In Mahayana Buddhism, the idea evolved, probably inspired by the monotheism of Islam, that ultimately there is only one absolute power that creates itself. He is infinite, self-created and originally revealed himself in the form of a blue flame coming out of a lotus. Over time this symbol was also personified in the form of the Adibuddha. There are various forms and manifestations in which this supreme essence of Buddhahood becomes manifest.
The First or Original Buddha. The primordial and eternal Buddha with no beginning or end. He is self-created and originally revealed himself in the form of a blue flame coming out of a lotus. Over time this symbol became personified in the form of the Adibuddha. In Tibetan Buddhism, the Adibuddha is variously referred to as Vajradhara or Samantabhadra/Samantabhadri (these being a male-female pair).
