Maitreya

n. (Buddhism) Buddha anticipated to come to our world to teach Buddhist law

Maitreya Bodhisattva (Sanskrit) or Metteyya Bodhisatta (Pāli) is a future Buddha of this world in Buddhist eschatology. Maitreya is a Bodhisattva who in the Buddhist tradition is to appear on Earth, achieve complete enlightenment, and teach the pure Dharma. Maitreya Bodhisattva will be a successor of the historic Śākyamuni Buddha. The prophecy of the arrival of Maitreya is found in the canonical literature of all Buddhist sects (Theravāda, Mahāyāna, and Vajrayāna) and is accepted by most Buddhists as a statement about an actual event that will take place in the distant future.
