arhat

One who has attained enlightenment; a Buddhist saint.

1954: Over and against the arhat, retreating from appearances into an entirely transcendental Nirvana, stands the Bodhisattva, for whom Suchness and the world of contingencies are one — Aldous Huxley, The Doors of Perception (Chatto & Windus 1954, p. 32)

One of the stages of the ascetic's spiritual evolution, when all passions (anger, ego, deception, greed, attachment, hatred and ignorance) are destroyed.
