Brahman (Devanāgarī: ब्रह्मन् bráhman) is the eternal and transcendent reality that exists in all matter, energy, time, space, being, and everything in the Universe. Brahman is also described as Satchitananda ("Truth-Consciousness-Bliss"). Brahman is the source and essence of the material universe. In the Taittiriya Upanishad Brahman is described as satyam jnanam anantam brahman ("Brahman is of the nature of truth, knowledge and infinity").
The goal of Vedanta is to realize that the Atman is a microcosm, and is a part of the macrocosm, Brahman - "ekam sat" ("Truth is one"), and "All paths lead to the one Truth, though many sages [and religions] call upon it by different names."
