Brahman

Brahman (nominative brahma ब्रह्म) is the concept of the supreme spirit found in Hinduism. Brahman is the unchanging, infinite, immanent, and transcendent reality which is the Divine Ground of all matter, energy, time, space, being, and everything beyond in this universe. The nature of Brahman is described as transpersonal, personal and impersonal by different philosophical schools. In the Rig Veda, Brahman gives rise to the primordial being Hiranyagarbha that is equated with the creator God Brahmā. The trimurti can thus be considered a personification of hiranyagarbha as the active principle behind the phenomena of the universe. The seers who inspired the composition of the Upanisads asserted that the liberated soul (jivanmukta) has realized his identity with Brahman as his true self (see Atman).

The word "Brahman" is derived from the verb brh (Sanskrit:to grow), and connotes greatness. The Mundaka Upanishad says:

Om. That supreme Brahman is infinite, and this conditioned Brahman is infinite. The infinite proceeds from infinite. Then through knowledge, realizing the infinitude of the infinite, it remains as infinite alone.
