Hindus believe in an uncreated, eternal, infinite, transcendent, and all-embracing principle, which, “comprising in itself being and non-being,” is the sole reality, the ultimate cause and foundation, source, and goal of all existence. This ultimate reality is called brahman. As the All, brahman causes the universe and all beings to emanate from itself, transforms itself into the universe, or assumes its appearance. Brahman is in all things and is the Self (atman) of all living beings. Brahman is the creator, preserver, or transformer and reabsorber of everything. Although it is Being in itself, without attributes and qualities and hence impersonal, it may also be conceived of as a personal high God, usually as Vishnu (Visnu) or Siva. This fundamental belief in and the essentially religious search for ultimate reality—i.e., the One that is the All—have continued almost unaltered for more than 30 centuries and have been the central focus of India's spiritual life.
