Advaita Vedanta (IAST, Advaita Vedānta; Sanskrit: अद्वैत वेदान्त; literally, not-two) is a sub-school of Vedanta schools of Hindu philosophy and religious practice. One of the classic Indian paths to spiritual realization, Advaita postulates that the true Self, Atman, is the same as the highest Reality, Brahman. It gives "a unifying interpretation of the whole body of Upanishads", providing scriptural authority for the postulation of the non-duality of Atman and Brahman. Followers of Advaita seek liberation/release by the acquisition of vidyā (knowledge) of the identity of Atman and Brahman. It emphasizes Jivanmukti, the idea that moksha (freedom, liberation) is achievable in this life.
