Vishishtadvaita Vedanta (IAST Viśiṣṭādvaita Vedānta; Sanskrit: विशिष्टाद्वैत) is a sub-school of the Vedanta (literally, end or the goal of knowledge, Sanskrit) school of Hindu philosophy, the other major sub-schools of Vedānta being Advaita, Dvaita, and Achintya-Bheda-Abheda. VishishtAdvaita (literally "Advaita with uniqueness; qualifications") is a non-dualistic school of Vedanta philosophy. It is non-dualism of the qualified whole, in which Brahman alone exists, but is characterised by multiplicity. It can be described as qualified monism or qualified nondualism or attributive monism.
