Vishishtadvaita
Vishishtadvaita Vedanta (IAST Viśiṣṭādvaita Vedānta; Sanskrit: विशिष्टाद्वैत), the philosophy of the Sri Sampradaya, 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, "Dvaitadvaita" 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 characterized by multiplicity. It can be described as qualified monism or qualified non-dualism or attributive monism.
It is a school of Vedanta philosophy which believes in all diversity subsuming to an underlying unity. Ramanuja, the main proponent of Vishishtadvaita philosophy contends that the Prasthana Traya ("The three courses"), namely the Upanishads, the Bhagavad Gita, and the Brahma Sutras are to be interpreted in a way that shows this unity in diversity, for any other way would violate their consistency.
