Vishishtadvaita

Ramanuja, the eleventh and twelfth century Tamil theologian who systematized Vishishtadvaita, agreed with Shankara that reality is ultimately one and that Vedanta's non-dualism is correct, but broke sharply with him over what that oneness means. Shankara's Brahman is nirguna, without attributes, and the differentiated world of souls and matter is Maya, an appearance that liberating knowledge dissolves. Ramanuja's Sri Bhashya, his commentary on the Brahma Sutras, argues at length that this reading cannot be squared with scripture's own plain sense, which repeatedly describes Brahman as possessing real, positive qualities and as genuinely related to a real world, and that calling the entire universe of ordinary experience an illusion empties devotion, ethics and scripture itself of coherent meaning. His alternative, qualified non-dualism, vishishtadvaita, holds that Brahman is one but not undifferentiated: souls and matter are Brahman's real, eternal attributes, related to it as a body's parts are related to its self, distinct in name and function yet incapable of existing apart from the whole they compose.

This body-self analogy, sharira-shariri-bhava, is the school's central technical move. Just as a person's body is entirely dependent on and controlled by that person's self, yet remains genuinely distinct from it in nature, souls and the material world are Brahman's body, wholly dependent, wholly pervaded and controlled, yet really existing as themselves rather than as illusion. The world is not something Brahman merely appears to become; it is something Brahman genuinely possesses and inhabits, which lets Ramanuja affirm non-dualism, one ultimate reality, without denying the reality of anything the world actually contains.

Vishishtadvaita is inseparable from Sri Vaishnavism, the South Indian devotional tradition Ramanuja inherited and gave philosophical form. The school calls its own method ubhaya vedanta, the twin Vedanta, because it treats the Sanskrit Upanishads and Brahma Sutras as one authoritative source and the Tamil devotional hymns of the Alvar poet-saints, collected as the Divya Prabandham, as a second, equally canonical source of the same truth, sung rather than reasoned. Ramanuja's own teaching accordingly runs on two registers at once, a rigorous scholastic philosophy defending the reality of a qualified, differentiated Brahman against Advaita, and a warm devotional theology in which Vishnu, worshipped as Narayana together with his consort Sri, is approached through prapatti, total surrender, as much as through philosophical understanding.

The school's doctrine of grace follows directly from its metaphysics. Because souls are real, dependent parts of God rather than illusory appearances destined to dissolve, their relationship to God is genuinely personal and can genuinely be marked by love, dependence and rescue rather than by the dispassionate self-knowledge Advaita prescribes. Later Sri Vaishnava teachers debated exactly how much the soul must do to secure that grace, a question later schools within the tradition answered differently, but the underlying vishishtadvaita metaphysics, one reality, really differentiated, really related as body to self, remained the fixed philosophical foundation beneath every version of that debate.
