Vishishtadvaita (Sanskrit: विशिष्टाद्वैत, “qualified non-dualism”) is a school of Vedanta philosophy associated primarily with the South Indian theologian Ramanuja (c. 1017-1137 CE). It holds that ultimate reality (Brahman) is a single, unified whole, but that this whole is internally differentiated - comprising the personal God Vishnu (identified with Brahman), individual souls (jivas), and the material world (prakriti), the latter two serving as the “body” of God. This distinguishes it from Advaita Vedanta, which denies any ultimate distinction between Brahman and the individual self, and from Dvaita Vedanta, which asserts a permanent ontological separation between God, souls, and matter.

Vishishtadvaita is rooted in the devotional tradition of the Alvars, Tamil poet-saints whose hymns (collected as the Divya Prabandha) expressed intense personal love for Vishnu. Ramanuja systematized this devotional tradition into a rigorous philosophical framework, drawing on the Upanishads, the Brahma Sutras, and the Bhagavad Gita - the canonical “three sources” (prasthanatrayi) of Vedanta - as well as on earlier thinkers in the Sri Vaishnava lineage, including Nathamuni and Yamuna. The school is the philosophical foundation of Sri Vaishnavism, one of the principal Vaishnava traditions of South India. For a fuller account, see Vishishtadvaita - History.

The central metaphysical claim of Vishishtadvaita is that Brahman (God, identified as Vishnu or Narayana) is the only independent reality, but possesses souls and matter as inseparable attributes or “modes” (prakara). Individual souls are real and eternally distinct from one another and from God, yet they have no existence independent of God - a relationship Ramanuja describes using the analogy of body and soul. This position is intended to preserve both the strict unity of Brahman (against dualist readings) and the reality of the individual soul and world (against the strict non-dualism of Advaita).

Liberation (moksha) in Vishishtadvaita consists not in the dissolution of the individual self into an undifferentiated Absolute, but in the soul's eternal, conscious participation in the life of God - a state of perfect knowledge and bliss in which the soul's individuality is preserved. The primary means to liberation is bhakti (devotion), understood as a sustained, loving contemplation of God, though prapatti (self-surrender or grace-reliance) is also recognized, and became the dominant soteriological emphasis in the later Tenkalai sub-school.

Following Ramanuja, the Sri Vaishnava tradition split into two sub-schools, the Vadakalai and the Tenkalai, differing primarily on the role of human effort versus divine grace in liberation, and on the authority of Sanskrit versus Tamil scriptures. These debates have continued within the tradition to the present day.

Vishishtadvaita is one of the three major Vedanta schools, alongside Advaita (associated with Adi Shankaracharya, c. 8th century CE) and Dvaita (associated with Madhvacharya, c. 13th century CE). All three accept the authority of the prasthanatrayi but interpret its texts differently, particularly on the nature of Brahman, the self, and their relationship. The debates among these schools constitute a central strand of classical Indian philosophy. See Vedanta - Debate for a structured account of the major points of contention.

Like other classical Indian philosophical schools, Vishishtadvaita operates within a cosmological framework derived from Sanskrit texts that predate modern astronomy. Interpreting the cosmological content of these texts - including questions of heliocentrism, the age of the universe, and the structure of the cosmos - in light of contemporary science is an ongoing area of discussion within Hindu philosophical and religious communities. See Heliocentrism - Hindu Viewpoint for relevant context.

• Advaita Critique - Advaitins, following Shankaracharya, argue that Vishishtadvaita fails to escape dualism and misreads the Upanishadic equation of Atman and Brahman.
• Dvaita Critique - Dvaitins, following Madhvacharya, hold that Vishishtadvaita insufficiently distinguishes God from souls and matter, and that permanent ontological difference is essential to genuine devotion.
• Sri Vaishnava Defense - Within the tradition, Vishishtadvaita is held to be the correct reading of the prasthanatrayi, uniquely reconciling scriptural texts on unity and difference.
• Comparative Philosophy - Some philosophers have explored structural parallels between Vishishtadvaita and Western panentheism or process theology, though the extent of genuine conceptual overlap is disputed.
