Vedanta: Shankara, Ramanuja, and the Nature of Brahman

Vedanta, the 'end of the Vedas,' takes the Upanishads, the Brahma Sutras, and the Bhagavad Gita as its foundational canon (prasthana-trayi) and asks how Brahman, the ultimate reality, relates to the individual self (atman) and the empirical world. Different Vedantic sub-schools answer this question in sharply divergent ways, producing one of the richest metaphysical controversies in Indian intellectual history, sustained through commentary (bhashya) on the same shared texts.

Adi Shankara's Advaita Vedanta, articulated in the 8th century, holds that Brahman alone is ultimately real (sat) and that the perceived multiplicity of the world is maya, a beginningless but ultimately unreal superimposition (adhyasa) on the non-dual Brahman. For Shankara, the individual self (jivatman) is identical with Brahman; liberation is not the acquisition of anything new but the removal of ignorance (avidya) that obscures this identity, famously expressed in the Upanishadic formula 'tat tvam asi' — 'that thou art.'

Ramanuja, writing in the 11th–12th century, rejected Shankara's illusionism and developed Vishishtadvaita, 'qualified non-dualism.' For Ramanuja, Brahman is real and is identical with the personal god Vishnu-Narayana, but the world and individual souls are real modes (prakara) or attributes of Brahman's body, not illusory appearances. Liberation, in this framework, is loving devotion (bhakti) and surrender (prapatti) to a personal deity, culminating in eternal, blissful communion rather than dissolution of individual identity.

A third major voice, Madhva, pushed further toward realism with Dvaita Vedanta, insisting on an eternal, irreducible difference between Brahman, individual souls, and matter — a position that some scholars have compared, cautiously, to later Western theistic realism. The three-cornered debate between Shankara, Ramanuja, and Madhva illustrates how a shared scriptural canon can generate radically different metaphysical and devotional outcomes depending on interpretive method.

These debates were never purely academic: Advaita's monism informed later reform movements and philosophical universalism, including aspects of Vivekananda's neo-Vedanta presented at the 1893 Parliament of Religions, while Vishishtadvaita's devotionalism shaped the Sri Vaishnava temple culture of South India and its influential textual and liturgical traditions that persist today.
