The great commentaries & Vedanta lineages: Advaita, Viśiṣṭādvaita, Dvaita

Between the 8th and 14th centuries CE, a major arena of Indian intellectual debate centered around Vedānta (“the culmination of the Vedas”). Philosophers sought to establish a comprehensive, unified theory of reality by composing exhaustive commentaries (bhāṣyas) on the Prasthānatrayī (the Triple Canon):

1. The Upaniṣads (the primary revealed texts).
2. The Bhagavad Gītā (the ethical-practical synthesis).
3. The Brahma Sūtras of Bādarāyaṇa (the systematic aphoristic dialectic).¹

This commentarial tradition produced three major schools that continue to shape Indian philosophy.

1. Advaita Vedānta: Radical Non-Dualism (Ādi Śaṅkara)

Ādi Śaṅkara (c. 8th century CE) argued that ultimate reality is non-dual, homogeneous consciousness (Brahman). A half-verse traditionally attributed to Śaṅkara summarises the position:

ब्रह्म सत्यं जगन्मिथ्या जीवो ब्रह्मैव नापरः (Brahma satyaṁ jagan mithyā jīvo brahmaiva nāparaḥ) — in substance, Brahman alone is real; the empirical world is provisionally non-absolute (mithyā); the individual soul is non-different from Brahman.²

Śaṅkara and later Advaitins addressed the apparent contradictions between the infinite Brahman and the diverse physical universe through a multi-tiered epistemic framework:

• Pāramārthika Satya (Ultimate Reality): Pure, unconditioned, non-dual consciousness beyond time, space, and causation.
• Vyāvahārika Satya (Empirical / Practical Reality): The everyday world of objects, physics, ethics, and relationships. It is not a complete void or non-entity (asat), but an experiential appearance generated by Māyā / Avidyā (cosmic cognitive projection).³
• Prātibhāsika Satya (Apparent / Illusory Reality): Optical illusions or dreams (like mistaking a coiled rope for a snake).

Liberation (Mokṣa) occurs when intuitive knowledge (Jñāna) dissolves the primal ignorance (avidyā) that misidentifies the infinite self with finite body-mind mechanisms.

2. Viśiṣṭādvaita: Qualified Non-Dualism (Rāmānuja)

Rāmānuja (c. 11th–12th century CE) launched a powerful philosophical critique against Śaṅkara’s doctrine of Māyā. He argued that an absolutely featureless, quality-less Brahman (nirguṇa) cannot be known by any valid instrument of knowledge (pramāṇa), because all knowledge reveals qualities and distinctions.⁴

Rāmānuja proposed Viśiṣṭādvaita (Qualified Non-Dualism):

• Brahman is the Supreme Divine Being (identified as Nārāyaṇa / Viṣṇu), possessing infinite auspicious attributes (saguṇa).
• The universe is an organic, inseparable whole (apṛthaksiddhi). Just as the physical human body is animated and guided by a conscious soul, the conscious souls (cit) and unconscious physical matter (acit) constitute the real “body” (śarīra) of Brahman.⁵
• The empirical world is not an illusion; it is a real, glorious manifestation of Divine reality.
• Liberation is attained through loving surrender (prapatti / bhakti) and divine grace.

3. Dvaita Vedānta: Uncompromising Dualism (Madhvācārya)

Madhvācārya (c. 13th century CE) rejected both absolute non-duality and qualified unity, formulating Dvaita (Strict Dualism / Realism):

• Reality is fundamentally characterized by an eternal, irreconcilable Five-Fold Difference (Pañca-Bheda):
  1. Difference between God (Īśvara) and individual souls (Jīva).
  2. Difference between God (Īśvara) and insentient matter (Jaḍa).
  3. Difference between individual souls and other souls (Jīva–Jīva).
  4. Difference between souls and matter (Jīva–Jaḍa).
  5. Difference between one material entity and another (Jaḍa–Jaḍa).⁶

Madhva argued that perceptual difference is fundamentally real and that individual souls retain their unique individual identity even in the state of liberation.

Comparison of the three Vedāntic models

Four terms to carry forward

What this chapter does not claim

1. That Śaṅkara viewed the physical world as nonexistent; he affirmed that the empirical world is real within the empirical sphere (vyavahāra).
2. That Rāmānuja and Madhva were merely emotional devotees; both constructed rigorous epistemological systems contesting Advaita logic.
3. That Vedānta is the only Indian philosophy; it is one of six classical orthodox schools and shared the intellectual landscape with Nyāya, Mīmāṃsā, and Jain/Buddhist traditions.
4. That these lineages were static; ongoing sub-commentaries continued to debate and refine these categories across centuries.
