The schools of Vedānta

Six ācāryas commented on the same three texts and reached six different conclusions. Each founded a living lineage; all six survive; none was suppressed. The disagreement is the tradition's intellectual history in concentrated form.

Advaita's central move

Śaṅkara's argument turns on adhyāsa — superimposition. We see a rope in dim light and take it for a snake; the snake was never there, and its removal is not the destruction of a snake but the ending of an error. Similarly the world of separate things is superimposed on Brahman. Note carefully: Śaṅkara does not say the world is nothing. It has vyāvahārika satya — empirical reality, fully valid at its own level — and is sublated only by the knowledge of Brahman, not by argument or by wishing.

He opens his commentary on the Brahma Sūtra not with Brahman but with this, defining the error before naming the cure — and the definition is a piece of exact analysis.

Three components, and each does work. Previously seen: nothing is fabricated from nothing — you must have met silver before to see it in the shell. In the form of memory: what is presented is not a fresh perception but a remembered content behaving as though present. In something else: the transfer requires a substrate that is actually there. Apply it to the case at issue and the substrate is the Self, which is never absent and never doubted; what is superimposed on it is the body, the senses, the mind and the world of objects. This is why Advaita denies that it makes the world unreal: an illusion needs a real ground, and the ground is the only thing Advaita ever affirms.

The middle row is the one that answers the standard objection. To say the world is māyā is not to put it in the third row. A dream is cancelled by waking up; the world is not, and no amount of philosophy will let you walk through a wall. Within the empirical order, physics is true, ethics binds, and a debt must be paid. Gauḍapāda, Śaṅkara's teacher's teacher, pushed the analysis to its limit and denied that anything is ever produced at all — a conclusion word for word parallel to Sāṅkhya Kārikā 62, reached from the opposite metaphysics.

And the whole position is compressed into a half-verse that every student learns — three clauses, each of which the other five schools would contest.

Rāmānuja's objection

Rāmānuja replies that an undifferentiated Brahman cannot be known at all, that the Upaniṣads describe Brahman with qualities as often as without, and that a doctrine of illusion makes devotion meaningless — one cannot love what one is about to discover does not exist. His alternative keeps non-duality while making the world and souls genuinely real as the body of God.

The attack is set out in the Śrī Bhāṣya as a series of untenabilities in the doctrine of avidyā, and the first three are the ones an Advaitin must answer. Where does ignorance reside? Not in Brahman, which is pure knowledge and would be contaminated; not in the individual self, which is itself produced by ignorance, so the account is circular. How can it conceal Brahman, when Brahman is self-luminous — concealing light is not a thing that can be half-done. And what is its nature, given that Advaita calls it neither real nor unreal? Rāmānuja's charge is that 'indescribable as either' is not a third option but a refusal to answer, since a thing either is or is not. The Advaitin replies that the rope-snake is precisely such a case — it cannot be real, since it vanishes; it cannot be unreal, since it was seen and caused fear — and that avidyā has Brahman for its locus without affecting it, as a rope is the locus of the snake without being coiled by it.

Rāmānuja's positive doctrine has one anchoring text, and he cites it constantly: the Antaryāmin passage, in which the whole of reality is described as the body of an indwelling Self.

The formula repeats through the passage for water, fire, the sun, the elements, the breath and finally the self, and Rāmānuja extracts a definition from it: a body is whatever is wholly supported by a self, wholly controlled by it, and exists entirely for its sake. Souls and matter stand to Brahman in exactly that relation. This lets him keep the mahāvākya intact without collapsing the terms. 'That thou art' is read as samānādhikaraṇya, co-reference: two words with different meanings pointing to one thing — as when we say 'that is the man I saw', where 'that' and 'the man' differ in sense and coincide in reference. Brahman with the soul as body, and the soul, refer to one reality. Identity of reference; difference of meaning.

Madhva's five differences

Madhva takes the opposite pole: difference is not an appearance but the very structure of reality. He names five eternal differences — between God and soul, God and matter, soul and matter, one soul and another, one material thing and another — and argues that the Upaniṣadic identity statements must be read in the light of the difference statements, not the reverse.

His method with the identity texts is grammatical rather than dismissive. He reads them as asserting dependence, not sameness: to say the soul is 'that' is to say it belongs to and subsists on that. And he leans on a verse that puts two selves in one tree and keeps them two forever.

Advaita reads the two birds as one Self appearing as enjoyer and witness. Madhva reads them as exactly what the words say — two, eternally companions, eternally distinct, one dependent and one free. He also breaks with everyone else on a point that follows from his realism: since souls differ eternally, they differ in capacity, and liberation is graded, each soul realising the bliss proper to its own nature rather than an identical state. And to explain how a partless God can have many attributes without being many things, he introduces viśeṣa — a principle of distinction-within-identity that lets a single substance sustain real internal differences. The debt to Vaiśeṣika's individuator is not accidental.

The three that keep both terms

Nimbārkasvābhāvika-bhedābheda — natural difference-and-non-difference

Difference and non-difference are both real, and neither is reducible to the other: the soul is different from Brahman as the wave is from the sea, and non-different as the wave is nothing but water. Where Śaṅkara must call one of the two an appearance, Nimbārka takes the sūtra that calls the soul a part of Brahman 'on account of the declaration of difference and also otherwise' at face value — scripture states both, so both hold.

Vallabhaśuddhādvaita — pure non-dualism

Non-dual, with the emphasis on pure: there is no māyā doing the work of concealment, and therefore no illusion to be dissolved. The world is Brahman genuinely manifest, with existence, consciousness and bliss present in matter and only the bliss withdrawn from view — a difference of manifestation, not of substance. Liberation comes by puṣṭi, grace, which cannot be earned, and the natural scripture of the school is the Bhāgavata rather than the sūtras.

Caitanya and Jīva Gosvāmīacintya-bhedābheda — inconceivable difference-and-non-difference

One and different at once, and the 'at once' is not resolved but declared inconceivable — acintya. This looks like an evasion until one sees the argument behind it: śakti, power, always stands to its possessor in a relation that defies the law of identity, as heat is neither the fire nor another thing. Brahman's energies are of that kind, so the soul, being an energy, is neither simply Brahman nor simply other.

This is the verse the last three schools use to make peace with the first. One reality, three modes of apprehension: as undifferentiated being to the seeker of knowledge, as the indwelling controller to the yogin, as the personal Lord to the devotee. Advaita is not so much refuted as ranked — its Brahman is granted to be real and said to be the least complete way of seeing what is there. Śaṅkara's heirs return the compliment exactly, treating the personal Lord as fully real at the empirical level and superseded at the absolute one. Each school makes the others true and subordinate.
