Three schools, one set of texts, incompatible conclusions. This page sets them side by side without treating any as the default, and shows where the disagreement actually bites — which is not where popular summaries put it. The dispute is not about whether God exists. It is about what a sentence means.
⚖️ The Three at a Glance
Advaita: Shankara — non-dual; the jiva is Brahman
Vishishtadvaita: Ramanuja — Brahman qualified by selves and matter as its body
Dvaita: Madhva — five eternal differences, never collapsed
All three: commentate the same prasthana trayi under the same rules
All three: accept karma, rebirth, scripture's authority, and liberation as the goal
Not at issue: the existence of God, or the value of devotion

🗣️ One Sentence, Three Readings
The Chandogya Upanishad's tat tvam asi — “that thou art” — is where the schools can be most exactly compared, because each has to make the same three words mean something compatible with its system.
| School | Reading of tat tvam asi |
|---|---|
| Advaita | Straight identity. Tat and tvam refer to the same reality; the apparent difference (Brahman as omniscient cause, the jiva as limited) is set aside by bhaga-tyaga-lakshana, in which the incompatible parts of each term are dropped and the common referent — pure consciousness — remains. |
| Vishishtadvaita | Identity of a special kind — samanadhikaranya, co-referentiality. Both words denote the same substance because the jiva is Brahman's body; but the mode is not the substance in the way the substance is itself, so the sentence asserts inseparability, not sameness. |
| Dvaita | Madhva reads it as sa ātmā atat tvam asi — dividing the words differently, so that it says thou art not that. The reading is grammatically available in unspaced Sanskrit and is defended in his commentaries. |
🌍 The World and Error
The second real dividing line is the status of the world, and it is inseparable from each school's theory of error — because Advaita's account of the world is its account of error, generalised.
| Advaita | Vishishtadvaita | Dvaita | |
|---|---|---|---|
| The world is | Mithya — neither real nor unreal; it is experienced and is sublated on realisation | Real — the body of Brahman, a mode of him | Real and eternally distinct from Brahman |
| Rope-snake | The paradigm: something is superimposed on a substrate and vanishes on knowledge. So too the world on Brahman | Satkhyati — all cognition is of something real; the "error" involves real elements misassembled | Abhinava-anyathakhyati — error is real misapprehension, and its correction does not make the world unreal |
| Maya is | Beginningless ignorance, anirvachaniya — indescribable as either real or unreal | The Lord's real creative power; not an illusion-making faculty | The Lord's will; no doctrine of cosmic illusion |
📌 The most persistent misunderstanding
Mithya does not mean “imaginary” or “doesn't exist.” Shankara's category is deliberately a third one: neither sat (real, as Brahman is — never sublated) nor asat (unreal, as a square circle is — never experienced). The world is experienced and dependent, and its reality is borrowed. Saying “Advaita says the world is an illusion” loses precisely the distinction the term was invented to make.
🕊️ What Liberation Is
| Advaita | Vishishtadvaita | Dvaita | |
|---|---|---|---|
| Nature | Realising an identity that was always the case; nothing is attained | Attaining Vaikuntha; the soul in the Lord's likeness, with all its own perfections manifest | Attaining the Lord's presence; the soul remains itself |
| Individuality | Not retained — there was never a separate individual to retain | Retained; the soul serves eternally and is never identical | Retained, and graded: souls differ in bliss according to their intrinsic capacity |
| Means | Jnana; karma and bhakti purify and qualify but do not themselves liberate | Bhakti, and for those unable to sustain it, prapatti — surrender, available to anyone | Bhakti arising from correct knowledge, with Vayu as mediator |
| Possible while living? | Yes — jivanmukti | Generally not; liberation is on leaving the body | No |
💡 Madhva's most distinctive claim
Dvaita holds a gradation among liberated souls — ananda-taratamya. Even in release, souls differ in the degree of bliss they experience, according to their intrinsic nature. It follows from taking difference as eternal and unqualified, and it is held by no other Vedanta school. Madhva also holds a threefold classification of souls by their eventual destiny, which is likewise distinctive and which the other schools reject.
⚔️ What Each Says Against the Others
Stated as each school states it, without adjudication:
| Charge | Made by | The claim |
|---|---|---|
| Ignorance cannot be located | Ramanuja, against Advaita | Whose is avidya? Not Brahman's, being pure knowledge; not the jiva's, since the jiva is a product of it. The saptavidha anupapatti — seven untenabilities — is Ramanuja's set-piece attack |
| An attributeless Brahman cannot be spoken of | Ramanuja and Madhva | All knowledge is determinate; a wholly undifferentiated entity could not be denoted by a word or known by any means |
| Difference is directly perceived | Madhva | Difference is not inferred but given in perception; to deny it is to deny the pramana that grounds every other claim |
| Scripture's identity texts are decisive | Shankara, against both | Texts of difference operate at the level of practical reality; the identity texts are the final purport, and the six criteria of purport support them |
| Two reals cannot both be ultimate | Advaita, against Dvaita | If God and soul are both eternally real and distinct, Brahman is limited by what it is not — and a limited Brahman is not the Upanishads' Brahman |
| Advaita is disguised Buddhism | Madhva and others | Prachchhanna Bauddha — the charge that Advaita's maya doctrine reproduces Madhyamaka. Advaitins reject it, noting that Advaita affirms a positive reality where Madhyamaka does not |
❓ Frequently Asked Questions
How does each school read tat tvam asi?
Advaita: straight identity, with the incompatible parts of each term dropped by bhaga-tyaga-lakshana leaving pure consciousness as the common referent. Vishishtadvaita: samanadhikaranya — both words denote the same substance because the jiva is Brahman's body, so it asserts inseparability, not sameness. Dvaita: Madhva divides the words as sa ātmā atat tvam asi — thou art not that — a division available in unspaced Sanskrit and disputed.
Does Advaita say the world is an illusion?
Not in the way that phrase suggests. Mithya is deliberately a third category — neither sat (real as Brahman is, never sublated) nor asat (unreal as a square circle is, never experienced). The world is experienced and dependent, its reality borrowed. Calling it “an illusion” loses exactly the distinction the term was invented to make.
What is Ramanuja's main argument against Advaita?
The saptavidha anupapatti — seven untenabilities — of which the sharpest is the locus of ignorance: whose is avidya? Not Brahman's, being pure knowledge; not the jiva's, since the jiva is itself a product of it — which is circular. He also argues an attributeless Brahman cannot be spoken of, since all knowledge is determinate.
What is unique to Madhva's Dvaita?
Ananda-taratamya — a gradation among liberated souls. Even in release, souls differ in the degree of bliss they experience according to their intrinsic nature. It follows from taking difference as eternal and unqualified, and no other Vedanta school holds it. His threefold classification of souls by eventual destiny is likewise distinctive and rejected by the others.
Is one of the three schools correct?
The tradition has not settled it, and this page does not. Every argument has an answer within the school it targets, and those have counter-answers, over roughly a thousand years. What can be said accurately: three coherent, fully-developed readings of the same texts, each with living lineages, and the differences are consequential. Anyone claiming the dispute was settled is reporting a preference.
🙏 Conclusion
The three schools agree on the texts, the authority of those texts, karma, rebirth, and that liberation is the goal — and then divide on a question that sounds narrow and is not: whether “that thou art” asserts identity, inseparability, or difference. From that one point follow three different accounts of the world, of error, of what devotion is for, and of what remains of you at the end. They are not stages of one path. They are alternatives, and the tradition has never pretended otherwise.
