Vedānta — the enquiry into Brahman

Vedānta is the end of the Veda in both senses — its last portion, and its conclusion. Its question is single: what is the relation between Brahman, the individual self, and the world? Every school of Vedānta is one answer to that question, defended by commentary on the same three texts.

The three foundations

A man is not counted a founder of a Vedānta school until he has commented on all three. That single convention is why the disagreements are so exact: six ācāryas, the same corpus, no freedom to select convenient texts, and every awkward verse to be accounted for in public.

The catuḥsūtrī — four aphorisms that contain the whole system

The Brahma Sūtra runs to 555 aphorisms, but the tradition treats the first four as a unit and calls them the catuḥsūtrī. Every commentator writes his longest and most personal pages here, because whoever controls the reading of these four controls the reading of the rest.

Both words are contested, and the contest is the first fork in the road. Ataḥ — 'therefore' — means the enquiry follows on something. Śaṅkara says it follows on the fourfold qualification: the discrimination of the eternal from the non-eternal, dispassion towards enjoyment here and hereafter, the six disciplines beginning with calm, and the longing for release. Rāmānuja says it follows on the study of the ritual portion, so that the two Mīmāṁsās form one continuous enquiry and Jaimini's work is the necessary preliminary rather than a discarded stage. Everything about how the two schools treat ritual is already implicit in that one word.

Three words, and they are a definition of Brahman by its effect: Brahman is that from which the birth, the continuance and the dissolution of this world proceed. The sūtra deliberately does not say 'that which made this'. It says 'that from which' — the ablative that will later carry the doctrine that Brahman is the material of the world and not merely its maker. And 'origin and the rest' packs in the other two: what a thing came out of, is sustained by, and returns into, is one and the same.

A compound that can be dissolved two ways, and the commentators exploit both. Read as 'that of which scripture is the source', it says Brahman is known only from revelation — inference cannot reach it, since Brahman has no perceptible mark from which to argue, and the previous sūtra's definition would otherwise be a mere inference from the world to a maker. Read as 'that which is the source of scripture', it says the Veda proceeds from Brahman — and Śaṅkara notes that a being from whom a work of that magnitude issues without effort, as breath issues from a man, is thereby shown to be of unlimited knowledge. Both readings are given; neither is discarded.

The tu — 'but' — is answering an objection, and the objection is Mīmāṁsā's. Jaimini's school holds that scripture is authoritative only where it enjoins an action; a sentence about an existing thing has nothing to command and therefore no work to do. Bādarāyaṇa's reply is samanvaya: the Upaniṣadic texts are, on a proper application of the marks of purport, about Brahman — that is what they are for, and their validity does not depend on being convertible into a command. Śaṅkara presses further: knowledge of an existing fact cannot be enjoined at all. One can be told to sacrifice; one cannot be told to see the rope as a rope. When the rope is seen, the snake goes, whether or not anyone was ordered to look. With that argument Vedānta separates itself from Pūrva Mīmāṁsā and becomes an independent system.

The great sentences

The third is the most fought over, and it is worth seeing in place. Uddālaka has spent the whole sixth chapter of the Chāndogya teaching his son that everything is a modification of one being, and he ends nine successive sections with the same sentence.

Brahman is what the world is made of

The distinctive Vedāntic claim is not that God made the world but that there was nothing else for Him to make it out of. The argument is anchored in an image Uddālaka gives at the start of the same chapter, and Bādarāyaṇa cites it by name.

Note what is being reasoned from: a word. Uddālaka's promise was that by knowing one thing, everything made of it is known — and that promise is only kept if the effect is not a second thing over and above the cause. A pot is not clay plus something; it is clay in a shape, and the shape is 'a matter of speech, a name'. Hence non-difference. This one sūtra is the seed of the entire quarrel between the schools, because it says the effect is non-different from the cause without saying in what sense. Advaita takes it as vivarta — appearance, the cause not really changing at all. Viśiṣṭādvaita and the rest take it as pariṇāma — real transformation, the cause genuinely becoming. Neither reading is a strain on the words.

Three images, and the tradition chose them carefully. The spider supplies the thread from its own body and takes it back — material and efficient cause in one being. The earth does not decide to grow plants — production without deliberation. Hair grows from a person without diminishing him — the source is not consumed. A potter would have been the obvious image, and it is precisely the image the Upaniṣad declines to use, because a potter is external to his clay.

Two descriptions of Brahman, and the sūtra that forces a choice

Scripture describes Brahman in two incompatible registers. It defines it positively —

— and it withdraws every description offered, in Yājñavalkya's formula:

Even the positive definition is read by Śaṅkara as three negations in disguise: real excludes change, consciousness excludes inertness, infinite excludes limit — so the sentence tells you what Brahman is not, three times, without ever placing it in a class. Bādarāyaṇa then rules on the conflict, and his ruling is the hinge on which the schools turn.

Śaṅkara reads it as settling the matter for the formless: Brahman has no second nature, no form-bearing aspect residing anywhere; the descriptions with qualities are concessions to worship. Rāmānuja reads exactly the same words the other way: what is denied is that Brahman has any defective quality anywhere; the negations remove imperfection, not attribute. The whole of Vedāntic history is in that disagreement, and it is a disagreement about grammar as much as about God.

Why the world is unfair, if Brahman made it

The objection is put in the sūtras themselves, at full strength: a being who creates beings of unequal fortune, and creates them into suffering, is partial and cruel. Two consecutive aphorisms answer it.

The first disposes of the question 'why did a complete being create at all?' — not from need, since a being lacking nothing can act only as one acts in play. The second answers the harder charge. Brahman's dispensation is sāpekṣa, dependent: it takes into account the merit and demerit that beings bring with them. And the next sūtra blocks the obvious rejoinder — that before the first creation there was no karma to take into account — by denying there was a first creation: the series of world-cycles is beginningless, as beginningless as the seed and the sprout, so at no point is there a moment when Brahman allotted conditions arbitrarily. Whether that is a solution or a deferral is a fair question. It is at any rate a stated argument, offered in public, with the objection preserved beside it.

The common ground

• Brahman is the cause of the world — its material and efficient cause together.
• The Upaniṣads are the authority on Brahman, since perception and inference cannot reach it.
• The self is not the body; suffering arises from ignorance of what one is.
• Liberation comes through knowledge, however each school defines knowledge.

Where they divide

On the status of the world and of the individual soul. Is the world real, unreal, or real-but-dependent? Is the soul identical to Brahman, a part of it, or eternally distinct? These are the questions that produce Advaita, Viśiṣṭādvaita, Dvaita and the rest — and the disagreement is technical, sustained and honest.

The last aphorism of the whole work states the one thing they all agree on, and states it twice — the doubling being the traditional mark that a treatise has ended.
