Adhyāya I — Samanvaya

Now, therefore, the enquiry into Brahman

MeaningNow, therefore, the enquiry into Brahman (is to be undertaken).

ExplanationThe opening word atha does not mean “after ritual” or “after studying the Pūrva-mīmāṃsā”, says Śaṅkara, but “after acquiring the fourfold fitness”: discrimination of the lasting from the passing, dispassion towards rewards here and hereafter, the six inner disciplines beginning with calm and self-control, and a real longing for freedom. Ataḥ, “therefore”, gives the reason: the Veda itself shows that whatever is gained by action ends, while knowledge of Brahman brings the highest good. A “desire to know” is named rather than knowledge because one cannot command knowledge; one can only enquire until it dawns.

Philosophical aspectThe whole system rests on this sūtra’s claim that liberation is a matter of knowing, not doing. Brahman is not something to be produced, reached or purified; it is to be known, and since it is one’s own Self it is already present — what is missing is only the clear understanding. Śaṅkara prefaces this sūtra with his famous adhyāsa-bhāṣya: the mixing-up of the Self and the not-self is the root of all suffering, and the enquiry exists to undo it.

Other schoolsRāmānuja takes atha as “after the enquiry into ritual (karma-vicāra)”: the two Mīmāṃsās are one continuous śāstra, and knowledge of works shows their limits. Madhva reads atha as auspicious and also as “after fitness”, and stresses that the enquiry is into Viṣṇu, the Brahman of all the Vedas.

Brahman is that from which the world arises

Meaning(Brahman is that) from which the origin, sustenance and dissolution of this (world) proceed.

ExplanationThe sūtra points to Taittirīya Upaniṣad 3.1, where Varuṇa tells his son Bhṛgu: “That from which these beings are born, by which they live, and into which they return — seek to know that; that is Brahman.” A world so ordered — with countless agents, places, times and causes fitting together — cannot come from an unconscious source or from chance; it must come from an all-knowing and all-powerful cause. But the sūtra does not ask us to infer Brahman: it is pointing to what the Upaniṣad declares.

Philosophical aspectThis is the taṭastha-lakṣaṇa, a definition “standing at the edge”: like pointing out a house by the crow sitting on its roof, it indicates Brahman through the world, which is not part of Brahman’s nature. The essential definition (svarūpa-lakṣaṇa) is satyaṃ jñānam anantaṃ brahma — existence, consciousness, infinitude. Being the cause, Brahman is both the material and the efficient cause, as 1.4.23 will prove.

Other schoolsFor Rāmānuja and Madhva the definition is not merely “pointing”: creating, sustaining and dissolving the world are real glories of Brahman (Nārāyaṇa / Viṣṇu), and the sūtra describes a God who truly possesses them.

Known only through scripture — and its source

MeaningBecause (Brahman) is the source of the scripture — and because scripture is the means of knowing it.

ExplanationŚaṅkara gives two readings. First: Brahman is the source of the vast Veda, which illumines all things like a lamp; the author of such a body of knowledge must be omniscient. Second: the scripture is the yoni, the valid means, through which alone Brahman is known. Perception cannot reach it, since it is not an object; inference cannot establish it, for inference needs an observed link between sign and thing, and Brahman is one without a second. Reason has a role, but it supports the meaning of the Upaniṣads; it does not replace them.

Philosophical aspectVedānta here takes a stand in epistemology. The Self is self-evident but its nature as Brahman is not; that identity is something no other pramāṇa could reveal. Hence the teaching is called śabda-pramāṇa: words used by a teacher, rightly understood, can remove ignorance about what is already one’s own Self.

Other schoolsAll the schools agree that Brahman is known from śāstra; Madhva stresses the second reading so that no reasoning independent of the Veda can establish God.

All the Upaniṣads have one purport

MeaningBut that (Brahman is known from the Upaniṣads), because it is their uniform purport.

ExplanationThe Mīmāṃsaka objects: the Veda exists to command action, so passages describing an existing thing can only praise or support some act — knowledge of Brahman must serve a meditation or ritual. Bādarāyaṇa answers with tu: when the Upaniṣads are read with the six marks of purport (beginning and end, repetition, novelty, result, praise and reasoning), they are seen to aim at Brahman, the Self, as their main subject. Knowledge of an existing thing depends on the thing, not on the knower’s will, so it cannot be enjoined. And its fruit — freedom — is immediate, not produced later.

Philosophical aspectŚaṅkara’s long commentary here is the heart of Advaita: liberation (mokṣa) is eternal, so it cannot be a product of action; it is the very nature of the Self, revealed when ignorance is removed. “You are That” is not a command to meditate but a statement of fact. The rest of the Brahma Sūtra applies this one sūtra to text after text.

Other schoolsRāmānuja accepts that Brahman is the purport but holds that the knowledge which liberates is a steady loving meditation (dhyāna, upāsanā) culminating in direct vision, and so it can be enjoined. Madhva also makes knowledge an enjoined meditation on Viṣṇu, rewarded by his grace.

The cause thought — so it is not unconscious matter

MeaningThe pradhāna, which has no scriptural basis, is not (the cause of the world), because (the cause is said) to have thought.

ExplanationChāndogya 6.2.3 says: “It thought: may I be many, may I be born.” Only a conscious being thinks. The Sāṅkhya teachers held that the world comes from pradhāna, the unconscious equilibrium of the three guṇas, and claimed Upaniṣadic support. Bādarāyaṇa answers that “thinking” cannot be applied to an unconscious principle except figuratively, and the next sūtras show it is meant literally, since the same “being” is called the Self and liberation comes from devotion to it.

Philosophical aspectThis is the first of the many refutations of Sāṅkhya. The issue is not technical: if the root of the world is unconscious, consciousness is a stranger in it; if the root is conscious, the world is an expression of that consciousness. Vedānta affirms the second.

The self “made of bliss”

MeaningThe one consisting of bliss (is the supreme Self), because of repetition.

ExplanationIn the Taittirīya’s series of selves — of food, vital air, mind, understanding and bliss — is the last, the “self made of bliss”, Brahman itself? This sūtra and the next seven give the older view that it is. Śaṅkara, unusually, explains them and then reinterprets: -maya means “modification”, and the bliss-sheath has joy as its head, delight as its sides — parts that cannot belong to the partless. The Brahman meant is the one named just after it, “Brahman is the tail, the support”.

Philosophical aspectThis becomes the classical doctrine of the five sheaths (pañca-kośa): the Self is not any sheath, even the subtlest bliss of deep sleep; it is the support of all of them. The aim is not a blissful state but recognition of the Self that shines through every state.

Other schoolsRāmānuja and Madhva keep the straightforward reading: the self made of bliss is the supreme Lord, full of bliss.

The golden person within the sun

MeaningThe one within (the sun and the eye is Brahman), because its qualities are taught.

ExplanationChāndogya 1.6 describes a golden person seen in the sun, with golden beard and hair, and a person seen in the eye. Is this a superior soul or a deity? The sūtra says Brahman, because the passage gives him qualities only Brahman has: he is “risen above all evil” and is the lord of all worlds and desires. The form is assumed for the sake of meditation.

Philosophical aspectA pattern is set here for the whole first chapter: wherever a text speaks of some being with unmistakable marks of Brahman — freedom from evil, rulership of all, being the Self of all — it is Brahman, however it is pictured.

“Space” here means Brahman

Meaning“Space” (here is Brahman), because of its marks.

ExplanationChāndogya 1.9.1: “All these beings arise from space alone and return to space; space is greater than all, space is the final goal.” Elemental space cannot be the source of all beings, since it is itself created. Being the origin and goal of all is Brahman’s mark, so “space” here is a name for Brahman — fitting, since Brahman, like space, is all-pervading, subtle and unattached.

Philosophical aspectThe Upaniṣads use the names of elements and forces as windows onto Brahman. The rule: the meaning of a word is fixed by the marks (liṅga) given in the passage, not by the word’s everyday sense.

“Prāṇa” here means Brahman

MeaningFor the same reason, “prāṇa” (is Brahman).

ExplanationIn Chāndogya 1.11.5 the priest is told that all beings enter into prāṇa and rise from it. The life-breath of living things cannot be what all beings, including the inanimate, return to, so prāṇa here is Brahman. The same reasoning as for space applies.

Philosophical aspectPrāṇa is a favourite Upaniṣadic symbol because it seems to be what keeps us alive; the sūtra lifts it from the physiological to the absolute — the real “life” of everything is Brahman.

The light beyond heaven

MeaningThe light (is Brahman), because (its) feet are mentioned.

ExplanationChāndogya 3.13.7 speaks of “the light that shines beyond this heaven, on the backs of all, in the highest worlds” — and identifies it with the light within a person. Is this physical light? No: the preceding verse (3.12.6) speaks of Brahman with four feet, of which all beings are one foot and three are immortal in heaven; the “light beyond heaven” is that same Brahman.

Philosophical aspectContext governs meaning: a passage is read with what precedes and follows. Brahman is “the light of lights”, the consciousness by which even the sun is known.

Indra says “Know me” — speaking as the Self

MeaningBut the teaching (of Indra, “Know me”) is from the standpoint of scripture, as with Vāmadeva.

ExplanationIn the Kauṣītaki Upaniṣad Indra tells Pratardana: “I am prāṇa, the conscious self; meditate on me.” How can a god say this? Because Indra speaks from the realised vision of identity with Brahman taught in scripture, just as the sage Vāmadeva, on realising Brahman, declared “I was Manu, I was the sun” (Bṛhadāraṇyaka 1.4.10).

Philosophical aspectA key Advaitic text: one who knows Brahman can rightly say “I am all”, because the “I” has been understood as Brahman. Statements of the knower are not boasts but descriptions of the Self.

Other schoolsRāmānuja: Indra speaks of the Lord who is his inner Self, as the body may be named by the name of its soul.

The one made of mind is Brahman

Meaning(The one consisting of mind is Brahman), because what is well known everywhere (as Brahman) is taught (here).

ExplanationThe Śāṇḍilya-vidyā (Chāndogya 3.14) begins “All this is Brahman” and then asks one to meditate on “the one made of mind, whose body is prāṇa, whose form is light, whose resolve is true”. Is this the individual soul? No — the passage begins with Brahman, well known throughout the Upaniṣads, and the qualities fit Brahman, presented with attributes for meditation.

Philosophical aspectThis pāda deals with passages whose marks of Brahman are less clear (aspaṣṭa). The second pāda thus teaches the reader to see Brahman beneath descriptions that seem to fit a limited being.

The eater whose food is the whole world

MeaningThe eater (is Brahman), because the moving and unmoving are taken (as food).

ExplanationKaṭha 1.2.25 speaks of one for whom the brāhmaṇa and the kṣatriya are food and death is the condiment. Who is this eater — fire, the soul, or Brahman? Only Brahman, into which the whole world of moving and unmoving things dissolves, “eats” everything; death itself is just the sauce.

Philosophical aspectAn image of dissolution (pralaya): Brahman is not only the source but also the end of all. Even death, the great devourer, is devoured.

The two in the cave of the heart

MeaningThe two who have entered the cave are the two selves, for that is seen (in scripture).

ExplanationKaṭha 1.3.1 speaks of two “drinking the truth” who have entered the cave of the heart, like shade and sunlight. Are they intellect and soul? The sūtra says they are the individual self and the supreme Self — both conscious, as is natural when a number is mentioned of things of one kind.

Philosophical aspectMuṇḍaka’s two birds on one tree — one eats the fruit, the other only watches — are the same pair. For Advaita the difference is due to the adjunct (the mind); the witnessing Self and the experiencing self are, in truth, one.

Other schoolsFor Rāmānuja and Madhva this sūtra shows the eternal distinction of the soul and the Lord, both dwelling in the heart.

The inner controller

MeaningThe inner controller in the gods and the rest (is Brahman), because its qualities are stated.

ExplanationIn Bṛhadāraṇyaka 3.7 Uddālaka asks Yājñavalkya about the thread and the inner controller. Yājñavalkya describes one who dwells in earth, water, fire, the mind and the self, “whom they do not know, whose body they are, who controls them from within — he is your Self, the inner controller, the immortal.” Such universal, unseen control belongs only to Brahman, not to Sāṅkhya’s pradhāna nor to the individual soul (1.2.19–20).

Philosophical aspectGod is not a distant ruler but the innermost Self of every being — “the unseen seer, the unheard hearer”. Advaita takes this to the end: the controller within is one’s own true Self.

Other schoolsThis is the key text for Rāmānuja’s doctrine that the world and souls are Brahman’s body (śarīra) and Brahman their soul.

The invisible source of all beings

MeaningThe one possessed of invisibility and other qualities (is Brahman), because (its) qualities are mentioned.

ExplanationMuṇḍaka 1.1.6 speaks of the imperishable that is invisible, ungraspable, without family or caste, eternal and all-pervading — the source of all beings, which the wise behold everywhere. Is this pradhāna? No: it is called all-knowing, and knowing it is said to make all known.

Philosophical aspectThe highest is described by negation (“not seen, not grasped”), yet it is the source of everything. This double description — beyond all, yet the cause of all — is what Advaita reconciles through the idea of appearance.

The universal person, Vaiśvānara

MeaningVaiśvānara (is Brahman), because of the distinguishing marks, though the word is common.

ExplanationIn Chāndogya 5.11–18 five householders and Uddālaka go to King Aśvapati to learn about Vaiśvānara, “the universal person”. The word can mean digestive fire, elemental fire or a deity. But the passage pictures heaven as his head, the sun as his eye and the earth as his feet, and says that one who knows him eats food in all worlds — marks that fit only Brahman.

Philosophical aspectThe “cosmic person” meditation (virāṭ) shows Brahman as the whole universe with the person as its microcosm — a stepping-stone to the formless.

The support of heaven and earth

MeaningThe abode of heaven, earth and the rest (is Brahman), because of the word “Self”.

ExplanationMuṇḍaka 2.2.5: “That in which heaven, earth and the space between are woven, with the mind and all the senses — know that alone as the Self; leave all other talk; it is the bridge to immortality.” The word “Self” (ātman) and the call to know it alone mark it as Brahman.

Philosophical aspectBrahman is the warp on which all worlds are woven. The image of a bridge (setu) is not a path to somewhere else but a means of crossing over ignorance.

The infinite, bhūmā

MeaningThe infinite (is Brahman), because it is taught after (prāṇa, the one awake in) serenity.

ExplanationIn Chāndogya 7 Nārada climbs with Sanatkumāra from name to speech, mind, will and on to prāṇa, and is finally taught the infinite: “Where one sees nothing else, hears nothing else, knows nothing else — that is the infinite. There is no happiness in the small; the infinite alone is happiness.” Since it is taught beyond prāṇa, it is Brahman.

Philosophical aspectThis is one of the most beautiful definitions of the highest: fullness without a second. Happiness is sought in finite things only because the infinite is our nature; the search ends when the infinite is known.

The imperishable that holds space

MeaningThe imperishable (is Brahman), because it supports (all) up to space.

ExplanationGārgī asks Yājñavalkya what space itself is woven on (Bṛhadāraṇyaka 3.8). He answers: on the imperishable, neither gross nor subtle, without eyes or mind, by whose command sun and moon stand apart. The syllable Om is also called akṣara, but only Brahman supports space.

Philosophical aspectIn the language of negation (neti neti) the highest is described as beyond all properties; yet it is the ground on which everything — even space — rests.

The small space in the heart

MeaningThe small (space in the heart is Brahman), because of the subsequent statements.

ExplanationChāndogya 8.1 speaks of “this city of Brahman” (the body) with a small lotus-house in which there is a small space: “what is in it should be sought.” The passage goes on to say that this inner space holds heaven and earth, does not age with the body and is the Self free from sin, old age, death, grief, hunger and thirst — so it is Brahman.

Philosophical aspectBrahman is to be found in the heart, not as a small thing but as the infinite that seems small only because the heart is its place of discovery. This is the basis of the dahara-vidyā meditation.

Everything shines after it

Meaning(The light is Brahman) because of the shining after (it), and (because it is called the light) of that.

ExplanationKaṭha 2.2.15 (also Muṇḍaka 2.2.10): “There the sun does not shine, nor moon and stars, nor lightning — how then this fire? It shining, everything shines after it; by its light all this is lit.” Only consciousness, not any physical light, is the light by which all lights are known.

Philosophical aspectConsciousness is self-luminous (svaprakāśa): it shows everything and needs nothing to show it. The verse is daily chanted as the meaning of the Self.

The person of the size of a thumb

MeaningThe one of a measured size (the thumb-sized person) is (Brahman), from the very words (used).

ExplanationKaṭha 2.1.12: “The person of the size of a thumb dwells in the body; he is lord of past and future.” The size suggests the individual soul, but “lord of past and future” can only mean Brahman. The next sūtra explains that the size is spoken of with regard to the human heart, where Brahman is to be realised.

Philosophical aspectMeasures given to the immeasurable are teaching devices: the infinite is spoken of in the dimensions of the place where we look for it.

The gods too may seek Brahman

MeaningBādarāyaṇa holds that (beings) above them (the gods) also (are qualified for knowledge of Brahman), because it is possible.

ExplanationGods too have desires, bodies and the capacity to be dispassionate, as the Upaniṣads show (Indra living with Prajāpati to learn the Self). So the gods also are qualified for knowledge of Brahman. In the discussion the existence and embodiment of deities is defended against the Mīmāṃsā view that gods are merely names in mantras.

Philosophical aspectEligibility (adhikāra) depends on desire for freedom and capacity, not on the kind of body. Liberation is open to all conscious beings who can enquire.

Jānaśruti’s grief — the “śūdra” passage

MeaningHis grief (is meant by the word “śūdra”), because he heard their disrespect and ran to (Raikva) — so it is indicated.

ExplanationIn Chāndogya 4.2 Raikva addresses King Jānaśruti as “śūdra”. Was the king a śūdra receiving Vedic knowledge? The sūtra explains the word as “one overcome by grief (śuc)”: he was grieved by the swans’ remark and rushed to the teacher. The adhikaraṇa (1.3.34–38) then rules that Vedic study as such was restricted, while noting that knowledge reached Vidura, Dharmavyādha and others through the epics and Purāṇas.

Philosophical aspectThis is the text’s most socially conditioned passage. Śaṅkara keeps the traditional restriction on formal Vedic study, yet affirms that liberation through knowledge from other sources is open to all; later teachers such as Vivekananda emphasised the second point.

In deep sleep and at death the Lord is distinct

Meaning(The self made of knowledge is the supreme Lord) because it is spoken of as different (from the soul) in deep sleep and at death.

ExplanationBṛhadāraṇyaka 4.3–4 says that in deep sleep the soul is embraced by the supreme Self and knows nothing within or without, and at death it is mounted by the supreme Self. The one embracing is the Lord, distinct from the embraced; so the passage is about Brahman. The difference is spoken of because of adjuncts.

Philosophical aspectDeep sleep is a daily pointer to the Self: no world, no individual, yet one is — and wakes saying “I slept happily.” Advaita builds its analysis of the three states (avasthā-traya) on such texts.

“The unmanifest” of the Kaṭha is not pradhāna

MeaningIf it be said that in some (texts) the inferred (pradhāna) also is mentioned — no, for it is taken as the body in the simile (of the chariot); and (scripture) shows (this).

ExplanationKaṭha 1.3.10–11 says: beyond the great (mahat) is the unmanifest (avyakta), beyond that the Person. Sāṅkhya saw its own series — mahat, avyakta, puruṣa — here. But the Kaṭha has just given the image of the chariot: the self as rider, the body as chariot, the senses as horses. The terms of the later verse take up that image, and “unmanifest” refers to the body in its subtle causal state, not to an independent pradhāna.

Philosophical aspectThe fourth pāda gathers the passages that Sāṅkhya claimed. Their method was to match terms; Bādarāyaṇa’s is to read words within their context.

The creation accounts agree about the cause

Meaning(There is no contradiction) as to (Brahman as) the cause of space and the rest, because it is stated (everywhere) as described (in one place).

ExplanationThe Upaniṣads give different sequences of creation — from space, from fire, from prāṇa; even from “non-being”. Does this make them unreliable about the cause? No: they differ in the order of the created things, but all agree that the cause is the one conscious Brahman. “Non-being” means the unmanifest state of name and form, not nothing.

Philosophical aspectVedānta does not present a cosmology to be believed for its own sake. The purpose of creation texts is to show that everything is Brahman; details vary because they serve that teaching.

Brahman is the material cause too

Meaning(Brahman is) the material cause also, so as not to contradict the proposition and the illustration.

ExplanationChāndogya 6.1 promises: “by knowing that, the unheard becomes heard” — and illustrates: “as by knowing one lump of clay all that is made of clay is known”. This works only if Brahman is the material of the world, as clay is of pots; an efficient cause, like a potter, cannot make his pots known. Brahman is both — it willed and it became.

Philosophical aspectThis sets Vedānta apart from Nyāya and from ordinary theism, where God shapes a separate matter. Since the world is not other than its material cause, it has no reality apart from Brahman — the basis for 2.1.14’s analysis of effect and cause.

Other schoolsAll the major schools accept Brahman as both causes. Rāmānuja understands the change as real (Brahman with its subtle body of souls and matter becomes the gross world); Madhva, alone, denies that Viṣṇu is the material cause and reads prakṛti differently.

It made itself into the world

MeaningBecause (Brahman) made itself (into the world), by transformation.

ExplanationTaittirīya 2.7 says: “That made itself by itself.” The self is both the agent and the object of making; Brahman did not use any other material. The word “transformation” states how the effect comes from the cause in the language of causes and effects.

Philosophical aspectŚaṅkara accepts pariṇāma language for the empirical level, but holds that Brahman is untouched by the change — as a magician is not changed by the illusion. Later Advaitins call this vivarta, apparent change, to distinguish it from real transformation.

Other schoolsFor Rāmānuja and Bhāskara this sūtra proves real transformation: Brahman really becomes the world without losing its perfection.

All the other theories are answered

MeaningBy this all (the other theories) are explained — explained.

ExplanationHaving shown that no Upaniṣad supports pradhāna as the cause, the sūtra says that the same reasoning disposes of other theories, such as atoms, that might claim scriptural support. The repeated word marks the end of the chapter.

Philosophical aspectSāṅkhya is the chief opponent because it was closest to Vedānta and had a genuine scriptural foothold. The first chapter ends with the purport of the Upaniṣads fixed: Brahman, the one conscious cause.
