Brihadaranyaka Upanishad

The Brihadaranyaka Upanishad, belonging to the Shukla Yajurveda, is the largest of all the Upanishads, and it too opens with a grand allegory — the horse of the Ashvamedha sacrifice is seen as a symbol of the entire universe. The horse's head is the dawn, its eye the sun, its breath the wind, its open mouth the fire Vaishvanara, its body the year, its back the heavens, its belly the sky, its hooves the earth, its flanks the directions, its ribs the intermediate directions, its limbs the seasons, its joints the months and fortnights, its feet the days and nights, and its bones the stars.

What follows is an account of creation — "naiveha kinchanagra asit, mrityunaivedam avritam asid ashanaya" — in the beginning, there was nothing here at all; this was covered entirely by Death, or by hunger, for hunger itself is death. That Death created the mind, thinking, "let me have a self (mind)"; and moving about in worship, water was born from it. This chapter also contains that same story of the gods and demons found in the Chandogya Upanishad — the gods, though fewer in number, sought to defeat the demons through the chanting of the Udgitha, and it was, in the end, the chief Prana (Ayasya Angirasa) that won them their victory.

The most profound portion of this chapter is that description in which the Self's solitary existence, at the very dawn of creation, is described — "atmaivedam eka evagra asit purushavidhah" — in the beginning, this was the Self alone, in the shape of a Person. Looking about, it saw nothing other than itself; and it spoke first, "aham asmi" — I am — and from this very utterance arose the name "Aham," I; this is why, even today, when someone is addressed, they answer first, "it is I," and only then give whatever other name they may have. Being alone, it felt fear, but then thought, "since there is nothing other than myself, of what should I be afraid?" — and its fear passed away at once, for fear always arises from some "other."

Finding no joy in its solitude, that Self desired a second, becoming as large as a man and wife together; it then divided itself in two, and from this arose husband and wife (pati and patni). From their union arose human beings; and in this very same way, taking various forms — cow and bull, mare and stallion, and so on, down even to the ants — every pair of creatures came into being. Then that Self recognized, "I myself am this entire creation, for I alone have brought forth all of it" — and through this very realization, it became creation itself. And it is here that the immortal Mahavakya appears — "tad idam apy etarhi ya evam veda aham brahmasmiti sa idam sarvam bhavati" — whoever knows, even today, "I am Brahman," becomes this entire universe; not even the gods can prevent such a person from becoming so, for that person becomes their very own Self.

This Mahavakya, "Aham Brahmasmi," is the most direct and the boldest of the four great Vedantic declarations — it demands no outward worship or surrender at all, but directly equates the seeker's own identity with Brahman itself. This verse reveals that the whole story of creation — freedom from fear, the birth of a pair from solitude, and, at last, the birth of diversity — is, in truth, nothing but that one same Self's own journey of self-discovery, each stage of which brings it ever closer to awareness of its own vast, true nature.

In the second chapter, a highly learned yet proud Brahmin named Gargya Balaki approaches King Ajatashatru of Kashi and declares, "I shall teach you of Brahman." He offers, in turn, the sun, the moon, lightning, space, air, fire, water, the reflection in a mirror, the shadow of the body, and the person in the eye, as Brahman. But the king, a Kshatriya of surprisingly deep knowledge himself, rejects each proposal in turn, showing that these are all merely partial, limited expressions of Brahman, never Brahman itself. In the end, Gargya has nothing further to offer, and falls silent.

The roles then reverse — the king, undertaking this unusual task of instructing a Brahmin, leads Gargya to a sleeping man and shows him that in sleep, when all the senses gather into that person seated within the heart, and, upon being called by name, the sleeper wakes — this proves that it is this very inner, knowledge-formed person seated in the heart who is the true ruler and lord of all, not any of the outward symbols Gargya had proposed. As also happened during the teaching of the doctrine of the five fires in the Chandogya Upanishad, this scene overturns the tradition's ordinary hierarchy of caste roles, showing that true knowledge is never the exclusive property of any one class alone.

This same chapter offers a detailed account of the "Madhu Vidya" — the honey doctrine — the earth is honey for all beings, and all beings are honey for the earth; the shining, immortal Person present within the earth and the person present within the physical body are one and the same. This same honey doctrine extends through water, fire, wind, the sun, the directions, the moon, lightning, thunder, space, righteousness, truth, humankind, and the Self as well — each is declared to be mutual honey (mutual sweetness and support) for the other, and the Self is proclaimed as the honey of all beings, with all beings, in turn, as honey to the Self.

This entire doctrine was first taught to the sage Dadhyach Atharvana by the twin Ashvins, under a threat that if he taught it to anyone else, his head would be severed — since it was, originally, knowledge forbidden to any but the gods themselves. When Indra learned of this, he did indeed cut off Dadhyach's head; but the Ashvins, having foreseen this, had already replaced it with the head of a horse, through which Dadhyach was able to teach this knowledge safely, without breaking the curse — and afterward, the Ashvins restored his own head once more. This colorful backstory of secret transmission reveals just how deeply the ancient tradition guarded and protected profound knowledge from misuse.

The third chapter presents one of the most dramatic scenes in all of Upanishadic literature — King Janaka holds a grand sacrifice and invites all the learned Brahmins of the Kuru-Panchala lands. A prize of a thousand cows, their horns capped with gold, is announced for the most learned Brahmin present. Yajnavalkya, full of confidence, immediately tells his student to drive the cows home. This boldness offends the other scholars present, who begin, one after another, to challenge him with difficult questions.

Ashvala, Artabhaga, Bhujyu, Ushasta, and Kahoda each bring forward their own questions — on the pervasiveness of death, on the movement of the senses after sacrifice, and on that immediate, direct Brahman present within all things — and Yajnavalkya answers each of them with precise, profound clarity. On Artabhaga's question concerning karma, Yajnavalkya even takes him aside from the public assembly to answer privately — "a person becomes virtuous through virtuous action, and sinful through sinful action" — showing that this deep mystery of the law of karma was not considered fit for open discussion.

Then comes Gargi Vachaknavi, the assembly's only woman scholar, who asks two questions. Her first question — upon what is this entire universe woven, warp and weft? — Yajnavalkya answers: upon space. Satisfied, Gargi asks an even bolder question — upon what, then, is space itself woven? Yajnavalkya warns her — "Gargi, do not press too far, or your head may fall" — a formulaic warning marking, in that era's tradition of philosophical debate, a certain permitted boundary of metaphysical inquiry.

Gargi rephrases her question in a different form — upon what is that which lies above heaven and below the earth, and between heaven and earth, and the past, present, and future too, all woven? On this question, Yajnavalkya offers an extensive description of the "Akshara," the Imperishable — it is not coarse, not fine, not short, not long, imperceptible, without eyes, ears, speech, or mind, without inside or outside; nothing tastes it, yet by it, taste itself is tasted; it is the unseen seer, the unheard hearer. By the very command of this Akshara, the sun and moon remain apart in their courses, heaven and earth remain apart, the seasons, months, and years remain in order, rivers flow from the snowy mountains, some eastward and some westward. Gargi, hearing this answer, announces to the whole assembly that no one can defeat Yajnavalkya in a debate on Brahman.

Eventually Vidagdha Shakalya questions Yajnavalkya on the number of the gods — Yajnavalkya answers with a numerical reduction, from three thousand three hundred and six, down through thirty-three, six, three, two, one and a half, and finally to one — revealing that the deities are, in the end, all expressions of that one same reality. Shakalya presses further, with questions on the person dwelling in various parts of the body, until he finally poses a question Yajnavalkya declares unanswerable in that form — and, according to the myth, Shakalya's head falls off, his bones later carried away by robbers, a dark, legendary consequence of losing this philosophical contest. Yajnavalkya, unrivaled, drives the thousand cows home.

In the fourth chapter, Yajnavalkya offers Janaka his deepest teachings, but its most touching portion is his conversation with his own wife, Maitreyi. When Yajnavalkya resolves to renounce the world and divide his property between his two wives, Maitreyi and Katyayani, Maitreyi asks, "if the whole earth, filled with wealth, were mine, would I become immortal through it?" Yajnavalkya answers plainly — no, wealth brings only a life like that of the rich, never immortality. Maitreyi answers at once, "what should I do with something that will not make me immortal? Teach me, instead, what you yourself know."

Delighted by Maitreyi's question, Yajnavalkya teaches her — "a husband is not dear that you may love the husband, but that you may love the Self; that is why the husband is dear" — and in exactly the same way, wife, sons, wealth, cattle, priesthood, kingship, the worlds, the gods, all beings, everything, is dear not for its own sake, but for the sake of the Self. Therefore, the Self alone should be seen, heard of, reflected upon, and meditated upon — for by the knowledge of the Self, all this becomes known.

Toward the close of this conversation, Yajnavalkya raises an extraordinary philosophical question — where there is duality, one may smell another, see another, hear another; but when the Self alone has become this entire universe, then whom shall one smell, whom shall one see, whom shall one hear? And the deepest question of all — "vijnataram are kena vijaniyat" — O Maitreyi, by what means could one possibly know the Knower itself? This question touches the very limit of epistemology — just as an eye cannot see itself, the knower cannot make itself an object of its own knowing.

In this same chapter, Yajnavalkya also gives Janaka a detailed account of the states of waking, dreaming, and deep sleep, and offers an exquisite image for the soul's journey after death — "just as a caterpillar, having reached the end of a blade of grass, draws itself together to make its way onto the next blade, so too the soul, casting off this body, dispelling ignorance, draws itself together to take on a new and more beautiful form." This image portrays death not as any kind of ending, but as the next step of a continuous journey — this Self is Brahman, made of understanding, mind, breath, sight, hearing, and everything else besides.

The chapter closes with a profound teaching on karma — "yat karta tat bhavati" — as one acts, so one becomes; the doer of good becomes good, the doer of evil becomes evil; one becomes pure through pure deeds, impure through impure deeds. But there is a still deeper principle here — a person is made of desire; as is a person's desire, so is their resolve; as is their resolve, so is their deed; and whatever deed they perform, that they attain. This principle traces the root cause of karma not to action itself, but to desire and resolve, showing that inward desire is the true parent of both outward action and destiny.

The fifth chapter, opening the "Khila Kanda" (the supplementary portion), presents an exceptionally beautiful and memorable parable. Prajapati had three kinds of offspring — gods, human beings, and demons — all of whom, having completed their studies as celibate students under their father, asked him for some final instruction. To the gods, Prajapati uttered a single syllable — "Da" — and asked, "have you understood?" The gods answered, "we have understood: you said 'damyata' — restrain yourselves" — since the gods are, by their very nature, prone to unruly indulgence in pleasure and the senses. Prajapati confirmed, "yes, you have understood."

The human beings then asked the very same question, and Prajapati again uttered the same syllable, "Da," and they answered, "we have understood: you said 'datta' — give, be charitable" — since human beings, by their very nature, tend toward greed and accumulation. Prajapati agreed. Finally the demons asked the same question, and hearing that same syllable, "Da," they answered, "we have understood: you said 'dayadhvam' — be compassionate" — since demons, by their very nature, tend toward cruelty. Prajapati confirmed their answer as well. And the voice of the thunder in the sky repeats this very same "Da, Da, Da" even now — "damyata, datta, dayadhvam" — restrain yourselves, give, be compassionate — three virtues drawn, with remarkable ingenuity, from a single, repeated syllable.

The fact that one and the same syllable gave rise to three distinct, yet equally valid, teachings carries a profound significance — it shows that the expression of ultimate truth naturally adapts itself to the particular nature and need of each listener. One and the same teacher's word can carry different, yet equally fitting, meaning for different students. This is exactly why, even today, the sound of thunder in the clouds — "Da Da Da" — is understood as a continual reminder of these three very virtues: restraint, generosity, and compassion, as though nature itself were repeating this threefold teaching without pause.

This chapter also explains that Prajapati himself is called "hridayam" (the heart), because the word "hridayam" may be understood as "hrid" (this) and "ayam" (is) — "this it is" — that reality which is directly, immediately experienced. This chapter shows that the deepest teachings of the Upanishads can be heard not only in intricate philosophical argument, but even in the simplest events of nature, such as the rumble of thunder in the clouds — provided the seeker's heart is ready to listen.

The sixth and final chapter turns from philosophical heights to the practical duties of householder life. It restates, in brief, the doctrine of the five fires, reaffirming how the cycle of birth and rebirth unfolds as a continuous sacrifice of faith, Soma, rain, food, and seed. It also describes various domestic rituals in detail, among which one deserves particular mention — the "putreshti," a rite performed by a couple wishing for a wise and learned son, involving specially prepared rice and particular mantras.

This chapter shows that however lofty the philosophical heights the Upanishad may reach, it never neglects daily life, family, and society. This is proof that, in the vision of the ancient Indian sages, Self-knowledge and the duties of household life were never at odds with one another — the very same person could remain absorbed in the deepest contemplation of ultimate reality, while also fully carrying out their duties toward family, children, and society.

The Upanishad closes with a particularly significant portion — the "Vamsa Brahmana," the lineage of teachers — a long chain of names, passed down from teacher to student, generation after generation, tracing all the way back to the self-existent Brahma himself. This lineage is far more than a dry list — it is living proof that this profound knowledge was never the original discovery of any single individual, but a precious treasure, carefully preserved across countless generations through the teacher-student tradition, with the utmost care and reverence.

Through this lineage, the Upanishad conveys a further message — the true continuity of knowledge lies not in any one person's individual brilliance, but in the alertness of an unbroken tradition — every teacher entrusted this knowledge to their student in the firm faith that it would be carried forward and preserved, and this chain has remained unbroken for thousands of years. The Upanishad's very last words are "namo brahmane, namo brahmane" — salutation to Brahman, salutation to Brahman — a double salutation that gathers up, in its humility, the whole spirit of this vast, profound text — a journey that has carried us from the origin of creation, through Gargi's fearless questions and Maitreyi's heart-touching conversation, all the way to the practical duties of the home.
