Brahadaranyaka Upanishad - Part 1

The Brihadaranyaka Upanishad (बृहदारण्यक उपनिषद्) — the "Great Forest Teaching" — is the longest and among the oldest of the Upanishads, forming part of the Shukla Yajurveda. Part 1 unfolds the opening sections of this great text: the meditation on the Horse-sacrifice, the process of creation, the glory of the vital breath (Prana), and the supreme realization of the Self as Brahman.

Invocation

Om. That is full; this is full. This fullness has been projected from that fullness. When this fullness merges in that fullness, all that remains is fullness.

Om. Peace! Peace! Peace!

Part One

Chapter I — Meditation on the Horse-Sacrifice

The meditation identifies the sacrificial horse with the cosmos itself:

• The head of the sacrificial horse is the dawn, its eye the sun, its vital breath the wind, its open mouth the Vaisvanara fire, and its trunk the year.
• Its back is heaven, the belly the intermediate region, the hoof the earth, the sides the four quarters, the ribs the intermediate quarters, the limbs the seasons, the joints the months and half-months, the feet the days and nights, the bones the stars, and the flesh the clouds.
• Its half-digested food is the sand, the blood-vessels the rivers, the liver and lungs the mountains, and the hair the herbs and trees.
• The fore part of the horse is the rising sun, the hinder part the setting sun; its yawn is lightning, its shaking thunder, its water rain, and its neighing indeed voice.

The day is the golden cup called mahiman in front of the horse, its source the eastern sea; the night is the silver cup behind it, its source the western sea. As a racer the horse carried the gods, as a stallion the gandharvas, as a runner the demons, and as a horse, men. The sea is its stable and the sea, its source.

Chapter II — The Process of Creation

• In the beginning nothing whatsoever existed; all this was covered by Death — by hunger, for hunger is verily death. He desired, "Let Me have a mind," and created the mind, then moved about worshipping Himself. From Him worshipping, water was produced; that is why the fire of the Horse-sacrifice is called arka.
• Water is arka. What was then like froth on the water became solidified — that was earth. From the fatigued and heated Hiranyagarbha came forth His essence as brightness — that was Fire. He divided Himself into three: the sun one-third and the air one-third; thus Prana is divided into three.
• He desired, "Let a second self be born of Me," and brought about the union of speech with the mind. The seed became the year; when the child was born Death opened His mouth to devour it, and it cried "Bhan!" — and that became speech.
• Through the union of speech and mind He brought forth all this — the Rig-Veda, Yajur-Veda, Sama-Veda, the metres, the sacrifices, men and animals — and resolved to eat all of it. Because He eats everything, He is called Aditi.
• His body swelled (asvat), and so it came to be called horse (asva); because it became fit for sacrifice (medhya), the rite is called Asvamedha. The sun who shines yonder is the Horse-sacrifice, His body the year; the earthly fire is the arka. These two — fire and the sun — become the same god, Death. He who knows this conquers further death; death cannot overcome him.

Chapter III — The Prana: Its Glories and Redeeming Power

• There were two classes of Prajapati's sons — the gods (devas) and the demons (asuras) — and they struggled for mastery of these worlds. Overwhelmed, the gods resolved to overcome the demons at the sacrifice by means of the Udgitha chant.
• They asked the organ of speech to chant, then smell, then sight, then hearing, then the mind. In each case the demons pierced the organ with evil — and that is the evil found today when one speaks, smells, sees, hears or thinks improperly.
• At last they asked the vital breath in the mouth (prana) to chant. When the demons charged to pierce it with evil, they were scattered like a clod of earth striking a stone — crushed and completely destroyed. The gods became established in their true selves and the demons perished.
• Prana is called ayasya angirasa (the essence of the limbs), Brihaspati (lord of the Rig-Veda), Brahmanaspati (lord of the Yajur-Veda), Saman and Udgitha. The vital breath is ut (that by which all this universe is upheld) and speech is githa (song).
• This chapter carries the celebrated prayer of the sacrifice: "Lead me from the unreal to the real. From darkness lead me to light. From death lead me to immortality." Here "the unreal" and "darkness" mean death, and "the real" and "light" mean immortality.

Chapter IV — The Creation and Its Cause

• In the beginning this universe was the Self (Viraj) alone, in the shape of a person. He reflected and saw nothing else but Himself, and first said, "I am He." Because He was before (purva) all aspirants and burnt (aushat) all evils, He is called Purusha.
• He was afraid; but since there was nothing else, there was nothing to fear — fear arises from a second entity. He was not happy alone and desired a mate. He divided this body into two; from that division arose husband (pati) and wife (patni), and from their union human beings were born. Thereafter He produced everything that exists in pairs, down to the ants.
• He produced fire from His mouth and hands, and soma from semen; this universe is indeed food and the eater of food — soma is food, and fire the eater of food.
• The universe was undifferentiated and became differentiated by name and form. This Self has entered into these bodies up to the very tips of the nails, as a razor lies hidden in its case. It is called prana when breathing, speech when speaking, the eye when seeing, the ear when hearing, the mind when thinking — these are merely Its names according to Its functions.
• "This self was indeed Brahman in the beginning. It knew itself only as 'I am Brahman.' Therefore it became all." Whoever among gods, seers or men realizes the self as "I am Brahman" becomes all this universe. Yet if a man worships another deity, thinking "He is one and I am another," he does not know — and therefore it is not pleasing to the gods that men should know this.
• He projected the forms of the brahmin, kshatriya, vaisya and sudra; He projected justice (dharma), and that which is justice is truth. If one departs from this world without realizing his own World (the Self), It does not protect him, and even many meritorious acts will in the end perish for him. One should meditate only upon the World called the Self.
• The complete sacrifice of the self has five factors: the mind is the self, speech the wife, the vital breath the child, the eye human wealth, the ear divine wealth, and the body the instrument of rites.

Chapter V — Manifestations of Prajapati

• The father produced seven kinds of food through meditation and rites: one common to all eaters, two assigned to the gods, three designed for himself, and one given to the animals. On it rests everything that breathes and breathes not. He who knows the cause of the inexhaustibility of food eats food with pre-eminence and lives on nectar.
• The three designed for himself are the mind, the organ of speech and the vital breath — for desire, determination, doubt, faith, steadfastness, shame, intelligence and fear are all truly the mind. These three are the three worlds (earth, sky, heaven), the three Vedas, the gods, Manes and men, and father, mother and child.
• Prajapati, represented by the year, consists of sixteen parts — the nights and days are fifteen of His parts and the constant point is the sixteenth. He permeates all living beings as the new-moon night; on that night let no one cut off the breath of any breathing being, not even of a lizard.
• The world of men is gained through a son, the world of the Manes through rites, and the world of the gods through meditation; the world of the gods is the best of worlds.
• At the hour of death the father says to his son: "You are Brahman, you are the sacrifice and you are the world." The son replies, "I am Brahman, I am the sacrifice, I am the world," and exonerates the father from any duty left undone.
• The gods observed the vow of that from which the sun rises and in which it sets. So a man should observe a single vow — the functions of prana and apana — lest the evil of death overtake him.

Chapter VI — The Three Aspects of the Universe

This universe is a triad of name, form and work:

• Of names, speech is the source (uktha), the common feature (saman) and their Brahman (self).
• Of forms, the eye is the source, the common feature and their Brahman.
• Of work, the body is the source, the common feature and their Brahman.

These three together are one — this body; and the body, although one, is these three. This immortal entity is covered by truth: the vital breath is the immortal entity, and name and form are truth by which the immortal entity is covered.

Practical / Modern Context

The Brihadaranyaka Upanishad is not abstract philosophy but a manual for living consciously. Its central teaching — "I am Brahman" (Aham Brahmasmi) — invites each person to move from a self defined by roles, wealth and possessions toward the Self that underlies them all. Practically, this translates into acting with less attachment to results, seeing the same Self in others, and finding fearlessness that comes from knowing one is never truly alone.

The meditation on the Horse-sacrifice is an early example of cosmic symbology — seeing the universe in a single object — which modern mindfulness and contemplative practice echo. The famous prayer "Asato Ma Sadgamaya" (Lead me from the unreal to the real) remains a daily chant in schools, homes and temples, guiding seekers from darkness to light.

Common Misconceptions

1. "The Upanishads are purely theoretical." The Brihadaranyaka is intensely practical, prescribing meditations (upasanas), contemplations and vows, and teaching that knowledge of the Self transforms how one lives and acts.
2. "'I am Brahman' promotes ego." The teaching destroys the ego: it reveals the limited, individual self to be one with the universal Self, beyond name, form and possession.
3. "The Horse-sacrifice is only a literal ritual." The Upanishad recasts the sacrifice as an inner meditation — the universe as the horse, fire and sun as one deity, and liberation through knowledge rather than ritual slaughter.

Conclusion

Part 1 of the Brihadaranyaka Upanishad carries the seeker from the ritual altar to the innermost Self. Beginning with the cosmic meditation on the Horse-sacrifice, it journeys through creation, the redeeming power of Prana, and culminates in the blazing realization: "I am Brahman." This is the foundation upon which the rest of the great Upanishad — and all of Vedanta — is built.
