Aiterya Upanishad

The Aitareya Upanishad (ऐतरेय उपनिषद् / Aitareyopaniṣad) is one of the oldest and most profound Upanishads, forming part of the Rig Veda and traditionally associated with the sage Mahidasa Aitareya. Within its short span it carries the entire arc of Vedic philosophy — from the cosmic creation of the worlds and the senses to the crowning declaration that Consciousness itself is Brahman (Prajnanam Brahma, प्रज्ञानं ब्रह्म). The rendering below follows the translation by Swami Gambhirananda, published by Advaita Ashram, Kolkata.

The Shanti Mantra (Peace Invocation)

Every Upanishad opens with a shanti mantra (शान्ति मन्त्र / śānti mantra) to harmonise speech, mind, and body before study:

Om ! May my speech be based on (i.e. accord with) the mind;May my mind be based on speech.O Self-effulgent One, reveal Thyself to me.May you both (speech and mind) be the carriers of the Veda to me.May not all that I have heard depart from me.I shall join together (i.e. obliterate the difference of) dayAnd night through this study.I shall utter what is verbally true;I shall utter what is mentally true.May that (Brahman) protect me;May That protect the speaker (i.e. the teacher), may That protect me;May that protect the speaker – may That protect the speaker.Om ! Peace ! Peace ! Peace !

Chapter I: The Creation of the Worlds

The Absolute Self Alone (I-i)

I-i-1: In the beginning this was but the absolute Self alone. There was nothing else whatsoever that winked. He thought, "Let Me create the worlds."

I-i-2: He created these worlds, viz. ambhas (the waters beyond), marici (rays), mara (the mortal), apah (the waters below). That which is beyond heaven is ambhas; heaven is its support; the sky is marici; the earth is mara; the worlds that are below are the apah.

I-i-3: He thought, "These then are the worlds. Let Me create the protectors of the worlds." Having gathered up a (lump of the) human form from the water itself, He gave shape to it.

I-i-4: As He deliberated upon this human form (Virat), its mouth parted just as an egg does, and the deities of the senses emerged in order:

• From the mouth emerged speech; from speech came Fire.
• From the nostrils came the sense of smell; from smell came Vayu (Air).
• From the eyes came sight; from sight came the Sun.
• From the ears came hearing; from hearing came the Directions.
• From the skin came hair (touch); from touch came Herbs and Trees.
• From the heart issued the mind; from the mind came the Moon.
• From the navel came the organ of ejection; from it issued Death.
• From the procreative organ came the procreative organ; from it came Water.

The Deities Seek Their Abodes (I-ii)

I-ii-1: These deities, that had been created, fell into this vast ocean. He subjected them to hunger and thirst. They said, "Provide an abode for us, staying where we can eat food."

I-ii-2: For them He brought a cow, and then a horse — but they said neither was adequate.

I-ii-3: For them He brought a man. They said, "This one is well formed; man indeed is a creation of God Himself." To them He said, "Enter into your respective abodes."

I-ii-4: Fire entered the mouth as the organ of speech; Air entered the nostrils as the sense of smell; the Sun entered the eyes as sight; the Directions entered the ears as hearing; Herbs and Trees entered the skin as hair (touch); the Moon entered the heart as the mind; Death entered the navel as Apana; Water entered the procreative organ as semen.

I-ii-5: Hunger and Thirst were given their livelihood among these very gods, made sharers of their portions — therefore, whenever an oblation is offered to any deity, Hunger and Thirst verily become sharers with that deity.

The Creation of Food (I-iii)

I-iii-1 to I-iii-10: The Self created food, but the food turned back and attempted to run away. He tried to seize it through speech, smell, the eye, the ear, touch, the mind, and the procreative organ — failing with each, for had He succeeded, one would be satisfied merely by talking of, smelling, seeing, hearing, touching, thinking of, or ejecting food. He finally caught the food through Apana (the downward vital energy), which is therefore known as the devourer of food — the vital energy that depends on food for its subsistence.

I-iii-11: He thought, "How indeed can it be there without Me?" and asked through which of the two ways He should enter.

I-iii-12: Having split open this very end, He entered through this door. This entrance is known as vidriti (the chief entrance); hence it is delightful. Of Him there are three abodes — three (states of) dream.

I-iii-13: Being born, He manifested all the beings. He realised this very Purusha as Brahman, the most pervasive, thus: "I have realised this."

I-iii-14: Therefore His name is Idandra (इदन्द्र / Idandra — "this He has realised"). He is verily known as Idandra; although He is Idandra, they call Him indirectly Indra, for the gods are verily fond of indirect names.

Chapter II: The Three Births of the Self

II-i-1: In man indeed is the soul first conceived. That which is the semen is extracted from all the limbs as their vigour. When he sheds it into his wife, he procreates it. That is its first birth.

II-i-2: The foetus becomes non-different from the wife, just as much as her own limb — therefore it does not hurt her, and she nourishes this self of his that has entered her womb.

II-i-3: She, the nourisher, becomes fit to be nourished. The father protects the son soon after birth, and thereby protects his own self for the continuance of these worlds. That is the second birth.

II-i-4: The son is substituted (by the father) for the performance of virtuous deeds; then the father, having his duties ended and advanced in age, departs and takes birth again. That is the third birth.

II-i-5: This was declared by the seer: "Even while lying in the womb, I came to know of the birth of all the gods. A hundred iron citadels held me down. Then, like a hawk, I forced my way through by dint of knowledge of the Self." Vamadeva (वामदेव / Vāmadeva) said this while still lying in the mother's womb.

II-i-6: He who had known thus became identified with the Supreme and attained all desirable things even here; and having ascended higher after the destruction of the body, he became immortal in the world of the Self — he became immortal.

Chapter III: Consciousness Is Brahman

III-i-1: What is It that we worship as this Self? Which of the two is the Self? Is It that by which one sees, or that by which one hears, or that by which one smells odour, or that by which one utters speech, or that by which one tastes the sweet or the sour?

III-i-2: It is this heart (intellect) and this mind. Sentience, rulership, secular knowledge, presence of mind, retentiveness, sense-perception, fortitude, thinking, genius, mental suffering, memory, ascertainment, resolution, life-activities, hankering, passion — all these verily are the names of Consciousness.

III-i-3: This One is (the inferior) Brahman; this is Indra, this is Prajapati; this is all these gods; and this is the five elements — earth, air, space, water, fire; and all creatures born of eggs, of wombs, of moisture — horses, cattle, men, elephants, and all that move, fly, or do not move. All have Consciousness as the giver of their reality; all are impelled by Consciousness; the universe has Consciousness as its eye and Consciousness is its end. Consciousness is Brahman.

III-i-4: Through this Self that is Consciousness, he ascended higher up from this world, and getting all desires fulfilled in that heavenly world, he became immortal — he became immortal.

The text closes by repeating the shanti mantra and the words: "Here ends the Aitareyopanishad, as contained in the Rig-Veda."

Practical / Modern Context

In a world of constant distraction, the Aitareya Upanishad offers a framework for self-inquiry that remains profoundly relevant. Its message is that Consciousness — Prajnana — is the very foundation of who we are, the silent witness behind seeing, hearing, thinking, and feeling.

• Meditation practice: The verse-by-verse unfolding of the senses (Chapter I) can be used as a guided meditation — tracing sight, hearing, smell, taste, and touch back to the one Consciousness that illumines them.
• Identity and self-worth: Chapter II's teaching on the three births reminds modern readers that we are sustained by family, lineage, and the virtuous deeds we perform — a timeless basis for gratitude toward parents.
• Mindfulness: Chapter III invites us to step back from the stream of thoughts and recognise that all mental states — joy, memory, passion, sorrow — are simply names of one Consciousness, and that realising it is the end of seeking.

Common Misconceptions

1. The correct name is Aitareya, not Aiterya. The Upanishad is properly the Aitareya Upanishad (ऐतरेय), after the sage to whom it is traditionally attributed; "Aiterya" is simply a common misspelling of the same text.
2. It is not a ritual manual. Many assume the Upanishads prescribe external worship. In truth, the Upanishads form the jnana kanda (knowledge portion) of the Vedas, concerned with realising Brahman/Atman, not with performing yajnas or fire rituals.
3. The "three births" are not past lives. Chapter II's three births refer to (1) conception, (2) birth and nurture by the mother, and (3) the father's continuation through the son's virtuous deeds — a teaching about family and lineage, not a doctrine of successive reincarnations.
4. Indra here is not the storm-god of the Vedas. The text explains that the realised Self is called Idandra ("this He has realised"), and only indirectly Indra — the gods are fond of indirect names.

Conclusion

The Aitareya Upanishad is a jewel of the Rig Veda, condensing the entire journey of Vedanta into a handful of chapters: from the absolute Self willing the worlds into being, to the entry of Consciousness into the human form, to the thunderous declaration that Prajnanam Brahma — Consciousness is Brahman. Studying it with devotion and reflection, as the shanti mantra asks, lets speech accord with mind and mind with speech, until the seeker realises the immortal Self that is one with all.
