Śruti — that which was heard

Śruti is not what someone wrote. It is what the ṛṣis heard — the word 'ṛṣi' means seer, one who saw the mantra rather than composed it. The claim is precise: the Veda is apauruṣeya, not of personal authorship, and therefore carries no author's fallibility.

What apauruṣeya claims and does not claim

• It does not claim a god dictated it — Mīmāṁsā, which defends the doctrine most rigorously, does not require a creator at all.
• It claims the mantras are eternally existent sound-structures, and the ṛṣis are the ones who perceived them.
• It follows that the Veda has no date of composition, only dates of perception and of transmission.
• It follows that error cannot enter through an author's ignorance, since no author intervened.
• It follows that śruti is self-valid: it does not depend on any other text to establish it.

The Upaniṣads describe the Veda's origin in a single image, and the image is chosen with care: not speech, not composition, not dictation, but breathing out. Yājñavalkya uses it while teaching Maitreyī.

Breathing out is not an act of will. One does not decide the content of one's own exhalation, and one does not author it. That is exactly the force of the metaphor: the Veda proceeds from Being as breath proceeds from a body — necessarily, without deliberation, and without a composer standing outside it choosing what to say. The Ṛgveda's own hymn of the cosmic person puts the same claim in the language of sacrifice: the metres and the Vedas are not made by anyone, they are born.

Jajñire — 'were born'. Not racita, composed; not likhita, written. The verb the hymn selects belongs to the vocabulary of generation, not of authorship, and Mīmāṁsā builds its entire defence of apauruṣeya on the fact that the tradition nowhere preserves a memory of anyone composing a single mantra — only of ṛṣis to whom mantras were disclosed.

Mīmāṁsā's argument: the word and its meaning were never joined

The strongest philosophical defence of śruti comes from Pūrva Mīmāṁsā, and it does not appeal to God at all. Jaimini's argument is about language. If the connection between a word and its meaning had been made at some moment by someone, then language would be a convention, and a convention can be mistaken. Jaimini denies the premise.

If the word-meaning bond is autpattika — there from the origin, not instituted — then Vedic sentences are not somebody's assertions that might be false; they are the standing relation of sound to sense, and their authority needs no external certifier. This is why the same text can define dharma without reference to any deity at all, purely as what Vedic injunction indicates.

The preservation — the most exact oral transmission ever devised

The Veda was carried for thousands of years without writing, and with a fidelity that written traditions do not achieve. It was done by mathematics. The text was memorised not once but in a series of permutations, so that any error in one recitation was exposed by the others.

The engineering behind that result is worth naming plainly, because it is a genuine and unexaggerated point of contact with modern information science. The pāṭhas are redundancy encoding. Ghana-pāṭha stores every word of the text roughly thirteen times, embedded in overlapping forward and reverse sequences, so that a single corrupted syllable no longer fits its neighbours in several independent recitations at once — the error is not merely detectable but localisable, exactly as a checksum localises a corrupted byte. Nothing in the design is accidental: the tradition wanted a transmission channel with no loss, over centuries, across a subcontinent, using only human memory, and it built one.

What counts as śruti

All four layers of all four Vedas — Saṁhitā, Brāhmaṇa, Āraṇyaka and Upaniṣad. The Upaniṣads are śruti; the Gītā, though it carries comparable standing in practice, is technically smṛti. Some Āgama traditions claim śruti status for their own revelation; the Vedic schools do not concede it, and both positions are on the record.
