Hindu scripture is not one shelf. It is two classes with different kinds of authority, and the distinction is not about which is older or which is more loved. It is about what to do when they disagree — and the tradition has an explicit rule for that, stated in the texts themselves.
📚 Shruti and Smriti at a Glance
Shruti: “what was heard” — the Vedas, in four parts each
Smriti: “what was remembered” — everything else authoritative
The difference: authority, not age or importance
Shruti is: apaurusheya — without human author, on the classical view
Smriti is: authored, by named rishis, and revisable
The rule: where they conflict, shruti prevails
📑 Table of Contents
👂 What Is Shruti
Shruti is the Veda, and the Veda is four collections each having four layers:
| Layer | Contains |
|---|---|
| Samhita | The mantras themselves — the hymns |
| Brahmana | Prose on the performance and meaning of the rites |
| Aranyaka | The "forest" texts — ritual internalised, transitional |
| Upanishad | The philosophical portion; the jnana-kanda |
📌 The Upanishads are shruti
This is the point most often missed. The Upanishads are not a separate category of text appended to the Veda — they are the fourth layer of the Veda itself, which is why they carry the highest authority and why Vedanta calls them the shruti prasthana. The Bhagavad Gita, by contrast, is smriti, however much it is loved.
🧠 What Is Smriti
Everything else with religious authority. The class is enormous:
| Category | Includes |
|---|---|
| Itihasa | The Ramayana and the Mahabharata — and so the Bhagavad Gita |
| Purana | The 18 Mahapuranas and the Upapuranas |
| Dharmashastra | Manusmriti, Yajnavalkya Smriti, Narada, Parashara and others |
| Vedanga | The six auxiliary disciplines |
| Agama / Tantra | Shaiva, Vaishnava and Shakta ritual and theological texts |
| Sutra literature | Kalpa, Grihya, Shrauta and Dharma Sutras |
| Darshana texts | The founding sutras of the six systems |
💡 Smriti is deliberately revisable
Because smriti is authored, it is understood to be composed for a time, a place and a condition. The Dharmashastra texts say so themselves: they distinguish yuga-dharma — what applies in a given age — and record that practices proper in one age are prohibited in another. Parashara's smriti is explicitly framed as the one for the Kali age. The category has change built into it, and this is the tradition's own mechanism, not a modern accommodation.
⚖️ The Rule of Conflict
The tradition states the hierarchy explicitly rather than leaving it to be inferred:
Where there is a conflict between shruti and smriti, shruti prevails. Where two smritis conflict, reasoning and established practice decide, and the option is left open.
| Order | Authority | Note |
|---|---|---|
| 1 | Shruti | Decisive where it speaks directly |
| 2 | Smriti | Authoritative where shruti is silent — and presumed to rest on a lost Vedic text |
| 3 | Sadachara | The practice of the virtuous and learned |
| 4 | Atma-tushti | What satisfies one's own conscience — named last, and named |
📌 The presumption behind smriti
Mimamsa's account of why smriti binds at all is subtle: a smriti rule is presumed to be based on a Vedic text now lost. That presumption is defeated if the smriti rule contradicts an available shruti text, or if a worldly motive for the rule can be shown. In other words, the tradition supplied a formal method for setting aside a smriti rule — and it is a method internal to the tradition's own logic.
🗃️ Reading the Distinction Honestly
What the distinction does and does not settle.
- It does establish that no smriti text, however revered, overrides shruti. Manusmriti is smriti. The Puranas are smriti. The Gita is smriti.
- It does mean that smriti is time-bound by the tradition's own account, and that the tradition provided for its revision.
- It does not mean smriti is unimportant. Almost all of lived Hindu practice — festivals, samskaras, temple worship, most theology, most narrative — is smriti and agama. Shruti governs; smriti is where people live.
- It does not resolve every dispute, because shruti is often silent on what is being argued about, in which case the lower authorities operate and sampradaya — the tradition one belongs to — decides.
A quick test for any text
- Is it in one of the four Vedas, in any of its four layers? Then shruti.
- Does it have a named human author or compiler? Then smriti.
- Does it call itself a smriti, purana, tantra, agama, shastra or sutra? Then smriti.
- Is it a stotra, a bhajan, a modern commentary? Then it is devotional or interpretive literature, valuable and outside both formal classes.
❓ Frequently Asked Questions
What is the difference between shruti and smriti?
Shruti (“what was heard”) is the Vedas in all four layers — Samhita, Brahmana, Aranyaka and Upanishad. Smriti (“what was remembered”) is everything else authoritative: the epics and so the Gita, the Puranas, Dharmashastras, Vedangas, Agamas, sutras, darshana texts. The difference is authority, not age or importance — shruti is authorless, smriti is authored and revisable.
Are the Upanishads shruti or smriti?
Shruti — and this is the point most often missed. The Upanishads are not appended to the Veda; they are the fourth layer of the Veda itself, which is why they carry the highest authority and are called the shruti prasthana. The Bhagavad Gita, by contrast, is smriti, however much it is loved.
What happens when shruti and smriti conflict?
Shruti prevails, and the tradition states this explicitly. The full order is shruti → smriti → sadachara (the practice of the virtuous and learned) → atma-tushti (what satisfies one's own conscience — named last, and named). Where two smritis conflict, reasoning and established practice decide, and the option is left open.
Can smriti change?
Yes, and the tradition built that in. Smriti is composed for a time, place and condition — the Dharmashastras say so, distinguishing yuga-dharma and recording that practices proper in one age are prohibited in another; Parashara's smriti is explicitly framed for the Kali age. Mimamsa adds a formal mechanism: a smriti rule binds because it is presumed to rest on a lost Vedic text, and that presumption is defeated by contradiction with available shruti or by a demonstrable worldly motive.
🙏 Conclusion
Shruti is the Veda in all four of its layers, including the Upanishads; smriti is everything else, from the Gita to the Puranas to the law books. The distinction is about authority, and the tradition states the tie-breaker plainly: shruti wins. What is easy to miss is the second half — smriti is authored, is composed for its age, and is designed to be revisable. That is not a modern reading of the tradition. It is what the smriti texts say about themselves.
