Hindu philosophy is not one position. It is a set of six systems that agree on very little except the authority of the Veda, and that spent roughly two thousand years arguing with each other in writing. They are the shad darshanas — the six views — and the word darshana means seeing rather than doctrine, which is itself a claim about what philosophy is for.
👁️ The Six Darshanas at a Glance
Called: shad darshana — the six views
Shared: acceptance of the Veda as a means of knowledge — this is what astika means
Not shared: God, the nature of the self, the number of real categories, how liberation happens
Paired as: Nyaya–Vaisheshika, Samkhya–Yoga, Mimamsa–Vedanta
Opposed by: the nastika schools — Buddhism, Jainism, Charvaka
Written as: sutras — aphorisms, unusable without commentary

📖 What Astika Actually Means
A widespread mistranslation. Astika is routinely rendered “theistic” and nastika “atheistic.” In the classification of the darshanas that is wrong, and the error matters:
- Astika = accepting the Veda as a valid means of knowledge (pramana).
- Nastika = not accepting it.
This is why Samkhya and Purva Mimamsa, both of which are classified as astika, do not require a creator God — Samkhya's classical form is explicitly nirishvara, without a Lord, and Mimamsa holds the Veda to be authorless and eternal so that no God is needed to issue it. Both are orthodox. Neither is theistic in the ordinary sense.
| # | Darshana | Founding sutra | Traditionally by | Its central concern |
|---|---|---|---|---|
| 1 | Nyaya | Nyaya Sutras | Gautama (Akshapada) | Logic, valid knowledge, debate |
| 2 | Vaisheshika | Vaisheshika Sutras | Kanada | Categories of what exists; atomism |
| 3 | Samkhya | Samkhya Karika | Kapila (Karika by Ishvarakrishna) | The 25 tattvas; purusha and prakriti |
| 4 | Yoga | Yoga Sutras | Patanjali | Stilling the mind; the eight limbs |
| 5 | Purva Mimamsa | Mimamsa Sutras | Jaimini | Dharma; the authority of the Vedic injunction |
| 6 | Uttara Mimamsa / Vedanta | Brahma Sutras | Badarayana | Brahman; the meaning of the Upanishads |
🔗 Why They Come in Pairs
The traditional ordering pairs them, and the pairings are not arbitrary — in each case one system supplies the metaphysics and the other the method or the application.
| Pair | The relation |
|---|---|
| Nyaya + Vaisheshika | Vaisheshika says what kinds of things exist; Nyaya says how we know anything and how to argue about it. They merged in later centuries into the Nyaya-Vaisheshika synthesis. |
| Samkhya + Yoga | Samkhya supplies the analysis — purusha, prakriti, the twenty-five tattvas — and Yoga supplies the practice that acts on it. Patanjali takes Samkhya's metaphysics almost entire and adds Ishvara. |
| Purva + Uttara Mimamsa | Two halves of the enquiry into the Veda. Purva Mimamsa takes the karma-kanda, the ritual portion, and asks what dharma is. Uttara Mimamsa — Vedanta — takes the jnana-kanda, the Upanishads, and asks what Brahman is. |
📌 The disagreements are real
These are not six flavours of one position. Nyaya holds the self to be a substance with qualities; Advaita holds it to be identical with Brahman; Samkhya holds there to be innumerable selves, each entirely inactive. Vaisheshika builds the world from atoms; Advaita denies the world's ultimate reality. Mimamsa says liberation is not even the goal — the goal is dharma. Any account that harmonises them is harmonising, not reporting.
🔍 The Pramana Question
Much of the difference between the schools reduces to a single technical question: how many valid means of knowledge are there? Every school answers it, and the answer determines what else it can say.
| School | Pramanas accepted |
|---|---|
| Charvaka (nastika) | 1 — perception only |
| Vaisheshika | 2 — perception, inference |
| Samkhya, Yoga | 3 — perception, inference, verbal testimony |
| Nyaya | 4 — the above plus comparison (upamana) |
| Prabhakara Mimamsa | 5 — plus postulation (arthapatti) |
| Bhatta Mimamsa, Advaita Vedanta | 6 — plus non-apprehension (anupalabdhi) |
💡 Why the count matters
A school that accepts only perception cannot argue for an unseen self. A school that accepts verbal testimony can treat the Veda as evidence. A school that accepts anupalabdhi — the knowledge of absence, that there is no pot on the floor — can make claims about what is not the case. The pramana list is not a preliminary; it is the constitution of each system.
⚔️ The Schools They Argued With
The six did not develop in isolation. Their central texts are shaped, often line by line, by argument against three nastika schools:
- Buddhism — the most sustained opponent, and the one that forced the most development. The doctrines of momentariness, of no-self (anatman) and of shunyata are answered directly in Nyaya, Mimamsa and Vedanta texts.
- Jainism — with its own theory of the soul, its anekantavada (many-sidedness) and its distinctive account of karma as material.
- Charvaka / Lokayata — materialist, accepting only perception, denying the afterlife and the authority of the Veda. Its own texts are lost; it is known almost entirely through the refutations of it, which is worth remembering when reading them.
📚 Where They Stand Now
The six are not equally alive. An honest account of their present state:
| School | Status |
|---|---|
| Vedanta | Overwhelmingly the dominant survivor. Its three main sub-schools have living institutions, lineages and mathas. |
| Yoga | Alive globally, though usually detached from its Samkhya metaphysics and reduced to the third and fourth limbs. |
| Nyaya | Alive as a discipline in traditional pathashalas; the later Navya-Nyaya logic remains technically formidable and is studied. |
| Mimamsa | Survives in ritual practice and in the interpretation of Dharmashastra; few independent practitioners. |
| Samkhya | Absorbed — its vocabulary is everywhere, in the Gita, the Puranas and Yoga, but almost no one is a Samkhyan. |
| Vaisheshika | Merged into Nyaya-Vaisheshika; not independently maintained. |
📌 The thing worth taking away
A tradition that produced six mutually incompatible orthodoxies, each with a formal obligation to state its opponents' case properly, is not a tradition of unquestioned belief. Darshana means a way of seeing, and the plural in shad darshana is the point.
❓ Frequently Asked Questions
What does astika really mean?
Accepting the Veda as a valid means of knowledge — a pramana. It is routinely mistranslated as “theistic,” and in this classification that is wrong. Which is why Samkhya (explicitly nirishvara, without a Lord) and Purva Mimamsa (the Veda authorless and eternal, needing no God to issue it) are both astika without being theistic.
What are the six darshanas?
Nyaya (logic and valid knowledge), Vaisheshika (categories of what exists; atomism), Samkhya (the 25 tattvas; purusha and prakriti), Yoga (stilling the mind), Purva Mimamsa (dharma and the Vedic injunction), and Uttara Mimamsa / Vedanta (Brahman and the Upanishads).
Why are the six darshanas paired?
In each pair one system supplies the metaphysics and the other the method. Vaisheshika says what exists, Nyaya says how we know it — they merged into Nyaya-Vaisheshika. Samkhya supplies the analysis, Yoga the practice, Patanjali taking Samkhya's metaphysics almost entire and adding Ishvara. Purva and Uttara Mimamsa are two halves of one enquiry into the Veda — ritual and dharma, then Upanishads and Brahman.
How many pramanas does each school accept?
Charvaka 1 (perception); Vaisheshika 2 (+inference); Samkhya and Yoga 3 (+verbal testimony); Nyaya 4 (+comparison); Prabhakara Mimamsa 5 (+postulation); Bhatta Mimamsa and Advaita 6 (+non-apprehension). The count is the constitution of each system — a school accepting only perception cannot argue for an unseen self.
Which of the six darshanas are still practised?
Vedanta is overwhelmingly the dominant survivor. Yoga is alive globally, usually detached from its Samkhya metaphysics. Nyaya survives as a discipline in traditional pathashalas. Mimamsa survives in ritual practice and Dharmashastra interpretation. Samkhya has been absorbed — its vocabulary is everywhere but almost no one is a Samkhyan. Vaisheshika merged into Nyaya-Vaisheshika.
🙏 Conclusion
The six darshanas share one commitment — the Veda as a means of knowledge — and disagree about almost everything that follows from it, including whether there is a God, whether the world is real, how many selves there are, and whether liberation is even the goal. They were written as aphorisms, argued through commentaries, and required to state the opposing case first. That structure, more than any single conclusion, is what the six actually amount to.
