9.3 — The Six Darshanas, Mapped
Darshana means "view" or "seeing" — from the root drish, to see. The word for a philosophical system in India is not "doctrine" or "school of thought" but "a way of looking."
And that is a useful thing to know before the list, because it explains why the six are treated as complementary rather than as rivals. A tradition that calls its systems "views" is less likely to require you to pick one.
Orthodox and heterodox
The first division, and it is not about belief in God.
Astika — usually translated orthodox — means accepting the authority of the Vedas.
Nastika — heterodox — means not accepting it.
And the crucial point: this has nothing to do with theism. Samkhya is atheistic and orthodox. Early Mimamsa is effectively atheistic and orthodox. Buddhism and Jainism are heterodox and both have elaborate metaphysics.
The dividing line is textual authority, not God, and that is a distinctive feature of the Indian philosophical landscape.
The six orthodox systems, and the three heterodox ones — Buddhism (Part 6), Jainism and Charvaka (9.10, 9.11).
The six, in pairs
They are traditionally given as three pairs, and the pairing is not arbitrary — each pair is a metaphysics plus its method.
Samkhya and Yoga
Samkhya — the oldest, and it is an analysis of what exists. Two ultimate categories: consciousness and matter. Atheistic in its classical form. 9.4.
Yoga — Patanjali's system. Accepts Samkhya's metaphysics almost entirely and supplies the practice. 9.5.
The pair: Samkhya says what the problem is, Yoga says what to do about it.
Nyaya and Vaisheshika
Nyaya — logic and epistemology. How do we know anything, what counts as valid reasoning, and what is a fallacy.
Vaisheshika — the analysis of what things are made of. An atomic theory.
The pair: Vaisheshika supplies the ontology, Nyaya supplies the method of establishing it. 9.6.
Mimamsa and Vedanta
Mimamsa — the interpretation of the ritual portion of the Vedas. How to read an instruction, and what makes an action obligatory. 9.7.
Vedanta — literally "the end of the Veda," meaning the Upanishads. The interpretation of the philosophical portion. 9.8 and 9.9.
The pair: two halves of one text, and two schools that ended up in deep disagreement about which half matters.
The question they are all answering
And this is what makes them a conversation rather than a list.
Every one of the nine systems is answering the same question, and the question is not "what is true."
It is: what is the cause of bondage, and how does it end?
Every school agrees that the ordinary human condition is one of being caught — in repetition, in suffering, in a cycle — and every school proposes a diagnosis and a route out.
Samkhya: you are caught because consciousness has mistaken itself for matter. Discrimination between the two frees you.
Yoga: the same, plus a graded practice for achieving the discrimination.
Nyaya: false knowledge causes attachment causes action causes rebirth. Correct knowledge, obtained by valid reasoning, breaks the chain at the first link.
Vaisheshika: understanding what things actually are removes the misapprehension.
Mimamsa: perform the prescribed actions correctly, without desire for their fruits — and note how close this is to the Gita's karma yoga (5.3).
Vedanta: you are caught by ignorance of what you actually are. Knowing "you are that" ends it (9.2, 9.8).
Buddhism: the grip causes it, and releasing the grip ends it (6.5).
Jainism: action accumulates a subtle matter that binds; austerity and non-harm remove it (9.11).
And Charvaka: you are not caught by anything, there is no cycle, this is the only life, and the whole framing is a fiction maintained by priests (9.10).
How the argument was conducted
One feature of Indian philosophy worth knowing, because it is unusual and admirable.
The standard format required you to state your opponent's position first, at full strength, before refuting it.
The purvapaksha — the prior position — is set out as well as its own proponents would state it, and frequently better. Then the refutation, then the conclusion.
Which means a great deal of what we know about lost schools comes from the works of their opponents, because the opponents stated their case properly. Charvaka's own texts are almost entirely lost and we know the system largely from the arguments against it (9.10).
This is a genuinely good intellectual norm and Volume VI's chapter on being your own devil's advocate is the modern version of the same discipline.
What each is best at
A practical map, because you will meet all six unevenly.
Samkhya: the clearest analysis of the difference between the observer and the observed. Read it if 5.5 interested you.
Yoga: the most usable practical system, and the one with the most direct modern descendants.
Nyaya: the most rigorous. India's logic, and it is real logic — a theory of inference, of valid means of knowledge, and a catalogue of fallacies that stands comparison with anything produced elsewhere before the modern period.
Vaisheshika: mostly of historical interest, though the atomism is striking.
Mimamsa: the least appealing and the most surprising, because its theory of how to read a text and how obligation works is sophisticated and it is where the "act without desire for the fruit" idea largely comes from.
And Vedanta: the one that won, and which most people mean when they say Indian philosophy.
What to carry from this page
Darshana means a way of looking, not a doctrine. A tradition that names its systems that way is less likely to demand you pick one.
Orthodox means accepting textual authority, not believing in God. An atheistic system sits comfortably on the orthodox side.
All nine are answering one question — what causes the bondage and how does it end — which is why they can be compared at all.
And state your opponent's case at full strength before refuting it. That was the required format, and it is why we still have the arguments of schools whose own books are gone.
Next: 9.4 — the oldest system, which counts the components of existence and arrives at a conclusion that is both atheistic and profoundly strange.
