Samkhya means enumeration, and the school is named for what it does: it counts. Reality comes to twenty-five principles, and the whole system turns on the fact that twenty-four of them are unconscious and active, and one is conscious and does nothing at all. Bondage, on this account, is a case of mistaken identity between the two.
🔢 Samkhya at a Glance
Founder: Kapila, traditionally; the classical text is Ishvarakrishna's Samkhya Karika
Tattvas: 25 — 1 purusha + 24 belonging to prakriti
Dualism: purusha (conscious, inactive, plural) vs prakriti (unconscious, active, one)
Gunas: sattva, rajas, tamas — the constituents of prakriti
Causation: satkaryavada — the effect pre-exists in the cause
God: classical Samkhya is nirishvara — without a Lord
📑 Table of Contents
☯️ Purusha and Prakriti
| Purusha | Prakriti | |
|---|---|---|
| Nature | Pure consciousness | Unconscious material principle |
| Activity | Entirely inactive — a witness only | Ceaselessly active, evolving |
| Number | Plural — innumerable, one per being | One, single and universal |
| Change | Unchanging, eternal | Constantly transforming |
| Constituents | None; partless | The three gunas in equilibrium |
📌 The plurality of purushas
This is where Samkhya breaks decisively with Advaita, and its argument is simple: if there were only one purusha, then when one person was liberated all would be, and when one was born all would be born. Since people are born and die and are liberated separately, the purushas must be many. The Karika states the argument directly.
💡 The two similes
Samkhya explains how an inactive witness and an unconscious agent can cooperate with two images the tradition never stopped quoting:
The lame man and the blind man. Prakriti is blind — active but without awareness. Purusha is lame — aware but unable to act. Neither escapes the forest alone; the blind man carries the lame man, who directs. Their association is functional, not a merger.
The dancer. Prakriti performs for the purusha as a dancer performs for an audience — and, having been seen, ceases. The Karika adds a striking line: nothing is more modest than prakriti, who, once she knows she has been seen, does not show herself again.
🌀 The Three Gunas
Prakriti is not a stuff but a balance. It consists of three gunas — strands, or constituents — which are present in everything material and whose changing proportions account for all difference.
| Guna | Character | Function | Manifests as |
|---|---|---|---|
| Sattva | Light, buoyant, illuminating | Reveals | Clarity, knowledge, calm, joy |
| Rajas | Stimulating, mobile | Activates | Motion, desire, restlessness, pain |
| Tamas | Heavy, obstructing | Restrains | Inertia, delusion, sleep, concealment |
In their equilibrium prakriti is unmanifest — nothing happens. When the equilibrium is disturbed, in the presence of purusha, evolution begins. The Karika is careful: the gunas mutually dominate, support, produce and consort with one another, so no guna acts alone.
🔢 The Twenty-Five
The evolution proceeds in a fixed order, each stage producing the next:
| Order | Tattva | Note |
|---|---|---|
| 1 | Purusha | Neither produced nor productive |
| 2 | Prakriti (mula-prakriti) | Productive, not produced |
| 3 | Mahat / Buddhi — intellect | The first evolute; determination, decision |
| 4 | Ahamkara — I-maker | The sense of being an agent; the root of the mistake |
| 5 | Manas — mind | The coordinating internal organ |
| 6–10 | Jnanendriyas | Ear, skin, eye, tongue, nose — the senses of knowledge |
| 11–15 | Karmendriyas | Speech, hands, feet, excretion, generation — the organs of action |
| 16–20 | Tanmatras | Sound, touch, form, taste, smell — the subtle elements |
| 21–25 | Mahabhutas | Ether, air, fire, water, earth — the gross elements |
📌 Notice the direction
Intellect comes first, before mind and long before matter. The gross elements are the last things to appear, produced from subtle elements which are themselves produced from the ego. Samkhya's world evolves from the psychological to the physical, not the other way round — which is precisely the reverse of a materialist cosmology, and is why the system is not one.
🔓 Bondage, Liberation, and the Missing God
Bondage is not caused by anything happening to purusha, because nothing can happen to purusha. It is a case of mistaken identity: the intellect, being sattvic and reflective, reflects consciousness, and the purusha appears to be an agent that acts and suffers. It never was.
Liberation, kaivalya — “aloneness” — is therefore the ending of a misidentification rather than an achievement. It comes from discriminative knowledge, viveka-khyati: seeing that purusha is not prakriti. The Karika's formulation is exact and famous: no one is bound, no one is liberated, and no one transmigrates; it is prakriti alone, in her various forms, who is bound, transmigrates and is released.
On Samkhya having no God. Classical Samkhya as set out in the Samkhya Karika is nirishvara — it neither asserts nor requires a creator. The reasoning is internal: prakriti's evolution is automatic once equilibrium is disturbed, purusha is by definition inactive, and a God would be either purposeless (if complete) or deficient (if he had purposes). Nothing in the system needs one.
Samkhya is nonetheless classified as astika, because that word means accepting the Veda's authority — not accepting a God. And Yoga, which takes Samkhya's metaphysics almost unchanged, does admit Ishvara — as a special purusha untouched by affliction, and as an object of devotion rather than a creator.
💡 Satkaryavada
Samkhya's theory of causation holds that the effect pre-exists in its cause — oil is already in the sesame, the pot already in the clay, and production is manifestation rather than creation. The arguments: nothing can be made from nothing; a specific cause is needed for a specific effect; not everything can come from anything. This is why prakriti can contain the whole world before evolving it, and it is the deepest disagreement between Samkhya and Nyaya-Vaisheshika, which holds the opposite (asatkaryavada).
❓ Frequently Asked Questions
What are purusha and prakriti?
The two irreducible principles. Purusha: pure consciousness — entirely inactive, a witness only, unchanging, and plural, one per being. Prakriti: the unconscious material principle — ceaselessly active, transforming, and single, consisting of the three gunas in equilibrium.
Why does Samkhya say there are many purushas?
Because if there were only one, when one person was liberated all would be, and when one was born all would be. Since people are born, die and are liberated separately, the purushas must be many. The Karika states the argument directly — and it is where Samkhya breaks decisively with Advaita.
Does Samkhya believe in God?
Classical Samkhya is nirishvara — without a Lord. Prakriti's evolution is automatic once equilibrium is disturbed, purusha is by definition inactive, and a God would be purposeless if complete or deficient if he had purposes. It is still astika, because that means accepting the Veda's authority, not a God. Yoga, taking the same metaphysics, does admit Ishvara — as a special purusha, an object of devotion rather than a creator.
What are the twenty-five tattvas?
Purusha and prakriti, then 23 evolutes in fixed order: mahat/buddhi (intellect), ahamkara (I-maker), manas, the 5 senses of knowledge, the 5 organs of action, the 5 tanmatras, and the 5 gross elements. Notice the direction: intellect first, gross matter last — Samkhya's world evolves from the psychological to the physical, the reverse of a materialist cosmology.
What is satkaryavada?
Samkhya's causation theory: the effect pre-exists in its cause. Oil is already in the sesame, the pot in the clay — production is manifestation, not creation. Because nothing can come from nothing, a specific cause is needed for a specific effect, and not everything can come from anything. It is why prakriti can contain the world before evolving it, and the deepest split with Nyaya-Vaisheshika, which holds the opposite.
🙏 Conclusion
Samkhya counts to twenty-five, and the entire drama lies in the gap between the twenty-four that act without knowing and the one that knows without acting. Its world evolves from intellect down to earth, its bondage is a misreading rather than a captivity, and its liberation is described as a dancer leaving the stage because she has been seen. It has almost no adherents today and its vocabulary is everywhere — in the Gita, the Puranas, Ayurveda and every yoga class that mentions the gunas.
