Sāṃkhya

Two realities and no more: a witnessing consciousness that never changes, and a nature that never stops changing. The oldest of the classical schools, and the quiet grammar behind the Gītā, the Purāṇas, Yoga and Āyurveda.

If you have ever heard that the world is made of three guṇas, that the mind is subtler matter rather than spirit, or that the true Self only watches while nature acts, you have already met Sāṃkhya. Its name probably means “enumeration” — the school that counts out the principles (tattvas) of reality, one by one, until the knower can say exactly what he is not.

Sāṃkhya view This page presents classical Sāṃkhya in its own terms, as its teachers argued it; rival schools’ objections are gathered in the box further down.

Kapila, Īśvarakṛṣṇa and the texts

Tradition names the sage Kapila as the founder, and remembers him with awe. The Śvetāśvatara Upaniṣad (5.2) speaks of a “seer, kapila” — the tradition hears the founder’s name, though many scholars read “the tawny one,” i.e. Hiraṇyagarbha; the epics tell how his glance burned the sixty thousand sons of King Sagara to ash; and in the Bhāgavata Purāṇa (Book 3) Kapila is an avatāra of Vishnu who teaches a devotional Sāṃkhya to his own mother, Devahūti — so that one of the classic expositions of the system is addressed to a woman, who attains liberation by it. Tradition names his pupil Āsuri and Āsuri’s pupil Pañcaśikha as the next teachers.

Historians see a longer growth. Sāṃkhya-like ideas — a ladder of senses, mind, intellect and the “unmanifest” leading up to the Person — appear in the Kaṭha Upaniṣad and in the philosophical books of the Mahābhārata, and the Buddhist poet Aśvaghoṣa (1st–2nd century CE) has the Buddha’s early teacher Arāḍa expound something close to it. An older treatise, the Ṣaṣṭitantra (“system of sixty topics”), is lost. What survives as the classic statement is a short verse text:

  1. c. 800–200 BCEProto-SāṃkhyaHierarchies of principles in the Kaṭha and Śvetāśvatara Upaniṣads, and dialogues in the Mahābhārata’s Mokṣadharma.
  2. c. 350–450 CEThe SāṃkhyakārikāĪśvarakṛṣṇa sums up the system in about seventy verses. Dates are approximate.
  3. 6th c.To ChinaThe monk Paramārtha translates the Kārikā with a commentary into Chinese — evidence of how widely it was read.
  4. c. 6th–10th c.The commentariesGauḍapāda’s Bhāṣya, the long anonymous Yuktidīpikā, and Vācaspati Miśra’s Tattvakaumudī, the most studied in later centuries.
  5. c. 14th–16th c.A late revivalThe Sāṃkhya Sūtra, ascribed to Kapila but late, and Vijñānabhikṣu’s commentary, which draws Sāṃkhya close to Vedānta.

Why ask at all?

The Kārikā opens not with a metaphysical puzzle but with pain. Human beings are struck by three kinds of suffering — from within (illness, grief), from other beings, and from fate and the elements — and so they ask how to end it. Medicine and ritual help, but not for good: the pain returns. Sāṃkhya offers a remedy that is meant to be final, and that remedy is knowledge of what we are. Everything else in the system serves that aim.

How can such things be known? Sāṃkhya accepts three means of knowledge (pramāṇas): perception, inference and reliable testimony, including the Veda (Kārikā 4). Much of the system rests on inference, since its first principles cannot be seen.

Two realities

Sāṃkhya is a dualism. There are two utterly different kinds of reality, and neither can be reduced to the other.

The surprise for many readers is where the line falls. Your thoughts, feelings, memories and even your sense of “I” are all on the side of matter — subtle matter, but matter. Only the bare awareness that witnesses them is puruṣa. One verse sets out the whole scheme:

मूलप्रकृतिर्अविकृतिर्महदाद्याः प्रकृतिविकृतयः सप्त ।
षोडशकस्तु विकारो न प्रकृतिर्न विकृतिः पुरुषः ॥ mūla-prakṛtir avikṛtir mahad-ādyāḥ prakṛti-vikṛtayaḥ sapta,
ṣoḍaśakas tu vikāro na prakṛtir na vikṛtiḥ puruṣaḥ Root nature is no product. The seven beginning with the great one are both sources and products. The sixteen are products only. Puruṣa is neither source nor product. Sāṃkhyakārikā 3

The effect is already in the cause

Why believe in one hidden primal nature at all? Sāṃkhya’s answer rests on its theory of causation, satkāryavāda: the effect already exists, unmanifest, in its material cause. Pot is in clay before the potter works; oil is in sesame before the press. Making is not creating something from nothing, but bringing out what was there.

असदकरणाद्उपादानग्रहणात्सर्वसम्भवाभावात् ।
शक्तस्य शक्यकरणात्कारणभावाच्च सत्कार्यम् ॥ asad-akaraṇād upādāna-grahaṇāt sarva-sambhavābhāvāt,
śaktasya śakya-karaṇāt kāraṇa-bhāvāc ca sat-kāryam The effect exists [beforehand]: because what does not exist cannot be produced; because a definite material is taken up; because not everything arises from everything; because a capable cause makes only what it is capable of; and because the effect is of the nature of its cause. Sāṃkhyakārikā 9

No one presses sand for oil. If every effect lies latent in its cause, then the whole manifest world — bodies, minds, mountains — must lie latent in some ultimate cause. Trace effects back far enough, and you reach avyakta, “the unmanifest”: prakṛti with its three guṇas in perfect balance. Creation begins when that balance is disturbed; dissolution (pralaya) is the return to it.

Every school had to answer this argument. Try the classic debate:

The potter’s question

Is the pot already in the clay?

A potter shapes a lump of clay into a pot. Has something new come into being — or has something hidden come out?

Who won?

No one, finally. Sāṃkhya’s theory of real transformation passed into much of Vedānta and the Purāṇas; Nyāya kept the new-whole view; Advaita reworked Sāṃkhya’s argument into its own. The debate is still a good test of what you mean by “making.”

How the world unfolds

When prakṛti stirs in the presence of puruṣa, it unfolds in a fixed order, from the subtlest to the grossest. The Kārikā gives the sequence in a single verse (22). Step through it — note that the cosmic and the psychological are one process: the same steps make a universe and a mind.

Count them: prakṛti, intellect, I-maker, mind, ten capacities, five subtle and five gross elements — twenty-four — and puruṣa makes twenty-five. The Shaiva traditions later kept these twenty-five and added eleven higher principles above them, for thirty-six in all (see Shaiva Siddhanta and Kashmir Shaivism).

The lame man and the blind man

A hard question follows. If puruṣa does nothing and prakṛti knows nothing, how do they ever meet, and why does nature unfold? The Kārikā answers with its most famous image:

पुरुषस्य दर्शनार्थं कैवल्यार्थं तथा प्रधानस्य ।
पङ्ग्वन्धवदुभयोरपि संयोगस्तत्कृतः सर्गः ॥ puruṣasya darśanārthaṃ kaivalyārthaṃ tathā pradhānasya,
paṅgv-andhavad ubhayor api saṃyogas tat-kṛtaḥ sargaḥ For puruṣa to see, and for nature to bring about [puruṣa’s] aloneness, the two come together, like a lame man and a blind man; and from their union, creation arises. Sāṃkhyakārikā 21

The commentators tell the story: a lame man and a blind man are left behind in a forest. The blind man can walk but cannot see; the lame man can see but cannot walk. So the lame man rides on the blind man’s shoulders, and together they reach the village. Puruṣa supplies the light; prakṛti supplies the movement. Neither alone can make an experience.

But how can unconscious nature act for anyone? The Kārikā compares it to milk, which flows unknowingly for the growth of the calf (57). Nature works, without knowing it, for the experience and the release of puruṣa. And when the work is done, it stops:

रङ्गस्य दर्शयित्वा निवर्तते नर्तकी यथा नृत्यात् ।
पुरुषस्य तथात्मानं प्रकाश्य विनिवर्तते प्रकृतिः ॥ raṅgasya darśayitvā nivartate nartakī yathā nṛtyāt,
puruṣasya tathātmānaṃ prakāśya vinivartate prakṛtiḥ As a dancer stops dancing once she has shown herself to the audience, so nature withdraws once she has revealed herself to puruṣa. Sāṃkhyakārikā 59

A later verse adds that nothing is shyer than prakṛti: once she knows “I have been seen,” she never again comes before that puruṣa’s gaze (61).

Liberation: standing alone

Bondage, for Sāṃkhya, is a mistake of identity. The intellect, being the clearest form of matter, takes on the light of consciousness, and consciousness seems to take on the colour of the intellect’s states. So we say “I am suffering,” when suffering is a state of buddhi, merely witnessed. Strictly, the Kārikā says, no puruṣa is ever bound, freed or reborn; it is prakṛti, in her many forms, that is bound and freed (62). The subtle body carries the impressions from life to life — see Samsara & Moksha — while puruṣa never moves at all.

The cure is discriminating knowledge, vivekakhyāti: the clear seeing that “I am not this.”

एवं तत्त्वाभ्यासान्नास्मि न मे नाहमित्यपरिशेषम् ।
अविपर्ययाद्विशुद्धं केवलमुत्पद्यते ज्ञानम् ॥ evaṃ tattvābhyāsān nāsmi na me nāham ity apariśeṣam,
aviparyayād viśuddhaṃ kevalam utpadyate jñānam Thus, from practice of the principles, arises the knowledge “I am not; nothing is mine; there is no I” — complete, pure because free of error, and solitary. Sāṃkhyakārikā 64

The “I” that is denied here is ahaṃkāra, not puruṣa: what falls away is every claim of matter to be the self. The result is kaivalya, “aloneness” — not loneliness, but consciousness no longer entangled. The body may go on for a while, as a potter’s wheel keeps spinning after the push has stopped (67); at death, the separation is final.

A world without a creator

Classical Sāṃkhya has no place for a creator God, and its commentators argue the point. An unchanging Lord could not act; a Lord who acted from desire would not be perfect; and nature, which unfolds by its own laws for the sake of puruṣa, needs no one to steer it. This is why the school is often called nirīśvara, “without Īśvara,” and why Time & Cosmology notes that for Sāṃkhya, nature itself unfolds and folds back without a maker. It is not materialism: the school affirms the Veda and countless conscious selves. It simply finds no work for a world-maker to do.

Not every Sāṃkhya agreed. The Mahābhārata’s Sāṃkhya teachings and the Bhāgavata’s Kapila set the twenty-five principles inside a theistic frame, and the later Sāṃkhya Sūtra says only that Īśvara is “not proven.” Its commentator Vijñānabhikṣu (16th century) argued that this was a debating concession, and that Sāṃkhya, Yoga and Vedānta finally agree. Yoga, its sister school, added Īśvara openly — see Yoga as Philosophy.

How other schools answered
  • Vedānta treated Sāṃkhya as its chief rival — Shankara likened refuting it to throwing the chief wrestler, after whom the rest fall easily. The Brahmasūtra argues that the Upaniṣads’ first cause “thought” or “saw” before creating, which unconscious matter cannot do (1.1.5), and that order and design cannot come from an unconscious cause:
    रचनानुपपत्तेश्च नानुमानम् ॥ racanānupapatteś ca nānumānam And the inferred [nature] is not [the cause], because design cannot be explained [from it]. Brahmasūtra 2.2.1
    Sāṃkhya’s reply is its milk and calf: unconscious things do act purposively, as milk nourishes the calf.
  • Nyāya-Vaiśeṣika rejected satkāryavāda for asatkāryavāda, and argued that the world, being made of parts, needs an intelligent maker (see Nyaya & Vaisheshika).
  • Advaita also asked: if puruṣas are many, what divides them? Consciousness without qualities cannot differ from consciousness without qualities — so there is only one Self (Advaita Vedanta).
  • Buddhists rejected both a permanent nature and permanent selves.

A quiet giant

Sāṃkhya has almost no living school of its own, yet few ideas have travelled further. The Bhagavad Gītā calls one of its teachings “sāṅkhya” (2.39) and is soaked in its vocabulary: “all actions are done by the guṇas of nature; the one deluded by the I-maker thinks, ‘I am the doer’” (3.27) — though the Gītā places both nature and spirit under Krishna (see The Bhagavad Gita). The Purāṇas tell creation as prakṛti unfolding into mahat, ahaṃkāra and the elements, now under God’s direction. Āyurveda, in the Caraka Saṃhitā, builds its picture of the person on a Sāṃkhya-like scheme, and the guṇas still shape how many Hindus think of food and temperament. Yoga takes over its metaphysics almost whole; the Tantras and Shaiva schools extend its ladder.

Living lineage One small monastic line still identifies itself with Sāṃkhya-Yoga: the Kāpil Maṭh at Madhupur in Jharkhand, founded by Swami Hariharānanda Āraṇya (1869–1947), whose commentary on the Yoga Sūtra is still read.

Check your understanding:

Quick check

For Sāṃkhya, the intellect (buddhi) belongs to…

It is the first product of nature — the subtlest matter, but matter. Only bare consciousness is puruṣa.

“Oil comes from sesame, not from sand” illustrates…

The effect pre-exists in its specific material cause (Kārikā 9).

In the image of the lame man and the blind man, the lame man is…

Consciousness gives sight; nature gives movement (Kārikā 21).

How many puruṣas does classical Sāṃkhya teach?

Many — one for each being. This is a main point where Advaita disagrees.

Questions people often ask

Is Sāṃkhya atheist?

Classical Sāṃkhya is non-theistic: it denies a creator, but it is not materialist, and it accepts the Veda as a means of knowledge. Theistic forms existed before and after it, and Yoga added Īśvara. “Atheist” in the modern sense misleads more than it helps.

How is puruṣa different from the Ātman of Advaita?

Both are pure, actionless consciousness. But Sāṃkhya’s puruṣas are many and stand over against a real nature; Advaita’s Ātman is one, identical with Brahman, and the world is its appearance. See Atman & Brahman.

If the mind is matter, is Sāṃkhya like modern materialism?

Only halfway. Like a neuroscientist, Sāṃkhya treats thinking, feeling and the sense of self as natural processes. Unlike materialism, it insists that none of them is aware: awareness is a second, irreducible reality. That is exactly why its teachers thought it could free us.

॥ Pause and reflect

  1. Notice a feeling you have right now. Can you also notice the awareness of it? Are they the same?
  2. Sāṃkhya says nature works “for” us without knowing it, as milk flows for the calf. Does that image comfort or puzzle you?
  3. The final knowledge begins with “I am not.” What would you have to stop claiming as yourself?
