Samkhya

Sāṃkhya is the counting school — the project of enumerating, with rigor, the constituent principles of experience so that the student can perform the central discriminative act on which the entire path turns: distinguishing puruṣa from prakṛti.

The two ontological categories

The metaphysics is austere. There are exactly two ultimate categories:

• Puruṣa — the witness. Pure consciousness, attribute-less (nirguṇa), inactive, unchanging. Plural — each apparent individual is its own puruṣa (this is the key disagreement with later [[advaita-vedanta|Advaita Vedānta]], which treats consciousness as ultimately singular). Puruṣa does nothing; it only witnesses.
• Prakṛti — manifest nature. The substance of which everything experienceable is made — including the body, the senses, the mind, and the intellect. Prakṛti is composed of three guṇas (qualities or strands): sattva (lightness, clarity, luminosity), rajas (activity, restlessness, energy), and tamas (heaviness, dullness, inertia). All phenomena are prakṛti’s shifting balances of these three.

The whole experienced world is therefore prakṛti; puruṣa is what witnesses prakṛti without participating in it. Suffering arises because the puruṣa — through some originary confusion the school does not satisfyingly explain — mistakes itself for some configuration of prakṛti (the body, the mind, the personality). Liberation (kaivalya, isolation) is the viveka — the discriminative recognition — that the witness is not the witnessed.

The 25 tattvas — the enumeration

The school’s name comes from this enumeration. Sāṃkhya counts:

1. Puruṣa — pure consciousness (witness).
2. Prakṛti — the unmanifest substrate of nature.
3. Mahat (buddhi) — the great principle, intellect; the first product of prakṛti.
4. Ahaṃkāra — the I-maker, ego-principle. 5–9. The five jñānendriyas — sense-organs of knowledge (hearing, touch, sight, taste, smell). 10–14. The five karmendriyas — organs of action (speech, hands, feet, generation, elimination).
5. Manas — the coordinating mental faculty. 16–20. The five tanmātras — subtle elements (sound, touch, form, taste, smell). 21–25. The five mahābhūtas — gross elements (space, air, fire, water, earth).

This produces the canonical 25: one puruṣa, one prakṛti, and 23 emergent principles. The unfolding is causal — prakṛti gives rise to mahat, mahat to ahaṃkāra, ahaṃkāra to the senses and the subtle elements, the subtle elements to the gross. Each step is a coarsening; each tattva is a more concretized expression of the prior.

The guṇas

The three guṇas are not adjectives describing things; they are the constituents from which prakṛti’s products are composed. Every object, mental state, body, food, action, season has its guṇa-balance:

• Sattva — light, luminous, harmonious, conducive to clarity and contemplation.
• Rajas — restless, active, passionate, driving.
• Tamas — heavy, dull, obscuring, inertial.

The guṇas are never absent; they are present in different ratios. Yogic practice — and Āyurvedic medicine, which inherits this vocabulary — is largely the cultivation of sattva and the disciplined relationship to rajas and tamas.

The foundational text

The Sāṃkhya-Kārikā of Īśvarakṛṣṇa (c. 350–450 CE) — 72 verses (kārikās) — is the foundational extant text. It is unusually clean philosophy: definitions, proofs, enumeration, exposition of the path. Earlier Sāṃkhya material is preserved indirectly (the school had a substantial pre-classical existence; Kapila is the traditional founder); later commentaries (Gauḍapāda’s Bhāṣya, Vācaspati Miśra’s Sāṃkhya-tattva-kaumudī) elaborate on it. The Sāṃkhya Sūtras, traditionally attributed to Kapila, are later (c. 14th c.) and reflect a school in transition.

Atheism, plural-puruṣa, and the divergence from Yoga

A peculiarity of classical Sāṃkhya: it is atheistic. The school does not require, and the Sāṃkhya-Kārikā does not posit, a creator-god. Prakṛti unfolds by its own internal logic (the imbalance of the guṇas); no divine agency is required. This sets Sāṃkhya apart from Yoga, which does posit Īśvara — a special puruṣa, the Lord — and recommends Īśvara-praṇidhāna (surrender to Īśvara) as a practice.

The two schools also disagree on the plurality of puruṣa — both maintain it, but [[advaita-vedanta|Advaita Vedānta]]‘s eventual displacement of Sāṃkhya as the dominant philosophical school happens partly through Advaita’s argument that an infinite plurality of puruṣas is metaphysically extravagant; the singular Brahman is simpler.

Why this matters for yoga

Patañjali’s [[yoga-sutras|Yoga Sūtras]] do not develop their own metaphysics; they presume Sāṃkhya’s. The puruṣa / prakṛti distinction, the guṇa theory, the tattva enumeration — all are imported. The Yoga Sūtras read most coherently with the Sāṃkhya-Kārikā held in the other hand. Patañjali’s contribution is the method: the sādhana by which the discriminative recognition Sāṃkhya names is actually achieved.

This is why the two are conventionally called Sāṃkhya-Yoga together: theory and practice, darśana and anuṣṭhāna.

Sāṃkhya in contemporary discourse

The school is no longer practiced as an independent tradition, but its vocabulary is everywhere:

• Yoga — the entire framework of Patañjali, plus the guṇa language ubiquitous in contemporary yoga teaching.
• Āyurveda — the dośa theory (vāta, pitta, kapha) extends Sāṃkhya’s principles into clinical medicine; the guṇas are central to Āyurvedic diagnosis.
• Bhagavad Gītā — uses Sāṃkhya language constantly; chapters 13, 14, and 18 are particularly Sāṃkhya-saturated.
• Tantra and haṭha — extend the Sāṃkhya tattvas (sometimes to 36 in non-dual Śaiva tantra; the medieval haṭha texts use the guṇa framework for the energetic body).
