Overview

Classical Samkhya is the formulation represented by Ishvarakrishna's Samkhyakarika (c. 350–450 CE). It distinguishes a plurality of conscious purushas from unconscious prakriti and explains liberation through discriminative knowledge of their difference. Kapila is the tradition's legendary founder; earlier ideas now called proto-Samkhya are antecedents, not the classical school itself.

Key ideas

  • Purusha and Prakriti: Classical Samkhya distinguishes many eternal purushas (pure, inactive consciousnesses) from a single eternal prakriti (active, unconscious nature). Their conjunction accounts for experience and the evolution of the manifest world.
  • Three Gunas: All of material nature is composed of three qualities (gunas): sattva (light, goodness), rajas (activity, passion), and tamas (darkness, inertia). Their interplay drives all change.
  • Discriminative Knowledge: Liberation (kaivalya) occurs when purusha recognizes its complete distinction from prakriti — 'I am not this body, these thoughts, these emotions.'

Questions engaged

  • Existence of the Self

    Sāṃkhya answers with a plurality of eternal conscious selves, the puruṣas, each distinct from the mind and body that unconscious prakṛti evolves: the self exists, but as a witness, not as the thinking and feeling person.

Influenced by

  • Vedic Philosophy

    Took from the Vedas and Upanishads the term puruṣa for the conscious self, together with the framework in which action binds one to rebirth and knowledge wins release.

Later connections

  • Yoga Philosophy Influenced by this tradition

    Vyāsa's commentary on the Yoga Sūtras draws on the Sāṃkhya teachers whose system Īśvarakṛṣṇa's Kārikā summarizes, which is the school's documented contact with the classical school; the dualism of puruṣa and prakṛti that Patanjali's sūtras already presuppose belongs to the older Sāṃkhya current that predates it.

  • Vedanta Reacted to this tradition

    Śaṅkara's Brahma-Sūtra commentary rejects Sāṃkhya's claim that unconscious prakṛti could produce an ordered cosmos, arguing that only conscious Brahman can be its source.
