Purusha

Literally “person” or “man”; philosophically, consciousness itself — the conscious-witness pole of the Sankhya-Vedanta analysis, paired with prakriti (nature/matter). In the Gita’s Ch 13 synthesis, purusha is essentially kshetrajna (knower-of-the-field); the Advaitic reading identifies the ultimate purusha with Brahman/atman.

Overview

Purusha is the standard Indian philosophical term for consciousness as the witness-principle. Etymologically “person” or “man” (from pur = city, hence the one who dwells in the body-city — compare the nine-gated city image from 5.13). Philosophically, purusha is the pole contrasted with prakriti in classical Sankhya and in the Gita’s refinement of it.

Sankhya’s original scheme. Kapila’s Sankhya posited two independent fundamental realities:

• Purusha — pure consciousness, inactive, only witnessing
• Prakriti — unconscious creative nature, which does all the acting

Problems in this scheme: purusha doesn’t act but prakriti has no consciousness, so how does action start? Sankhya’s answer: the mere proximity of purusha to prakriti activates prakriti’s inherent gunas, and evolution of the universe proceeds. Awkward but logically consistent.

The Gita’s refinement. The Gita largely keeps Sankhya’s purusha-prakriti distinction as analytic framework but subsumes it under non-duality:

• Krishna is both purusha (13.2 = kshetrajna) AND prakriti (7.4–7.5 = both apara and para prakriti are mine).
• Both purusha and prakriti are beginningless, but both arise from Krishna (13.19).
• There are in fact many purushas on one reading — each jiva is a purusha tangled in a specific prakriti (many consciousnesses, one nature) — and then the Purushottama (the Supreme Purusha, Ch 15’s focus) is the ultimate consciousness in whom all this is grounded.

Gita 13’s precise treatment (13.19–13.23):

• 13.19: Prakriti and purusha are both anādi (beginningless). The modifications (vikāras) and the gunas arise from prakriti.
• 13.20: Prakriti is said to be the source of karya-kārana-kartṛtva — cause-and-effect and doership. Purusha is said to be the source of sukha-duḥkha-bhoktṛtva — experience of pleasure and pain.
• 13.21: puruṣaḥ prakṛti-stho hi bhuṅkte prakṛti-jān guṇān — “the purusha, seated in prakriti, experiences the gunas arising from prakriti.” The cause of good and bad births is attachment to the gunas.
• 13.22: There is in this body another, higher Purusha — Paramatman — the witness, the consenter, the sustainer, the enjoyer, the great Lord, the supreme Self.
• 13.23: “One who knows purusha and prakriti with the gunas — however one lives — is not born again.”

The jiva-purusha vs Supreme Purusha distinction. Ch 13 makes precise what was implicit earlier:

• Jiva-purusha — the individual conscious being, caught up in (sthita) prakriti’s gunas, experiencing pleasure and pain through attachment. This is what the ordinary person is at the vyavaharika level.
• Paramatman / Purushottama — the Supreme Purusha, the same consciousness but untouched by the gunas and modifications. Krishna at the paramarthika level.

At the Advaitic summit, the two are non-different; the jiva-purusha is identically the Paramatman once the identification-with-prakriti is dissolved. Jiva = Atman = Brahman; the split is maya-produced.

Purusha-Prakriti as the Gita’s unified analysis. Summary of the Gita’s development:

• Ch 7 (apara/para prakriti): two natures — 8-fold material + 1-fold conscious.
• Ch 13 (kshetra/kshetrajna, purusha/prakriti): refines with purusha as the kshetrajna side.
• Ch 14 (the three gunas): develops prakriti’s tri-partite structure.
• Ch 15 (Purushottama): names the Supreme Purusha explicitly, beyond the perishable (kshara) and imperishable (akshara) categories.

Ch 13’s purusha-discussion is where the Gita’s “two beginningless realities, both mine” synthesis is most sharply stated.
