Purusha

Samkhya's twenty-five tattvas divide sharply into two kinds of thing, and purusha is the whole of one kind by itself. The other twenty-four form a single chain: prakriti unfolds into intellect, intellect into ego, ego into mind and the ten organs and the five subtle elements, and the subtle elements harden into the five gross elements that make up the physical world. Every link in that chain is prakriti in a different guise, and every link can in principle be traced back to the equilibrium of the three gunas disturbed at the start of a cosmic cycle. Purusha is not a link. It does not evolve from prakriti, nothing evolves from it, and it is not made of the gunas at all.

What purusha contributes to the twenty-five is presence rather than substance. Samkhya's classical image is a dancer performing before a seated audience: prakriti is the dancer, purusha is pure witnessing, and the appearance that purusha is involved in the performance comes only from proximity, the way iron near a magnet seems to move on its own. Multiple purushas are posited, one for each apparently separate stream of experience, which is itself one of the system's more debated commitments, since an inactive plural consciousness raises the question of what distinguishes one purusha from another if none of them does or has anything.

Counting purusha as the first of the twenty-five tattvas, alongside twenty-four items that are all stages of one unfolding substance, is the clearest sign of what the enumeration is actually for. It is not a list of ingredients in the world; it is a map of everything that exists, sorted into the one thing that watches and the twenty-four things, all continuous with each other, that are watched.

If purusha never acts and is never changed by anything, the Samkhya account of bondage and liberation cannot be the ordinary story of a self trapped by matter and then freed from it, because nothing about purusha was ever actually altered in the first place. What the system describes instead is a case of mistaken identity. Purusha appears to suffer, to desire, to be born and to die only because it is mistaken for the intellect, the ego and the mind, the finest and most purusha-like layers of prakriti, which do think, desire and change. Bondage, on this account, is purusha failing to distinguish itself from those layers; liberation is purusha, through the discriminative insight the whole system exists to cultivate, recognising that it was never the one thinking or suffering at all.

This is why Samkhya's liberation, kaivalya, is described as isolation rather than union or extinction: purusha is not merged into anything greater, nor does it stop existing, it simply stands recognised as what it always was, uninvolved. The classical simile carries the point past the point of subtlety needed: a dancer who has been thoroughly seen has nothing left to perform, and withdraws; prakriti, once purusha's discrimination is complete, ceases to unfold for that purusha specifically, though it goes on producing appearances for every purusha that has not yet seen through it.

The system needs no god to accomplish this and states plainly that it has none, since the work is epistemic rather than devotional: getting a true description of what is which. That is also why Samkhya's vocabulary, purusha and prakriti above all, was borrowed wholesale by traditions that do posit a creator and had to refit the terms to a theology Ishvarakrishna's text never assumed.
