saṅkhāra
Formations
[ sun-KAA-ra ]
Seeing it in life
As an aggregate, saṅkhāra-khandha covers all mental factors except feeling and perception. More broadly, saṅkhāra means anything conditioned.
In short
Volitional formations — the 50 cetasikas other than vedanā and saññā.
The analysis
Saṅkhāra does double duty in the texts. As the fourth khandha, it names every cetasika except vedanā and saññā — fifty of the fifty-two mental factors, the machinery of intention, effort, and disposition, bundled under one heading. As the second link of dependent origination, it names the volitional formations that ignorance conditions and that in turn shape consciousness. Both senses share a root idea: saṅkhāra is what gets put together, and what puts together.
Where it sits
Avijjā → saṅkhāra → viññāṇa: not-knowing conditions the formations that shape the character of the next consciousness. This is the link most associated with kamma-formation proper — the habitual grooves a mind runs in, reinforced each time they're used. A habitual money-anxiety response is saṅkhāra in the practical sense: not a single thought, but an assembled pattern that has been run often enough to run itself.
The reach for the banking app before the eyes are fully open — that's not a decision made fresh each morning. It's a formation, assembled from many prior mornings, running with less and less friction each time it fires.
Commonly mistaken for
Willpower or effort in the positive sense only. Saṅkhāra includes unwholesome formations too — habitual reactivity is as much a saṅkhāra as habitual discipline.
Personality. Formations are patterns of conditioned repetition, not a fixed trait; the same mind can build new formations to replace old ones.
