A samskara is a subtle psychological impression left behind by an action, thought, or experience, stored in the causal body discussed earlier in this series, and the underlying image the tradition returns to repeatedly is a groove: a single pass leaves a shallow mark, but repetition, action performed the same way again and again, deepens that mark into a channel deep enough that future behaviour tends to run along it automatically, with progressively less conscious deliberation required each time.
This gives the tradition a mechanism for a fact that is otherwise puzzling on a purely conscious-decision model of behaviour: why a habit, once deeply established, continues to exert pull even after a person has consciously decided to abandon it, and why certain tendencies, fears, or attractions seem to arise in a person from early childhood or even, the tradition would argue, from a prior lifetime, without any traceable origin in the person’s own conscious experience of this life. Samskaras accumulated across a long history, personal and, on the reincarnation model, trans-lifetime, are held to be operating well beneath the level of conscious decision-making at any given moment.
This is also the mechanism connecting sanchita karma, the total accumulated stock, to actual, observable personality and behaviour: sanchita is not simply an abstract ledger sitting apart from the mind. It is stored specifically as samskaras, grooves cut into the causal body, which is precisely why disciplined practice aimed at loosening old patterns, meditation, repeated right action, conscious redirection of habitual response, is treated as capable of genuinely working on accumulated karma rather than merely managing its symptoms.
Samskaras that have deepened enough to become persistent, recurring patterns of desire or aversion receive their own specific name in the tradition, distinguishing a general impression from the specific, often stubborn tendency it eventually produces, which is the subject of the next piece.
