अनिच्च

Anicca is Pali for impermanence, formed from the negative prefix an- and nicca (permanent, stable, constant). It is one of the three marks of existence (tilakkhaṇa) that the Buddha identified as characterizing all conditioned phenomena — along with dukkha (unsatisfactoriness) and anattā (non-self). The observation is disarmingly simple: nothing conditioned lasts. Every phenomenon — physical, mental, emotional — arises from causes, depends on conditions, and passes away when those conditions change. This includes the person observing it.

Buddhist philosophy is precise about the mechanism of suffering that anicca produces. The problem is not impermanence itself but the cognitive habit of treating impermanent things as if they were permanent — clinging to pleasant experiences that are already in the process of ending, resisting unpleasant experiences that are already in the process of ending, building a sense of stable selfhood on a foundation that is continuously shifting. Anicca, in this sense, is not a teaching about loss but a teaching about accurate perception. The suffering comes from misreading the situation.

The contemplation of anicca has a specific meditative form in Theravāda practice. S.N. Goenka's Vipassana tradition — now taught globally through a network of centers founded in his method — uses body-scanning meditation in which practitioners observe the arising and passing of physical sensations, coming to experiential (not merely intellectual) recognition of impermanence. This is thought to be continuous with the practice the Buddha himself described: seeing things as they actually are, moment by moment.

Western philosophy arrived at adjacent insights from different directions. Heraclitus declared that you cannot step into the same river twice — the river's permanence is a convention over a continuous flux. Hume's bundle theory of the self — that what we call 'I' is a bundle of perceptions with no underlying fixed observer — is structurally close to the Buddhist account of anicca and anattā. The convergence was noticed by philosophers in the 20th century and has generated a productive comparative literature.
