What is anicca (impermanence)?

Anicca is the Pali word for impermanence (anitya in Sanskrit). It is the teaching that everything which arises from causes will change and, in time, pass away. It is the first of the three marks of existence, alongside dukkha and anatta.

Everything conditioned changes

The Buddha taught that bodies, feelings, perceptions, thoughts and consciousness are all impermanent. So are houses, mountains, friendships and reputations. Some things change quickly, like a mood. Others change slowly, like a coastline. But nothing that depends on conditions stays the same for ever.

This is easy to agree with as an idea. The teaching asks for more than agreement. It asks us to see impermanence directly, in our own experience, moment by moment.

Why it matters

Impermanence is not a problem in itself. The difficulty comes from clinging. When we treat changing things as if they were lasting, we are bound to be disappointed. In the early texts the Buddha often asks his listeners a series of questions: is the body permanent or impermanent? Impermanent. Is what is impermanent satisfying or unsatisfying? Unsatisfying. Is it fit to be regarded as “mine” or “my self”? No. This is how impermanence leads on to the other two marks.

According to the traditional accounts, the Buddha’s last words to his followers were a reminder that all conditioned things are subject to decay, and that they should strive on with diligence.

Impermanence in meditation

In insight meditation, called vipassanā, practitioners watch sensations, sounds and thoughts appear and disappear. Over time, the changing nature of experience becomes obvious rather than theoretical. Many people find that this brings a lightness: if a painful feeling is impermanent, it does not need to be feared so much.

A balanced view

Impermanence is not meant to make life seem bleak. It is also why growth and change for the better are possible. A habit of anger can fade. Kindness can be developed. Because things change, the path to the end of suffering is possible at all.

You can reflect on impermanence in simple ways: watching the breath come and go, noticing a sound fade, or remembering that this day will not come again. Such reflections can make ordinary moments more vivid and relationships more precious.
