The Three Marks of Existence: Anicca, Dukkha, Anatta

By Tim Yu · Updated 2026-06-04

The three marks of existence (Pāli tilakkhaṇa) are three truths the Buddha said characterise all conditioned things: impermanence (anicca), unsatisfactoriness (dukkha), and not-self (anattā). Everything that arises from causes is fleeting, cannot finally satisfy, and contains no fixed, independent self. Seeing this clearly — not merely believing it — is the heart of liberating insight.

The short answer

The three marks are the Buddha’s account of what all conditioned things have in common. They are sometimes called the three characteristics, and in Pāli the tilakkhaṇa. The Dhammapada states the triad in three parallel verses (277–279, trans. Acharya Buddharakkhita):

“All conditioned things are impermanent” … “All conditioned things are unsatisfactory” … “All things are not-self” — and in each case, “when one sees this with wisdom, one turns away from suffering. This is the path to purification.”

This is not a gloomy creed but a piece of clear-eyed realism: a description of how things actually are, rather than how we wish them to be. The marks are precisely what insight meditation (vipassanā) trains the mind to see directly, and seeing them is what loosens the craving that, the Four Noble Truths teach, holds suffering in place. (Unfamiliar terms are in the glossary.)

In more depth

Three characteristics of everything conditioned

Look closely at any experience — a sensation, a mood, a relationship, a life — and the Buddha says you will find three features running through all of it. Far from being a pessimist’s complaint, this is offered as a freeing accuracy: most of our suffering comes from expecting conditioned things to be permanent, satisfying, and solidly “ours,” when by their nature they are none of these. Let us take the three in turn, and then see how they lock together.

1. Anicca — impermanence

The first mark is anicca: everything that is put together comes apart. Whatever arises from causes — a thought, a feeling, a body, a star — is in constant change and will eventually pass. Nothing assembled stays assembled. This is the most immediately verifiable of the three: you need only watch your own breath, or your own mind, for a minute to see that experience is a river, never a stone. The trouble is not that things change but that we try to stand on them as though they would not — and so impermanence, met with clinging, becomes the doorway to the second mark. (For the full picture, see our guide to anicca, the truth of impermanence.)

2. Dukkha — unsatisfactoriness

The second mark, dukkha, is often translated “suffering,” but the word is wider than pain. It points to the unsatisfactoriness or unreliability of conditioned things: their built-in inability to deliver the lasting security and contentment we keep demanding of them. Because everything we grasp is impermanent (the first mark), it slips through our fingers, and the grasping itself aches. Ordinary pain is dukkha; so is the subtler ache of watching good things change, and the background unease of a life built on shifting ground. This is not the claim that life is only misery — pleasure is real and worth enjoying — but that no impermanent thing can finally satisfy a mind that clings to it. (We explore this further in why do we suffer?.)

3. Anattā — not-self

The third mark is the deepest and the most distinctive of Buddhism: anattā, not-self. The teaching is that there is no permanent, unchanging, independent self or soul — no fixed essence — within or behind experience. What we call “I” is a flowing process, not a thing that owns the process. The Buddha argued this directly in the Anattalakkhaṇa Sutta (SN 22.59), his discourse on the not-self characteristic. Taking the five aspects that make up a person in turn — body, feeling, perception, mental formations, and consciousness — he points out that each is impermanent and bound up with stress, and not finally under our control, and therefore cannot rightly be taken as a stable, owning self. The conclusion he invites is to regard each, in his words, as: “This is not mine. This is not my self. This is not what I am” (trans. Ṭhānissaro Bhikkhu).

It is vital to hear what this does and does not say. Anattā does not mean you do not exist, and it is not a counsel of despair. It means the person is a dynamic, conditioned process rather than a permanent kernel of selfhood — and that the exhausting project of defending and inflating a fixed “me” is built on a misreading. Letting that misreading go is experienced not as loss but as relief. (This teaching has a full guide of its own — see anattā: the teaching of non-self; and for how a self-less process can still be reborn, see rebirth vs reincarnation and what happens after death.)

The chain that links the three

The marks are not a random list of complaints; they form a chain, and the early discourses spell it out. In the Anattalakkhaṇa Sutta, the Buddha leads his hearers through it step by step: he asks whether each aspect of experience is constant or inconstant — inconstant; whether what is inconstant is easeful or stressful — stressful; and whether it is fitting to regard what is inconstant and stressful, and subject to change, as “This is mine. This is my self. This is what I am” — and the answer is no. In short: what is impermanent (anicca) cannot give lasting ease (dukkha); and what is impermanent and unsatisfactory and beyond our final control cannot be a permanent, owned self (anattā). The three marks are three views of a single fact, and seeing any one of them clearly tends to open onto the others.

A subtle but important point: the conditioned and the unconditioned

There is a precise detail in the Dhammapada verses worth pausing on. The first two verses say that all conditioned things — in Pāli saṅkhārā, things that are put together from causes — are impermanent and unsatisfactory. But the third verse widens the net: it says that all things — dhammā, phenomena of every kind — are not-self. The change of word is deliberate. Impermanence and dukkha belong to the conditioned world of cause and effect. But not-self applies to everything, the conditioned and the unconditioned alike — including nirvana itself. Even liberation is not a hidden, higher Self that one finally attains; it too is “not-self.” This guards the teaching against the natural temptation to let a permanent self slip back in through the back door, dressed up as “the absolute” or “the true Self.” In Buddhism, there is no such smuggling: not-self goes all the way down.

Why the three marks matter: from seeing to freedom

None of this is meant as philosophy for its own sake. The marks matter because seeing them is what frees the mind. It is one thing to agree, intellectually, that things are impermanent; it is another to watch impermanence directly, moment by moment, until the grip of craving simply loosens because it has nothing solid left to cling to. That direct seeing is the work of insight meditation, and the Dhammapada names its fruit plainly: “when one sees this with wisdom, one turns away from suffering. This is the path to purification.” Insight into impermanence weakens our demand that things stay; insight into not-self dissolves the self-centre around which craving organises itself. This is how the three marks connect to the rest of the path: they are the wisdom that undercuts the craving the Four Noble Truths identify as the cause of suffering, and so they open toward its end.

One teaching, held across the traditions

The three marks are not the property of one school; they run through the whole of Buddhism. The Theravāda tradition makes the tilakkhaṇa explicit and organising, the very thing insight practice sets out to see. The Mahāyāna traditions affirm all three and develop the teaching of not-self further still, into the far-reaching doctrine of emptiness (śūnyatā) — that nothing whatsoever possesses an inherent, independent existence of its own. The vocabulary and emphasis differ from tradition to tradition, but the core is shared ground: clinging to permanence and to a fixed self is the root of our suffering, and seeing through that illusion is the way out. On this, the whole of Buddhism speaks with one voice.
