Buddhism, plainly · Basic ideas · 6 min read

The Buddha said there are three things true of everything you will ever meet — every object, every feeling, every person, including you. They’re called the three marks, and they aren’t rules or beliefs; they’re descriptions, like “water is wet.” You can check them against your own life. Most people find that the first one is obvious, the second is uncomfortable, and the third takes a while — and then quietly changes everything.

1. Everything changes

Look at anything long enough and it’s moving. The cup of tea cools; the mood you woke up with is gone by lunch; the body you had at twenty is not the one reading this. Chinese has a beautiful two-character word for it, 無常 wúcháng — “no constant” — and your family probably says it with a sigh at funerals. But it isn’t only a sad fact. It’s also why grief lifts, why a hard year ends, why the person who hurt you isn’t the same person tomorrow. The rule cuts both ways. Everything you love will change; so will everything you dread.

2. Nothing holds still long enough to satisfy

This is the uncomfortable one. Because everything moves, nothing you can grab will stay the shape you grabbed it in. The promotion becomes the job. The new phone becomes the phone. The person you were desperate to be with becomes the person whose chewing bothers you. This isn’t because life is bad; it’s because you were asking a moving thing to be a resting place. The Buddha’s word for this was the same one he used for the ache in the first noble truth — the wheel that doesn’t quite sit on its axle. Once you see it, it stops being a personal failure. You didn’t pick the wrong job or the wrong partner. You asked the wrong thing of them.

3. There’s no fixed self doing the wanting

Here’s the one that takes a while. Look for the “you” that all this is happening to — the solid, central person behind the eyes. What you actually find, when you look, is a stream: thoughts, feelings, memories, a body, all changing, all arriving and leaving. There’s definitely someone here — you’re reading this — but it’s more like a river than a rock. The river is real. It just isn’t made of any one drop, and it isn’t the same water it was a minute ago.

Why does this matter, practically? Because the harshest voice in most of our heads speaks as if there were a fixed self to defend: I’m the kind of person who, I always, I’ll never be. If the self is a river, none of those sentences can be fully true. You’re not the kind of person who; you’re a person who did, and could do differently. The anxiety that grips the handrail is protecting something that was never as solid as it felt. Loosen that and the grip loosens too.

What to do with three true things

Not much, at first. Just notice them. When the tea cools, notice: changes. When the new thing goes flat, notice: doesn’t hold. When the harsh sentence starts with I always, notice: river, not rock. The tradition says that noticing these three, over and over, in small ordinary moments, is itself the path — that you don’t need to believe them, only to catch them in the act. And every time you do, the grip loosens by a hair, and the wheel turns a little smoother.

The old words, since you’ll meet them

I promised no old words until the end. Here they are, so you recognize them on a temple wall or in a book: the three marks are anicca (impermanence, 無常), dukkha (unsatisfactoriness, 苦), and anattā (non-self, 無我). In Chinese temples you may see a related set of three or four “seals” of the teaching, 三法印 sān fǎ yìn, with the last one being peace — 涅槃寂靜, nirvana is stillness — which is the tradition’s way of saying: and when you see the first three clearly, the fever goes out.
