The Honest Answer to “What Does Meditation Do for You?”
The strange Zen paradox behind zazen and its unexpected side effects.
This essay follows a recent SHIBUMIWORKS PROJECT dialogue about zazen and sleep.

Why Zazen “Doesn’t Work” — And Why That’s Exactly the Point
People ask me this more often than I expect.
Usually it comes after they’ve read one of the SHIBUMIWORKS dialogues, or after a conversation at a bar somewhere in Osaka where the topic drifted — as it does — toward sleep, stress, and the general difficulty of quieting a mind that never really stops. The question arrives with a kind of hopefulness underneath it. They’ve heard something. They want to know if it’s real.
And I always pause before I answer, because the honest answer is a strange one.
The honest answer is: I don’t know. And I’m not sure the question is quite right.

Let me try to explain what I mean by that.
When people ask what meditation does, they’re usually imagining something like a supplement. You take it, you wait, something improves. Sleep quality, focus, stress levels, whatever the target is. And to be fair, there’s real research suggesting that regular sitting practice has measurable physiological effects — slower breath, reduced cortisol, lower resting heart rate. Bodies respond. That part is not myth.
But zazen — the sitting practice rooted in Zen — was never designed with those outcomes in mind. It predates the concept of self-optimization by about a thousand years. The instruction passed down through the tradition is almost absurdly simple: just sit. Not “sit and focus on your breath.” Not “sit and visualize calm.” Just sit, with your spine upright and your hands in your lap, and let whatever happens happen.
Shikantaza — 只管打坐. Just this.
The problem — and this is the thing I find genuinely difficult to communicate — is that the instruction sounds passive, but it’s one of the hardest things I’ve ever tried to do consistently. Because the moment I sit down, some part of my mind immediately wants to audit the experience. Is this working? Am I doing it right? I should be more relaxed by now. That internal checking is not meditation. It’s just anxiety wearing meditation’s clothes.
Here is what I’ve actually noticed, over years of sitting — and I want to be careful here, because I’m only speaking from my own experience, not making claims for anyone else.
When I stop trying to get something out of zazen, things happen on their own. My breathing deepens without me deciding to breathe deeply. Tension I didn’t know was there — in my jaw, in my shoulders, in the muscles around my eyes — releases slowly, the way a fist unclenches when you stop thinking about it. The thoughts that felt urgent an hour ago become slightly less insistent. Not gone. Just quieter, like a radio in the next room.
And yes — I sleep better on nights when I sit than on nights when I don’t. But I didn’t sit in order to sleep better. That’s the part that’s hard to convey without sounding like I’m playing word games.
The sleep improvement is a side effect. And side effects, by definition, are what happen when you’re not aiming at them.
There’s something in Japanese called mushin — 無心, literally “no mind,” though that translation flattens it considerably. It doesn’t mean absence of thought. It means a state where thought moves without grabbing onto anything, without getting snagged on its own momentum. Martial artists talk about it. So do master craftspeople. You don’t achieve mushin by chasing it. You achieve it by doing the thing in front of you so completely that there’s no room left for the part of your mind that narrates and evaluates.
Sitting in zazen doesn’t produce mushin. But it might — very slowly, over time — make that quality slightly more available to you in ordinary life. The way practicing scales on a piano doesn’t make you a musician, but it changes what your hands can do without thinking.

So when someone asks me, “What does meditation do for you?” — I understand what they’re asking, and I don’t want to be evasive about it. But the most accurate thing I can say is this:
It does nothing that you can aim at. And precisely because of that, it sometimes does everything you needed.
I realize that answer might be unsatisfying. If you came here looking for a list of benefits — eight minutes a day, improved focus, better REM sleep — there are plenty of apps and articles that will give you that. I can’t tell you they’re wrong. Bodies do respond to sitting still and breathing.
But if you’re curious about zazen specifically, the Zen tradition asks something different of you. It asks you to sit down, let go of the question of whether it’s working, and stay there anyway.
What happens after that is between you and the cushion.
If you found peace in these words, feel free to follow for more reflections on Zen and philosophy. Let’s walk this path together.
