The Map Is Not the Journey

Why I wrote a book about attention in the language of physics, and the thing I was most afraid of while writing it.

I wrote a book that explains attention using entropy, gravity, mass and time dilation. People assume the physics came first and the practice was fitted to it. It was the other way round. The practice came first, by about ten years, and the physics was the only language I could find that described it without asking anyone to believe anything.

That choice has a cost, and I want to name it, because it is the thing I was most awake to while writing.

Here is what I have watched happen, in more than one tradition, to more than one person I care about. Someone is given an image to help them understand a practice. The image is good. It does its work. And then, somewhere over the following years, the image quietly becomes the thing itself. They can describe the symbol beautifully. They can tell you what it means, where it comes from, which teacher explained it best. What they have stopped doing is the practice the symbol was pointing at.

This is not stupidity, and it is not insincerity. It is that a symbol is easier to hold than a discipline. A symbol can be admired. A discipline has to be done again tomorrow, at the same unglamorous hour, whether or not you feel like it.

So when I reached for physics, I knew exactly which hole I was standing next to. I had found a set of pictures that make a difficult inner process legible, and pictures are precisely the thing that eats practices.

The rule I set myself was this: every image in the book has to end in something you do.

Not something you understand. Something you do. The tortoise pulling into its shell is only worth printing because it ends in thirty seconds of bringing your attention back. The shopping trolley pushed from four sides is only worth printing because it ends with you closing twelve tabs. If an image could not be followed by an instruction, it came out, however good it sounded.

There is a test that comes with this, and I use it on my own writing before anything else:

Can you state the practice without the image?

If you can — if "pull your attention back to your own centre for thirty seconds" survives with no tortoise anywhere near it — the image is a raft. Useful for crossing, not a place to live. If you cannot, if the only way you can say what to do is to retell the story, then the image has eaten the practice and what you have is decoration.

Apply it to my book. Entropy, gravity, mass, time dilation: take all four out, and what is left is a short list of plain instructions about where your attention goes and how often you bring it home. That is the book. The physics is the raft.

I would rather a reader came away with the instructions and forgot every picture I used, than came away able to explain vector dispersion at a dinner party while their Tuesday afternoon carried on exactly as before.

The language of physics is not a claim about the physics of the mind. It never was. It is a map, and a map is worth carrying right up to the moment you mistake it for the ground.
