On light, darkness, and what the neurodivergent mind finds in the space between.

A shadow is not the absence of light.

This seems obvious until you sit with it. A shadow is the proof of light — its shape, its angle, its intensity all recorded in the darkness it casts. You cannot have a shadow without a source. The darkness is not emptiness. It is information.

I have been watching shadows for as long as I can remember. Not as an interest I developed, but as something that happened before I had the capacity to choose it — a way of seeing that arrived before language and stayed. The way a single lamp throws three different shadows from three different walls. The way shadows at noon are short and dense and certain, and shadows at dusk are long and uncertain and full of blue. The way the shadow of a moving thing tells you the speed and direction of what you can’t directly see.

I wrote a whole book out of this. But the deeper I go into it, the more I think the shadows were never really about light.

They were about everything that gets revealed when you stop looking directly at the thing and start looking at what it leaves behind.

The Neurodivergent Relationship with Darkness

There is a particular way that neurodivergent people tend to relate to their own difficult experiences. Not better or worse than the neurotypical way — different in texture, in how it sits in the body, in what it demands.

We often carry a kind of accumulated darkness that doesn’t get named correctly. Years of being told we are too much or not enough. The long residue of masking — performing a version of yourself that fit the room at the cost of knowing who you actually are. The grief of a late diagnosis, which arrives not just with relief but with the weight of everything that came before it, now recontextualized. The exhaustion of a world that wasn’t designed for the way you work.

This is real darkness. It is not dramatic or self-indulgent to name it that way. And like all darkness, it carries information — about where the light came from, about what it illuminates, about the shape of the thing that cast it.

The question is not how to eliminate it. The question is how to read it.

What Shadow Work Actually Is

Shadow work — the practice of turning toward the parts of yourself you’ve been trained to hide, suppress, or disown — gets talked about in spiritual and therapeutic circles in ways that can feel either vague or overwhelming. Either too abstract to be useful or too excavating to be safe.

I want to offer a simpler frame: shadow work is paying attention to what you do when no one is watching. What you feel when you stop performing. What comes up in the quiet after the mask comes off.

For neurodivergent people, this often means making contact with parts of yourself that were suppressed very early — the stim that got corrected out of you in childhood, the sensitivity that was labeled as overreaction, the way your mind moves that adults kept trying to redirect. These aren’t pathologies waiting to be processed. They’re the original self, still intact underneath the years of accommodation, still carrying the information it was carrying before anyone told you it was wrong.

The shadow isn’t the bad parts of you. It’s the unexamined parts. And unexamined is not the same as bad.

Light Needs Something to Fall On

Here is what I keep returning to: light without surface is invisible.

In a perfect vacuum, a beam of light passes through without revealing itself. You cannot see the beam — only what it strikes. The light needs matter, needs texture, needs something to land on and be altered by, in order to become visible at all.

I think about this in relation to neurodivergent experience. The depth of feeling, the intensity of perception, the way everything lands harder and stays longer — these are not comfortable traits to carry. They make certain surfaces unbearable. They make certain environments impossible. They make rest difficult and recovery long.

But they are also the reason the light is visible at all. The very sensitivity that makes hard things harder is the same sensitivity that makes beauty land the way it does. That makes music do what music does to a nervous system like ours. That makes connection, when it happens, feel like the most important thing in the world.

You cannot separate these. You cannot keep the depth of the good and flatten the depth of the hard. It is one thing, one sensitivity, one surface.

The Practice

I am not going to tell you how to do shadow work in five steps. I don’t think it works that way, and I don’t think I’m the right person to prescribe a process.

What I can tell you is what has worked for me: moving toward the things I avoid thinking about, slowly and without forcing. Noticing what I do when I’m regulated versus what I do when I’m not, and treating both as data rather than evidence of character. Writing toward the difficult things rather than away from them — not to resolve them, but to give them a shape I can look at from the outside.

And watching shadows. Literally. The way they move across a wall as the light changes. The way they hold the record of where the light has been.

There is something about the practice of observing shadows in the physical world that makes the metaphorical version less frightening. As though training the eye on something beautiful and harmless prepares it, slowly, to look at something true.

There Is No Darkness That Does Not Serve the Light

I believe this. Not as comfort or consolation, but as something I have observed repeatedly, in the physical world and in the interior one.

The darkest periods of my life produced the clearest writing. The traits that caused the most friction against the world were the same ones that eventually made a body of work possible. The sensitivity that made me hard to be around, in certain contexts and at certain volumes, is the same sensitivity that makes it possible to write something that lands in someone else’s chest like something remembered.

This is not a silver lining argument. I’m not saying the hard things were worth it, or that suffering has inherent value, or that you should be grateful for what broke you.

I’m saying: look at what your darkness is the shadow of. Look at what had to be shining to cast it. That source is still there. It has always been there.
