Why The Normal Map
Move the light.
The surface is flat. Turn the light a little, and ridges appear. Turn it again and different parts catch the brightness. It looks like there’s something you could run your fingers over.
Open the demonstration on its own, or continue with the explanation below.
Now look from the side.
Still flat.
In computer graphics, a normal map supplies information about the directions a surface appears to face. The renderer uses that information to calculate light and shade. It can make a simple surface look detailed without adding all that detail to its geometry. “Normal” means perpendicular here. It’s a direction, not a standard you have to live up to. Technical explanation from Khronos.
That distinction is part of why this name felt right for the collection you’re reading.
From here, from there
Some of the most powerful moments I’ve found have happened on stage. Improv comedy. Acting. Riffing with friends in a corner of a room. A conversation where we start taking apart what happened and why, and discover that we weren’t all living the same account of it.
In improv, you offer something and someone receives it. What they do with it becomes part of what happens next. You can arrive with an idea, but the exchange has somewhere else to go. The room contributes too. Sometimes the connection is what makes the moment work.
I think about that when I say:
“I know that my perspective reality exists, and others have told me how my existence has affected their reality”
I experience from here. Someone else tells me what it was like from there. Their account may bring something into view that I hadn’t noticed. We can be in the same conversation and come away with different memories of what mattered.
There’s research that gives us another way to look at that exchange. Greg Stephens, Lauren Silbert, and Uri Hasson studied a storyteller and people listening to a recording of her story. Patterns of brain activity were related across the speaker and listeners, and the coupling was associated with comprehension. It wasn’t an improv experiment. But it gives us a concrete reason to investigate what communication makes possible between people.1
“You came back.”
The words stay the same. Read them in each context below. These are invented illustrations, not scenes from my marriage or a record of a performance.
A reunion: Someone returns after a long time away. The speaker has been waiting by the door.
A practical follow-up: A colleague returns to pick up a forgotten bag. The speaker looks up from their desk.
A difficult conversation: Someone returns after leaving an unfinished disagreement. The speaker hasn’t yet heard why they left.
What did you hear in the line? What else would you need to know? These examples give context to words. They don’t tell you what you must feel.
Connection has stakes
I recognize another part of this in the changes in my marriage. Anxious attachment became something I needed to understand. I’ve been learning through Hold Me Tight and Emotionally Focused Family Therapy (EFFT). Those ideas belong beside the performance stories because connection has stakes outside a room full of laughter.2
EFFT grew from Emotionally Focused Therapy (EFT), developed primarily by Dr. Sue Johnson, a Canadian clinical psychologist and researcher. Dr. James L. Furrow has been a major developer of its family application. With Gail Palmer, Johnson, George Faller, and Lisa Palmer-Olsen, he authored Emotionally Focused Family Therapy: Restoring Connection and Promoting Resilience. The attachment-based approach brings attention to the emotional bonds within a family.3
James Coan and colleagues studied how holding a spouse’s hand could change neural responses to threat. Later, Johnson, Coan, and their collaborators examined those responses before and after Emotionally Focused Therapy for couples. Their findings suggested changes in how participants responded to threat in a partner’s presence. The follow-up was a small study without a separate control group, so it leaves questions open. These were couple-focused studies, distinct from EFFT’s family application. They give me a research connection to consider alongside my own experience.4,5
Communication: Stephens, Silbert, and Hasson’s 2010 study used recorded storytelling. Coupling was associated with comprehension. Its connection to improv here is my interpretation; it doesn’t establish shared thoughts or telepathy.1
Attachment: Coan, Schaefer, and Davidson’s 2006 experiment involved 16 married women facing the possibility of an electric shock. Spousal handholding reduced some threat-related neural responses.4
Couple therapy: The 2013 follow-up analyzed 23 couples, with women undergoing scans before and after EFT. It had no separate untreated control group. It wasn’t a trial of EFFT or the Hold Me Tight book. These are empirical findings; the proposed mechanisms remain emerging evidence.5
Move the light again
The comparison has a limit. A person is much more than a shaded surface, and a relationship can change through what we do together. But the demonstration gives us a starting question: what am I seeing, and what contributes to the way it appears?
Donald Hoffman takes that question into perception. His interface theory proposes that what we perceive guides our actions without necessarily showing the underlying structure of reality. His further proposal that consciousness is fundamental is something we can explore as theory. I don’t need to settle it before I can listen to another person’s account of our encounter.6,7
This is where The Normal Map begins for me. With an experience, and the attempt to understand it. With a framework that helps something become visible, then a conversation that changes the framework.
Later in the book, we’ll open what I call 4D and 5D portals. We’ll look at emotional patterns, memory, the felt space of relationship, and questions about essence and connection that exceed a simple physical description. These names carry an experiential and theoretical framework. The graphics demonstration doesn’t prove additional dimensions or give us a picture of the soul. It lets us practice distinguishing an appearance from our explanation of it.
A pause before the doors ahead
You can explore all of this through movement, stillness, and breath. Move the light or change your position if that’s comfortable. Pause long enough to notice what you can describe. Let your breathing remain comfortable while a question stays open. If you feel nothing unusual, that’s an account too. No special posture or breath technique is needed; you can skip the interaction and keep reading.
| Door | An invitation |
|---|---|
| 3D: What I can encounter | Begin with the body and the world you can act in. |
| 4D: What shapes the encounter | Explore patterns, emotion, and the meaning an experience takes on. |
| 5D: What the encounter opens | Sit with questions of essence, connection, and unity. |
These doors introduce the book’s vocabulary. They’re invitations to inquiry, not measurements of a consciousness level.
For now, look at the surface once more.
What changed when you moved the light?
