At Ranger camp when I was a kid, we had a phrase we said before a hard hike or a long cold night: be prepared, physically, mentally, and spiritually. It's the same shape as the older saying, body, mind, and soul. Three parts. Three things to get ready.

I've carried that phrase for decades, and one part of it has never sat still. Physical is easy to locate (it's the body, the legs, the lungs). Mental is easy too (it's the planning, the deciding, the higher-level thinking). But spiritual? Where does that one actually live? As I've gotten older I keep trying to pin it down, and this post is me doing that out loud.

One thing first, so there's no confusion. I'm a spiritual person. That comes from how I was raised, and I'm not trying to argue anyone out of anything, including myself. That's a separate topic for a separate day. This post is narrower: when people point at the heart, the gut, the soul, a transcendent feeling, and call it spiritual, what is actually happening in the body when they do? I think the honest answer is more tractable, and more moving, than "somewhere in the ether."

Where Spiritual Lands on the Map

Line up the three parts and try to give each one an address.

Physical has an address. It's the nervous system running the body: heartbeat, balance, the ache in your shoulders under a pack. Mental has an address too. It's the deliberate, effortful thinking (weighing options, doing the plan, holding an argument in your head). Both of these you can point to.

Spiritual is the one left holding no clear address. And when a category has no home, it tends to become the bucket for everything the other two can't explain: love that arrives without being decided on, the feeling of being part of something bigger than yourself, awe, grief, a gut conviction you can't argue your way out of. My claim is simple: that bucket isn't empty and it isn't cosmic. It's the social and emotional layer of being human. The feelings we file under spiritual are largely the felt output of systems that are older and faster than deliberate thought, systems we don't consciously author. That's exactly why they feel like they come from somewhere beyond us.

The Body Was the Map All Along

There really are older, faster, largely automatic systems doing this work. The amygdala handles threat and emotional salience (the jolt before you've decided anything). The hypothalamus runs drives and releases oxytocin, the hormone tied to bonding and attachment. The hippocampus, sometimes cast in folk stories as the "emotion center," is actually the memory structure (it gives events their context, which is a different and quieter job). These systems are fast, deep, hard to override, and not consciously chosen. You don't decide to feel the pull toward your family. You don't reason your way into awe. The output arrives fully formed, without a paper trail you can inspect. A feeling with no visible author is exactly the kind of feeling a person reaches for the word "spiritual" to describe.

Darwin gave the cleanest demonstration of this I know of. He put his face right up to the glass in front of a puff adder, determined not to flinch when it struck. It struck, and he jumped back anyway, "my resolution went for nothing," he wrote in The Expression of the Emotions in Man and Animals. Knowing the glass was there changed nothing. An older system overrode the deliberate one before the deliberate one could vote. That gap (the reaction that runs without your permission) is the same gap the word "spiritual" so often names.

Old language for these feelings is almost always anatomical. Heart. Soul. A gut feeling. People said heart-and-soul long before anyone could name a hormone, and they weren't being vague on purpose. A "gut feeling" turns out to point at a real sense for the state of your own insides: interoception, the perception of internal signals like heartbeat, breath, and the state of your stomach. "Heart" works the same way (the pounding chest of fear or love is autonomic arousal you can feel). None of these are wrong. They're folk maps, and the territory they were mapping was the body all along.

What Is the Soul?

Soul is the roomier word, and it deserves more than a footnote. Here's how I've come to think about it: the soul is the collective memory of a full experience. It's the accumulated record of everything you've lived, compressed into the characteristics of who you are. Not your IQ, not your aptitudes (those sit closer to the mental layer), but the deeper thing underneath them. And crucially, it sits at a level where everybody's soul is equal, even though every soul carries different qualities. Aptitude ranks people. Soul, in this sense, does not.

Pixar has been circling this idea from both sides. In Soul, a soul is what has a personality and a "spark" before and after a life, the essence that isn't the body. A few years earlier, in Inside Out, they told the inverse story: the self is not a single narrator but a committee of emotions arguing at a console. One studio, two films, and together they sketch what most spiritual traditions have said for a long time, that there is some essence of a person that transcends the body, and that it is somehow both singular and made of many things at once.

A Soul Made of Parts

That second half (made of many things) is the part modern thinking has gotten sharper about. We tend to assume we are one unified self. The more accurate picture is that we are a coalition. Psychology has a whole model for this: the Internal Family Systems approach treats a person as a set of interacting parts (subpersonalities) rather than one voice. Neuroscience points the same way. Jeff Hawkins's A Thousand Brains argues the cortex is thousands of small, semi-independent models running in parallel, each building its own map, voting, and only sometimes surfacing a single answer to the conscious self. Which is why, in the ordinary flow of a day, things happen in your own head that you can't fully explain. The snake flinch is one vote winning before you knew a vote was being held.

Add time to that and the coalition stretches across your whole life. You are, in a real sense, a different person young than old. Your younger self was always talking to a future self it couldn't see, and your future self spends a lot of energy reconciling with the decisions the past self made. Packaging all of that (the parts, the memories, the accumulated experience across time) into one word, soul, is genuinely easier than tracking every thread. Fiction has been rehearsing what happens if we could capture the whole bundle: Ghost in the Shell and Expelled from Paradise both imagine a "ghost," a full consciousness lifted out of the body into a digital world, cross-cutting memory and feeling and identity. It's the most compelling picture I've seen of what a soul would look like made explicit. And it's no longer only fiction: today's AI agents are often described as ghosts of a kind, personas distilled from the thoughts of millions of people posted across the internet, reflected back as one coherent voice. A composite that reads as singular. That's closer to what we are than we like to admit.

Belonging Is the Thing We Keep Calling Spiritual

Now bring the feelings together, because this is the part I actually wanted to work out. The moments I would most readily call spiritual are moments of love, acceptance, and belonging. Being wanted. Being part of a group. Being part of something bigger than yourself. And when I line those up honestly, that is what most of the spiritual experiences I've had have been about.

I've felt it in church. I've also felt something nearly identical at a concert, and the concert is not a religious thing. It's a gathering thing. A crowd, all turned toward the same thing at the same time, moving together. The venue is different but the feeling rhymes because the mechanism is the same. Sociologists named it a century ago: collective effervescence, the charge a group generates through shared attention and synchrony. Chanting, singing, and moving in time produce measurable synchrony between people and a release of the bonding hormone. Church and concert are two doorways into the same room. What makes it feel spiritual is not the doctrine. It's the belonging.

The strongest version I know of is becoming a father. The first time, something in me changed that I did not choose and could not have talked myself into. That's not just a feeling in the poetic sense. New fathers show real hormonal and structural brain changes tied to caregiving and attachment. The love felt transcendent, beyond words, bigger than me, and it was also my hypothalamus and my chemistry answering an ancient need. Both of those sentences are true at the same time, and holding them together is the whole point. We are, at the end of the day, social animals. The drive to belong is one of the most studied motivations in psychology, a fundamental need on the level of food and safety. When that need is met, being accepted, being part of a bigger whole, the feeling it produces is the one we've been calling spiritual all along.

This is a Renewal move: not solving spirituality, but re-examining where I'd filed it. For me, moving the feelings we call spiritual from "the ether" into the social and emotional systems of the body doesn't cheapen them. It makes them tractable. A yearning for family or belonging is something you can honor, tend, and act on, instead of something that only happens to you. The soul, seen this way, isn't discarded either: it's the collective memory of a full experience, a coalition of parts held together across time, and it shines brightest when it connects to other people. The reframe sits alongside the secular meaning of life (Discovery, Play, Joy) and Faith. Guts. Stamina., where faith is named as the Searching move rather than a metaphysical claim. All three are the same instinct: take the words that feel too big to hold, and find the human system underneath. For the framework that ties these together, see the Quest Engine.
