My mystical experience at Bonnaroo upended everything I thought I knew about reality. In those profound hours of expanded consciousness, I glimpsed something that my ordinary mind struggled to comprehend—and still does. When I was one with the Universal Mind, I possessed infinite knowledge and wisdom. But to return to human form, to fit back into the constraints of my individual consciousness, I had to compress, simplify, and approximate. I had to distill the infinite into something a finite brain could hold.

And that’s when I realized the most humbling truth of all: everything I thought I knew—everything anyone has ever claimed to know with certainty—is merely a model, an approximation, a theory. All flawed in some way. None as complete as the whole.

Imagine you and I are lost deep in the woods, miles from civilization, without smartphones or GPS to guide us. Desperate, you ask if I have anything that could help us find our way back. I confidently reply, “Yes, I have a map!” You breathe a sigh of relief as I reach into my backpack and produce… a globe, a small spherical model of Earth.

You stare at it, perplexed. “What are we supposed to do with this?”

“Well, it’s a map of Earth, and we’re on Earth, so it should help, right?”

It’s obvious to you that this globe, while technically a map, is completely impractical for our situation. Navigating out of dense woods with a globe would be nearly impossible.

So you ask again, “Do you have anything else?”

This time, I pull out a topographical map—a detailed flat representation of the terrain, complete with markings for elevation, roads, rivers, and vegetation. Now this seems useful! We identify a nearby mountain range, use the rising sun to orient ourselves, and pinpoint the direction we need to go.

But as we begin our trek, we quickly realize the map, while helpful, isn’t perfect. The green area indicating vegetation turns out to be an impenetrable thicket of thorny bushes. The blue line representing a river is actually a raging torrent, impossible to cross safely. And those gentle contour lines? They reveal themselves as sheer, jagged cliffs blocking our path.

The map, though informative, didn’t fully prepare us for the harsh realities of the terrain.

In my 25 years in the military, I’ve been lost in the wilderness more times than I can count—from the swamps of Alabama to the barren deserts of Iraq to the perilous mountain passes of the Hindu Kush in Afghanistan. And if there’s one thing I’ve learned, it’s that all maps have their limits.

Maps are undoubtedly useful, but even the most meticulously crafted maps are wrong to some degree. They are, by their very nature, simplified representations of reality. They distort certain information to make other details clearer, and they inevitably leave out nuances.

We can create increasingly detailed maps, but as they become more detailed, they also become more unwieldy. Google Maps, perhaps the most detailed comprehensive map of Earth we have today, is estimated to contain around 50 petabytes of data. If you printed it out, the map would cover approximately 46 square miles—larger than 22,000 football fields. Yet despite its staggering detail, Google Maps still has errors and omissions. Like all maps, it’s a snapshot in time that doesn’t account for the ever-changing dynamics of the world.

A truly accurate map would need to be as large as the planet itself and as detailed as reality—but such a map would be completely impractical and defeat the purpose of a map, which is to provide a simplified, manageable representation of the world.

Despite their imperfections, maps remain incredibly useful tools. A globe gives us a general understanding of Earth’s layout. A topographical map offers more specific detail about terrain. And Google Earth provides an even more detailed view of the landscape. But in the end, all maps are just models—approximations of our physical world.

Theories function in much the same way as maps. Just as a map is a simplified representation of Earth, a theory is a simplified model of some aspect of the universe. The universe is infinitely complex, far beyond our full comprehension, so we create theories—mental models that help us understand, explain, and predict phenomena.

These theories include everything from the scientific laws we hold dear, to the religious beliefs that guide billions of people, to the everyday assumptions we make about how the world works. Some of these theories may seem irrefutable, foundational to the universe. But I hate to break the news to you: like maps, they are all flawed in some way. They are incredibly useful, often necessary for us to get through our daily lives, but they are not perfect representations of reality.

Consider the law of gravity. We think of it as an unchangeable truth, a fundamental aspect of our universe. Yet Newton’s law of gravitation is actually a theory—a model we’ve created to explain the behavior of objects in our universe. It’s an incredibly useful theory that has allowed us to accomplish incredible feats, like building skyscrapers and exploring space. But it’s not a flawless representation of reality.

Quantum mechanics, black holes, high-energy systems, extreme gravitational fields, the early phase of our universe after the Big Bang—these are all fields of physics where traditional laws of gravity break down. In these extreme cases, scientists have developed new theories, such as general relativity and quantum gravity, to account for phenomena that traditional gravity cannot explain.

Gravity is a simplified model of something far more complex that humans will never be able to fully explain.

But theories aren’t confined to the realm of science.

The concept of family, for instance, is also a theory—a mental construct we use to understand certain human relationships. What constitutes a family varies widely across cultures and throughout history. I was adopted as a toddler, and today I have connections with both my adoptive and biological families. My understanding of family is expansive: I have adoptive parents, biological parents, godparents, adopted siblings, biological siblings, step-siblings, and a mix of relationships that defy traditional categories. When friends talk about the importance of family, I often smile because my experience of family is so varied and complex. My concept of family diverges significantly from conventional concepts.

Religion, too, consists of theories about the nature of existence, morality, and our place in the cosmos. These theories offer frameworks for addressing life’s big questions and guiding behavior within complex social environments.

Even language is a theoretical framework. The very words you’re reading right now are part of a system of symbols and rules we’ve collectively agreed upon to convey meaning. Similarly, concepts like society, democracy, and individual identity are all theoretical constructs—mental models that help us make sense of our intricate social world.

And what about mathematics? Often considered the purest and most certain form of knowledge. Numbers, equations, geometric shapes—these are abstract concepts we’ve developed to model and manipulate quantities and relationships in the world around us. While incredibly powerful, mathematics is not reality itself, but rather a language we use to describe and predict aspects of reality.

The history of numbers itself illustrates how our theoretical constructs evolve over time. The concept of zero, now fundamental to our number system, didn’t emerge until about 628 A.D. when it began appearing in Indian texts. Similarly, the concept of negative numbers was once considered absurd and impractical. It wasn’t until the Chinese Han dynasty (202 BC – AD 220) that we began to add and subtract negative numbers. Even more recently, in the 15th century, mathematicians introduced imaginary numbers, with the imaginary unit ‘i’ defined as the square root of -1.

It was René Descartes who, in the 16th century, coined the term “imaginary” when describing these negative square roots. While he is most often remembered for his first principle in philosophy—”Cogito, ergo sum,” or “I think, therefore I am”—it is perhaps his contribution to imaginary number theory that has most shaped our understanding of the universe.

Even time itself, that seemingly inescapable flow from past to future, is a theoretical construct. As we will explore later, our everyday understanding of time as a linear progression is an illusion—a useful model our minds create to navigate our experiences, but not an accurate representation of the true nature of reality.

So why do we create these theories? The answer lies in the incredible complexity of the universe we inhabit. Reality, in its fullest sense, is infinitely complex—far beyond the capacity of our small brains to fully comprehend.

Our brains, remarkable as they are, are limited in their processing power. We simply cannot take in and make sense of all the information available to us at any given moment. Theories are our mind’s way of simplifying this overwhelming complexity into manageable chunks. They are mental shortcuts, simplified models that allow us to navigate the world without being paralyzed by its complexity.

When we see an object fall, we don’t need to calculate all the forces acting upon it—our internalized theory of gravity allows us to predict its path and react accordingly. When we interact with others, we don’t need to reassess the nature of human relationships from first principles every time.

These theoretical frameworks are incredibly useful. They allow us to make predictions about what will happen in various situations. However, the very usefulness of these theories can sometimes lead us astray. Because they work so well in many situations, we can fall into the trap of mistaking our theories for absolute truth. We may forget that they are simplified models, not perfect representations of reality.

The key, then, is not to seek theories that are universally and eternally true—such theories are beyond our reach as finite beings in an infinite universe. Instead, the measure of a good theory is its usefulness. How well does it help us predict and navigate the world around us? How effectively does it help us achieve our goals and improve our lives?

The bottom line is that there are no universal, unchanging truths. I’m sorry to my Christian friends, my Republican family, my Dad, and other fundamentalists who believe their way is the one and only way. The best we can hope for is to develop theories that are increasingly useful, that help us make better sense of our world and make more accurate predictions about what will happen in various situations.

However, this view doesn’t mean we should abandon our current theories or treat all ideas as equally valid. Some theories are demonstrably more useful than others in helping us navigate reality.

Which brings us to the theory presented in this book—the concept of the Universal Mind, the philosophical framework that guides my faith and teachings at Heartspace Church. I don’t claim that this is the ultimate theory or the final word. Like all theories, it is a model, a way of looking at the world that may or may not resonate with your experience.

What I offer is a framework for understanding consciousness, identity, and our place in the universe. It’s a theory that challenges many of our common assumptions about the nature of reality, but one that I believe can be profoundly useful in navigating life’s challenges and finding deeper meaning and fulfillment.
