This Is the Door by Darcey Steinke The Body, Pain, and Faith
What's it about?
This Is the Door (2025) is an exploration of physical pain and what it reveals about the human condition. Drawing on personal experience, neuroscience, philosophy, and spiritual tradition, it examines how suffering reshapes identity, empathy, and the way we move through the world. It argues that pain – however unwanted – can open us to a deeper understanding of our own bodies, our connections to others, and the fragility and wonder of being alive.
Pain is one of the most universal human experiences, and one of the least understood. It lives in the body but reaches far beyond it, touching memory, identity, fear, and even faith. Yet most of us face it alone, without the language or framework to make sense of what it’s doing to us. But This Is the Door isn’t a book about eliminating pain.
It’s about what pain can reveal. Drawing on the lives of philosophers, artists, saints, and ordinary people in moments of suffering, Darcey Steinke explores how pain can strip away familiar certainties and force us into a deeper encounter with ourselves. Again and again, she finds that suffering, however unwanted, can sharpen our attention to the world, deepen our connection to others, and open unexpected pathways to meaning. In this lesson, you’ll explore pain from the inside out – through the author’s own experience of a debilitating spinal injury, and through the science, philosophy, and spiritual traditions humans have used to reckon with suffering across centuries.
You’ll discover how pain works physically, tracing the nerve pathways and brain networks that make it so consuming and so personal. You’ll explore its mental and emotional dimensions: how it reshapes identity, isolates, and changes the way we relate to our surroundings. And you’ll sit with its spiritual weight – what pain might mean, what it opens up, and why so many traditions have insisted it matters.
Your spine started aging before you were old enough to notice. Deterioration begins by 23 – and by 60, most people will have experienced back pain at least once. It’s one of the oldest taxes the body pays for being human. To understand why, you have to go back much further than you might expect.
Our earliest ancestors weren’t even vertebrates. Ancient predatory fish, some stretching seven feet long with heads the size of basketballs, drove smaller creatures out of the water and onto land. Over millions of years, those creatures adapted to their new environment. Wrists evolved to push bodies up from muddy banks. Spinal discs developed to bear weight against gravity. The spine we carry today is the long, improbable product of that transition – an evolutionary solution that made life on land possible, but never quite perfected it.
The spine is what philosopher Thomas Moynihan called a ledger of traumatisms – a record of everything evolution cost us. When we moved from four legs to two, the lumbar region took on a load it was never quite designed to hold. Some theorists argue we made that shift so our hands would be free to gather food and fight. Others propose something more romantic: that early humans stood upright to bring their heads closer to the stars. Whatever the reason, philosopher Immanuel Kant believed our dominance as a species came directly from that upright posture – which means our ascendancy and our susceptibility to back pain arrived together. The nineteenth-century Italian poet Giacomo Leopardi knew this intimately.
Born with scoliosis, he spent his life in anguish, hunched over a desk, his body a constant argument against the position he was forced to hold. Pain turned his gaze upward – to the stars above his childhood home, which he wrote about with a longing that was as physical as it was spiritual. They consoled him. They offered company in a suffering that felt otherwise unreachable by language. Pain resists language almost by design. When a body is injured, nerve fibers signal to cells in the spine, which pass the message upward to the brain – not to a single pain center, as scientists once believed, but to multiple regions at once, including those involved in emotion, memory, and decision-making.
Pain’s never just sensation. It’s also everything you remember, everything you fear, and everything you imagine might come next. The author discovered this firsthand when a spinal disc herniated, pressing on the nerve root and sending pain cascading down her hip and leg. Time seemed to stop. She could neither accept the pain nor escape it. She describes feeling like a marionette with a severed cord – the lower half of her body dangling, disconnected, from the rest.
Swimming became her one refuge, returning her body to the element it had evolved from. On land, she was an improvised creature, bound to gravity and carrying the evolutionary cost of standing upright. In the water, briefly, she was free. Her suffering revealed something easy to forget: the spine that made us human was never a perfect design. It's a compromise – one that gave us the ability to stand tall, but also ensured we'd feel the cost of doing so.
While the spine holds us upright, the knees keep us moving. And when they fail, something more than mobility is lost. Knee pain affects a quarter of all adults in the United States, and nearly a million knee replacement surgeries are performed each year. It’s one of the most common forms of chronic pain – and one of the most intimate, because it tends to arrive not in a dramatic moment but gradually, through the accumulated weight of an ordinary life.
A spouse wincing every time he stands. A face draining of color on the stairs. Pain that’s sporadic enough to be ignored for years, until it can’t be. The knee is the body’s largest and most precarious hinge. Discovering everything that can go wrong with it – cartilage fragments floating in synovial fluid, tendons inflamed by jumping, bursae swollen from kneeling on hard floors – makes you understand how improbable the whole arrangement is. Online forums for knee-pain sufferers read like dispatches from people who’ve fallen through a trapdoor in everyday life.
One person was walking up stairs carrying a bucket of ice. Another knelt by the tub to wash her hair. The injury arrived in a moment of complete mundanity. But the life that followed was anything but ordinary. The knee also carries a symbolic weight the spine doesn’t. Across cultures and centuries, falling to one’s knees signals surrender, supplication, or extremity.
Pope Benedict XVI wrote that the devil, in one Desert Fathers story, had no knees. Without them, he couldn’t connect with the earth or reach toward the divine. The most fragile of human joints is also the one most associated with the threshold between body and spirit. At the Marian shrine at Fátima, pilgrims crawl on their knees along a long marble walkway until they bleed, reporting a strange interior expansion as they go. In 1990, 60 disability rights activists abandoned their wheelchairs and crawled on hands and knees up the 83 steps of the US Capitol to demand the passage of the Americans with Disabilities Act. Their bodies, brought low, became the argument.
An eight-year-old girl, asked by a reporter whether she’d make it to the top, replied with certainty that she would, even if it took all night. What kneeling seems to do – whether in prayer, in protest, or in the aftermath of an accident on a rainy road – is return the body to its most honest position. It brings us close to the earth, stripped of the verticality that usually separates us from our own fragility. One woman, waiting for an ambulance after a car crash had shattered her knee, felt the cool rain on her face and something she could only describe as a collective presence gathering around her – not a singular God, but something more like the accumulated kindness of everyone who’d ever lived and suffered and left. Her years of Catholic school hadn’t given her anything as real. It took her broken knee, and the ground beneath it, to get there.
Her experience revealed something easy to overlook: the moments that bring us closest to our fragility can also bring us closest to one another. Pain may force us to our knees, but in doing so, it reminds us that vulnerability isn't an exception to the human experience. It's one of the things we all share.
Pain doesn’t only arrive from outside. Sometimes the brain, pushed beyond what it can bear, generates its own – and in doing so, reveals something about the depths of human suffering that no external wound quite can. Migraines are ancient. An Egyptian medical papyrus from 1550 BCE describes them as “half-headaches” and recommends anointing the head with the skull of a catfish cooked in cumin.
A thirteenth-century monk prescribed shallow cuts to the shins to release dark humors. The cures have since evolved, but the suffering hasn’t. A migraine typically begins with a visual disturbance – a bright empty spot, a geometric shimmer at the edge of vision. Then comes the pain, nausea, and retreat into darkness. Neurologist Oliver Sacks argued that migraines evolved as a protective mechanism, a kind of controlled shutdown for a nervous system pushed beyond its limits. They were, he suggested, a small death to prevent a larger one.
The triggers are as strange as the condition itself: humidity, the full moon, the glare off a car’s chrome bumper, a button fixed to the wrong buttonhole. . . One sufferer feels an ominous drowsiness before each attack. Another knows a migraine’s coming if she feels too happy the day before. Few people have written more searchingly about pain’s relationship to meaning than Friedrich Nietzsche, whose migraines were so severe he sometimes spent days at a time in a darkened room, vomiting blood, unable to tolerate light.
He wore smoked-glass spectacles and carried a parasol on bright days. He submitted to leeches attached to his earlobes and face. And yet from inside this suffering, he produced some of philosophy’s most enduring ideas about what pain might be for – not a punishment, not a failure, but a threshold. The deeper the descent, he believed, the greater the transformation. Nietzsche’s migraines also shaped his relationship to faith. Raised by a Lutheran minister father who died in apparent madness when Nietzsche was five, he eventually declared God dead – in part because his own suffering made divine order impossible to believe in.
Yet his atheism was never cold. Pain hadn’t destroyed the spiritual impulse. It had relocated it, from doctrine to the body itself. Many migraine sufferers describe something similar. The aura – the visual light show that precedes some attacks – has been interpreted across centuries as a conduit to the divine. The Catholic mystic Hildegard of Bingen recorded visions of glowing tendrils and whirling circles that bear a resemblance to what neurologists now call scintillating scotomas.
The boundary between neurological events and spiritual experience isn’t always where we expect it to be. What the brain does in extremity – whether it breaks into light, retreats into darkness, or reaches for meaning it can’t quite grasp – says something about the depth of its need. Pain isn’t just something that happens to the body. It’s something the body does, and the brain is where it does its most extraordinary work.
Skin is the body’s first frontier: the boundary between self and world, between inside and outside, between the living and everything that might harm them. It’s also, of all the body’s organs, the one most legible to others. The history of medicine arguably begins with skin. Long before doctors could peer inside the body, the surface was all they had to work with.
Ancient Egyptian medical texts prescribed remedies for skin conditions using onions, honey, beer, and chopped bat applied as a poultice. An eighteenth-century treatise on skin diseases catalogued everything from common rashes to cases in which pregnant women believed their babies had been physically transformed by whatever touched their skin. The body, these accounts suggest, was never sealed off from the world; it was always porous, always responsive. That permeability runs deeper than folklore. As the body’s largest organ, skin is continuously regenerating – shedding more than a million cells every hour, replacing the entire outer layer every three weeks. Beneath the dead surface lies a living architecture of collagen, elastic fibers, sweat glands, hair follicles, and nerve endings so sophisticated they can communicate complex emotions through touch alone.
One study found that a blindfolded person could identify gratitude, fear, or love conveyed only through another person’s fingers on their arm. Touch was humanity’s first language, older than any kind of verbal expression. And yet skin is also where suffering becomes visible in ways the sufferer can’t control. Sores, rashes, lesions – these don’t just cause pain. They expose it, inviting judgment, revulsion, and exclusion. To live with a visible skin condition is to have your vulnerability written on the outside of your body.
Skin is also where the body announces its own ending. Watching a parent’s skin thin and spot and stretch over a swelling belly is to read, slowly and against your will, a story you can’t stop. Scars carry their own histories – a small mark above a brother’s eyebrow connecting the present to a moment of childhood carelessness. The body keeps records, written on the surface for those who know how to look. What skin makes clear, above all, is that we’re permeable creatures. The world gets in.
Pain gets in. Love gets in. The boundary we imagine between self and everything else is far thinner than we think – and in that thinness lies both our greatest vulnerability and our deepest capacity for connection.
Heartbreak has a body. It lives in the chest, the stomach, the unsteady legs of someone who can no longer walk in a straight line. It wakes you at 3:00 a. m.
and follows you across town toward an apartment where no one’s waiting. Neuroscience now confirms it’s processed by the same neural pathways as physical injury. The brain doesn’t distinguish between a broken bone and a broken bond. For centuries, physicians treated heartache as a genuine medical condition. A seventeenth-century French doctor catalogued its symptoms – fever, palpitations, pallor, a complexion that progressed from white to yellow to a tawny green – and prescribed cooling foods, anti-love elixirs, and special mattress fillings to bring the body back into balance. The treatments might sound absurd now, but the underlying instinct wasn’t wrong.
Something real is happening in the body of a person whose love has ended. What happens, researchers now believe, is this: the brain’s attachment systems – the ones that bond mother to infant, lover to lover – share the same neural architecture. When a relationship ends, the brain registers not only the current loss but something older and deeper. The earliest bond feels retroactively unstable. You’re not only loverless. You’re briefly, terrifyingly, motherless.
That’s why heartbreak produces obsession. The compulsive walks past a former lover’s building, the late-night messages sent and regretted. Rather than weakness, these behaviors are the attachment system doing what it was built to do: searching for what it’s lost. One researcher has drawn direct parallels between the neurology of heartbreak and addiction. The withdrawal is real. The craving is real.
Some therapists now treat severe heartbreak with a combination of beta-blockers and memory reconsolidation exercises, with studies showing significant reductions in suffering after six weeks. But most people don’t have access to that kind of treatment. They muddle through – talking to friends, taking long walks, lying awake in rooms where familiar objects look suddenly strange and transparent. The person who once made the world feel solid has gone, and for a while, nothing quite holds its shape. What heartbreak does, in its worst moments, is hollow you out. And in that hollowness, something unexpected sometimes appears.
Sufferers describe a heightened sensitivity to the world where the senses sharpen and colors deepen. A moon casting reflections on a river at night becomes almost unbearably beautiful. Stars glimpsed from a darkened bedroom feel like messages from somewhere else. The pain of love’s loss and a sudden awareness of something beyond the self turn out, for many, to arrive at exactly the same moment.
The psychologist James Hillman has argued that the heart’s better understood through the metaphor of a lion than a pump. He’s saying it’s not a mechanical organ or a sentimental symbol, but an animal thing – alert and alive to the immediate world, in rhythm with what surrounds it. Heartbreak, at its most shattering, may force a return to exactly that: a raw animal attentiveness that was always there beneath the noise of ordinary life.
Healing isn’t a solitary activity. It happens in the presence of others, in the simple act of being seen in your pain. Frida Kahlo spent much of her adult life in that search. After her final spinal surgery, as the worst of the pain began to lift, she described feeling suddenly kinetic – as if she’d passed from passivity into force.
But the recovery didn’t hold. Her spine became infected. She returned to bed, to the steel corset, to small bottles of liquor tucked into her clothing. What she never gave up was painting. Suffering became her subject, the canvas her means of making it legible. Decades after her death, her image turns up on murals, stickers, and the walls of small shops across the world.
People in pain recognize something in her. She didn’t transcend her suffering. She bore witness to it – and that, it turns out, is its own form of healing. The places humans have built for healing tend to gather around water. The Temple of Asclepius at Epidaurus, established in the fourth century BCE, was built around a spring. Patients bathed, dressed in white robes, and lay down to sleep, hoping the god of medicine might visit their dreams.
In the morning, they spoke with temple staff about what they’d seen and were encouraged to share their ailments with one another. And in the town of Lourdes, where a teenager named Bernadette uncovered a spring in a garbage dump in 1858 after a series of visions, millions of pilgrims still arrive each year to cup the water in their hands and bring it to their faces and lips. Most don’t get a clinical miracle, but they leave with an experience ordinary life rarely allows. The body registers that it’s not alone. And that knowledge, fragile as it is, can be enough. The surgeon who removed the herniated disc that had been defining the author’s life described the moment the fragment came free from the nerve.
What had been chaos settled back to normal. He’d prepared by rehearsing the procedure in his mind three times before dawn. He always wore the same color gloves. Before the operation, he told his patient he’d treat her body as if it were his own. Ritual, presence, attention – in the best medicine, these aren’t incidental. Healing rarely arrives as resolution.
More often, it’s a shift: a softening, a return to something that was always present beneath the pain. Kahlo painted herself across every stage of suffering and survival. She made it mean something. In a world full of people who are hurting and largely alone in it, that remains one of the most generous things a person can do. In this lesson to This Is the Door by Darcey Steinke, you’ve learned that pain isn’t only a physical event.
It’s a total human experience that moves through the spine, knees, brain, skin, and heart – reshaping identity, testing faith, and opening unexpected pathways to connection and meaning. You’ve seen how the body carries the cost of evolution in its very architecture, how the brain generates its own suffering and reaches, in extremity, toward something beyond itself. You’ve explored how skin exposes vulnerability and how touch remains our most ancient form of communication. You’ve understood heartbreak as a genuine physical condition, and healing not as a cure but as the experience of being seen in pain.
By finding ways to bear witness to your own pain (and to the pain of others) you might find that suffering, for all its cost, leaves something behind: a deeper attentiveness, a harder-won empathy, and a closer relationship with being alive.

Drawing on personal experience, neuroscience, philosophy, and spiritual tradition, it examines how suffering reshapes identity, empathy, and the way we move through the world.

Our earliest ancestors weren’t even vertebrates. Ancient predatory fish, some stretching seven feet long with heads the size of basketballs, drove smaller creatures out of the water and onto land.

After her final spinal surgery, as the worst of the pain began to lift, she described feeling suddenly kinetic – as if she’d passed from passivity into force.
But the recovery didn’t hold. Her spine became infected. She returned to bed, to the steel corset, to small bottles of liquor tucked into her clothing. What she never gave up was painting. Suffering became her subject, the canvas her means of making it legible. Decades after her death, her image turns up on murals, stickers, and the walls of small shops across the world.
People in pain recognize something in her. She didn’t transcend her suffering. She bore witness to it – and that, it turns out, is its own form of healing. The places humans have built for healing tend to gather around water. The Temple of Asclepius at Epidaurus, established in the fourth century BCE, was built around a spring. Patients bathed, dressed in white robes, and lay down to sleep, hoping the god of medicine might visit their dreams.
In the morning, they spoke with temple staff about what they’d seen and were encouraged to share their ailments with one another. And in the town of Lourdes, where a teenager named Bernadette uncovered a spring in a garbage dump in 1858 after a series of visions, millions of pilgrims still arrive each year to cup the water in their hands and bring it to their faces and lips. Most don’t get a clinical miracle, but they leave with an experience ordinary life rarely allows. The body registers that it’s not alone. And that knowledge, fragile as it is, can be enough. The surgeon who removed the herniated disc that had been defining the author’s life described the moment the fragment came free from the nerve.
What had been chaos settled back to normal. He’d prepared by rehearsing the procedure in his mind three times before dawn. He always wore the same color gloves. Before the operation, he told his patient he’d treat her body as if it were his own. Ritual, presence, attention – in the best medicine, these aren’t incidental. Healing rarely arrives as resolution.
More often, it’s a shift: a softening, a return to something that was always present beneath the pain. Kahlo painted herself across every stage of suffering and survival. She made it mean something. In a world full of people who are hurting and largely alone in it, that remains one of the most generous things a person can do. In this lesson to This Is the Door by Darcey Steinke, you’ve learned that pain isn’t only a physical event.
It’s a total human experience that moves through the spine, knees, brain, skin, and heart – reshaping identity, testing faith, and opening unexpected pathways to connection and meaning. You’ve seen how the body carries the cost of evolution in its very architecture, how the brain generates its own suffering and reaches, in extremity, toward something beyond itself. You’ve explored how skin exposes vulnerability and how touch remains our most ancient form of communication. You’ve understood heartbreak as a genuine physical condition, and healing not as a cure but as the experience of being seen in pain.
By finding ways to bear witness to your own pain (and to the pain of others) you might find that suffering, for all its cost, leaves something behind: a deeper attentiveness, a harder-won empathy, and a closer relationship with being alive.
