Letting Go: The Science and Art of Creating Space
Life has a way of filling up fast, doesn't it? We collect appointments, experiences, relationships, jobs, beliefs, material items and habits—some serving us beautifully, others lingering long past their time. I've been thinking a lot lately about the art of letting go and wanted to share some thoughts on the topic today.
The Wisdom of Nature's Cycles
Remember how trees release their leaves each autumn? They don't cling desperately to what once nourished them. Instead, they trust in the cycle, knowing that release is necessary before renewal can begin. The barren branches of winter aren't a tragedy but a necessary pause, making space for spring's new growth.
Interestingly, our own bodies understand this wisdom at a cellular level too. Scientists tell us that nearly every cell in our bodies is replaced over a span of roughly 7-10 years. Our skin cells renew every 2-3 weeks, red blood cells cycle every 4 months, and even our skeleton—which seems so permanent—regenerates completely over a decade. We are, quite literally, not the same person we were 10 years ago.
Yet despite this physical testament to renewal, we humans struggle with this wisdom that nature demonstrates so effortlessly. We hold on. To people, to possessions, to identities that no longer serve us. Sometimes until our knuckles turn white from the effort.
This week I’ve been decluttering the house. I found myself holding onto clothes that hadn't fit in years, attached to some future version of myself that might ‘need’ them. Nick-nacks I have never got around to repairing or recycling. Baby clothes my kids had long outgrown. Dust-collecting ornaments that served no purpose. Duplicates. Documents printed out but never read. Sound familiar? Our physical spaces often mirror our inner landscapes—cluttered with what no longer serves us but feels too precious to release. The clutter was building up and pressing on my peace. Decluttering has been a welcome cleanse and left the whole family feeling lighter. Once it’s done, I wonder why it took me so long to let go …
The Science of Attachment
Our tendency to hold on isn't just sentimentality—it's wired into our neurobiology. Attachment theory, pioneered by psychologist John Bowlby in the 1950s, describes how humans form emotional bonds. While Bowlby focused primarily on the bonds between children and caregivers, his work revealed something fundamental about human nature: we are wired for connection.
Our brains literally form neural pathways around our attachments - to people, yes, but also to possessions, routines, beliefs, and even expectations. These pathways create a sense of safety and predictability. When we consider letting go of something, our amygdala (the brain's alarm system) often activates, triggering fear responses. This is why letting go can feel not just emotionally difficult but physically uncomfortable.
Research in neuroplasticity, however, offers hope. Our brains remain adaptable throughout our lives. When we practice letting go, we actually create new neural pathways that make future releases easier. It's like cutting a path through an overgrown forest. It’s difficult at first, but becomes clearer with each journey.
What We're Really Holding Onto
Letting go isn't just about physical possessions, although those are often the easiest to identify. It's about:
Relationships that have run their course
Old dreams that no longer align with who we've become
Expectations about how life "should" unfold
Self-identities that have become too small
Control over outcomes we never truly had
Grudges that hurt us more than others
Perfectionism that keeps us from moving forward
Each of these attachments served us once. That relationship provided love when we needed it. That dream gave direction when we felt lost. That identity protected us when we felt vulnerable. Honouring what these attachments gave us is part of releasing them with gratitude and grace.
The Faith to Let Go
The hardest part I’ve found is that letting go requires faith; a belief that something equally meaningful (or perhaps even better) awaits in the space we create. We step into the unknown without guarantees, just possibility plus hope.
Studies in positive psychology suggest that this kind of faith isn't naive optimism but a powerful predictor of resilience. People who can trust in their ability to handle whatever comes next - who have what psychologists call "self-efficacy" - navigate transitions more successfully.
Where do we find this faith? I find mine in watching the seasons change, in conversations with friends who've bravely released their own attachments, in stories of others being courageous through challenges and change, in remembering previous times I've let go and survived—even thrived.
Sometimes I stand outside on clear nights, looking up at the vastness of the universe, and remember how small my grip on things really is. There's something comforting in that perspective.
The Identity Trap: Roles That No Longer Serve Us
Perhaps the most challenging things to release aren't physical objects but the roles and identities we've crafted for ourselves. These identities - professional titles, relationship roles, community positions etc., offer us structure, purpose, and the comfort of knowing who we are in a complex world.
I've experienced this firsthand. When I had my first child I held tightly on to the role of “Founder” alongside the new and unknown one of “mother” completely out of fear. The career title had become so intertwined with my sense of self. Who would I be without introducing myself as a Founder? How would people know I was hardworking, pioneering and competent? I wasn’t ready to let that role go - but I wasn’t doing it anymore, so what was my status and who was I now?
We cling to outdated roles for many reasons:
Security: A known identity, even an uncomfortable one, feels safer than the void of not knowing who we'll become next.
External validation: Certain roles come with social recognition and status that can be addictive and difficult to surrender.
Competence comfort: We prefer areas where we've already developed mastery rather than domains where we'll need to be beginners again.
Sunk cost fallacy: After investing years in developing a particular identity, walking away feels like wasting that investment.
Lack of imagination: Sometimes we simply can't envision alternative ways of being that might bring greater fulfillment.
This attachment to identity explains why career transitions, retirement, empty nesting, or the end of long-term relationships can trigger profound identity crises. These changes force us to confront the question: Who am I beyond this role?
Psychologist Carl Jung spoke about the second half of life as the time when we must shed the persona—the social mask—we've constructed and discover our authentic self. This shedding requires tremendous courage. We must be willing to stand temporarily undefined, to exist in the liminal space between identities.
But here's what I've discovered in my own journey and witnessed in others: when we finally release an identity that no longer serves us, we don't dissolve into nothingness. Instead, we often discover aspects of ourselves that were overshadowed by that dominant role—creativity, playfulness, curiosity, nurturing—qualities that have been waiting patiently for expression.
The Wisdom of Decluttering: Less Stuff, More Life
In recent years, minimalism has surged in popularity and for good reason. The physical act of decluttering often serves as a tangible entry point to the deeper practice of letting go. When I finally donated items like the clothes that didn’t fit and the books I'd read and been moving from house to for years, the relief was immediate and surprising. It wasn't just about having more shelf space; it was as if I'd put down a weight I'd forgotten I was carrying.
Research confirms this sensation. Studies show that people who live in cluttered environments experience higher levels of cortisol - the stress hormone - than those who live in more ordered spaces. Our physical surroundings and mental states are intimately connected. As the saying goes, "Outer order, inner calm."
But why do we accumulate so much in the first place? In part, it's because possessions provide a sense of security and identity. Our consumer culture encourages us to believe that "more" equals "safer." That extra pantry of food, the just-in-case clothes, the emergency supplies that far exceed any reasonable emergency .. these things make us feel prepared and protected. There's a primitive part of our brain that equates abundance with survival.
Our possessions also tell stories about who we are or who we wish to be. The unread self-improvement books, the unused exercise equipment, the aspirational kitchen gadgets (ahem, guilty) they represent possible selves we're not ready to relinquish. Letting go of stuff often means letting go of these possible identities, which can feel like a kind of death.
Yet those who embrace minimalism report increased mental clarity, reduced anxiety and more authentic relationships. Letting go brings lightness and freedom. When we're less focused on maintaining and managing our possessions, we have more energy for experiences and connections.
Ancient Wisdom on Letting Go
Buddhist teachings offer profound insights on the art of letting go. The concept of "non-attachment" or "aparigraha" sits at the heart of many Eastern philosophical traditions. Contrary to popular misunderstanding, non-attachment doesn't mean not caring - it means caring without clinging.
The Buddha taught that suffering (dukkha) arises from attachment (tanha) which is our tendency to grasp at pleasant experiences and push away unpleasant ones. This attachment creates a constant state of craving or aversion, preventing us from experiencing the peace of the present moment.
In yogic philosophy, aparigraha (non-possessiveness) is one of the five yamas or ethical guidelines. It invites us to take only what we need, keep only what serves us in the moment, and let go when the time comes. A yogi learns to hold life lightly; engaged but not entangled.
These teachings suggest that our attachments, whether to material possessions, relationships, outcomes, or even beliefs, create mental prisons. Freedom comes not from having everything we want but from wanting what we already have.
The Practice of Letting Go
Like any meaningful skill, letting go takes practice. Here are some approaches that have helped me:
Start small: Let go of a single item of clothing, an hour of scheduled time, a minor expectation.
Create rituals: Mark important releases with meaningful gestures. You could write a letter and burn it, plant something new, share the story with a friend.
Feel the feelings: Letting go often brings grief, fear, or anxiety. These emotions aren't signs you're doing it wrong; they're part of the process.
Embrace the space: Rather than immediately filling the vacancy, try sitting with the emptiness. Notice what naturally begins to grow there.
Connect with community: We weren't meant to navigate major transitions alone. Share your journey of letting go with people who understand its importance.
Practice gratitude: Thank the possession, relationship, or belief for what it gave you before releasing it.
Research on mindfulness practices shows that simply observing our attachments without judgment can loosen their hold. When we recognise "I am having the thought that I need this" rather than simply "I need this," we create space between ourselves and the attachment.
The Cyclical Nature of Life
In the end, letting go isn't something we do once and complete. Life is cyclical. Gathering and releasing, holding and letting go. Each time we willingly participate in this rhythm, we align ourselves with the natural order of things. … And on the cycle goes.
What are you holding onto that might be ready for release? What space are you being called to create in your life? Remember, the empty hands aren't a loss - they're readiness for what comes next.
