When was the last time you really smiled?
Not the polite, tight-lipped acknowledgment for a coworker, but the kind of smile that starts deep in your belly, rushes up, and bursts onto your face, making your eyes crinkle and your whole being feel lighter.
In their work on energy medicine, Donna Eden and David Feinstein capture this phenomenon perfectly:
“When you smile from a deep natural space, it sends joy all the way down to your soul and up again. A deep smile is not an ornament or a mask. It engages your radiant energies. So does listening to music you love, being overtaken by beauty, reveling in nature, laughing uncontrollably, abandoning yourself to play, love, or dance…”
This quote is a profound invitation. It suggests true joy isn’t a passive state but an active, energetic engagement with the world. The “deep smile” is the gateway to what Eden and Feinstein call our “radiant energies”—our essential aliveness and glow.
This isn’t just poetry. This concept of authentic joy is a holistic experience. To understand its power, we must look at it from every angle: biological, psychological, social, and spiritual.
The Biological Symphony: What a “Deep Smile” Does to Your Body
Our bodies are not separate from our emotions. A “deep smile” is far more than muscle movement; it’s a powerful biological event.
This genuine smile is known as a “Duchenne smile.” It’s specific: it involves not just the muscles that lift the corners of your mouth but also the muscles that involuntarily crinkle your eyes.
You can’t fake the eye-crinkle. That’s the “deep natural space” part.
When you execute a Duchenne smile, your brain receives a signal that you are safe and happy, triggering a neurochemical cascade of:
- Endorphins: Natural pleasure-enhancers.
- Dopamine: The “reward” chemical.
- Serotonin: A key mood regulator.
Simultaneously, this act reduces stress hormones like cortisol. The phrase “sends joy all the way down to your soul” could even describe the vagus nerve. This nerve network connects your brain to your major organs. A genuine smile or laughter stimulates this nerve, activating your parasympathetic nervous system—your “rest and digest” state. It tells your entire body to relax and restore.
This isn’t limited to smiling. “Abandoning yourself to play, love, or dance” floods the body with this same positive cocktail. Laughing uncontrollably is cardiovascular exercise. Reveling in nature lowers blood pressure. These are essential biological maintenance.
The Psychological Reset: Reclaiming the Present Moment
Psychologically, the “deep smile” is the ultimate act of presence. The quote draws a sharp line between this smile and a “mask.” A mask is a tool of the ego for social management, rooted in the past or future.
A “deep smile” can only happen now.
This is where the quote’s other examples—”being overtaken by beauty,” “reveling in nature”—become so potent. These experiences define a flow state, a concept from psychologist Mihaly Csikszentmihalyi. Flow is the state of being so completely absorbed in an activity that your sense of self, time, and worry dissolve.
- Being overtaken by beauty: Your analytical “mask” maker shuts down, leaving only awe.
- Laughing uncontrollably: You are not deciding to laugh; laughter is happening to you.
- Abandoning yourself to play or dance: You are no longer self-conscious. You are simply being.
This “abandonment” is the antidote to anxiety, which is rooted in ruminating on the past and worrying about the future. These moments of authentic joy are psychological resets. They break the ruminative loop and anchor us in the present.
Furthermore, the facial feedback hypothesis suggests this street goes both ways. While joy causes a deep smile, a deep smile can also cause joy. By consciously choosing to engage in these activities, or even by holding a genuine, eye-crinkling smile while thinking of a happy memory, you can initiate the psychological feeling of joy.
The Social Contagion: Why Your Radiance Connects Us
We are profoundly social creatures. A mask creates separation. A “deep smile” is a bridge.
This is the work of mirror neurons. When you see someone experience a genuine emotion, your brain fires as if you are experiencing it. When someone gives you a deep, Duchenne smile, your mirror neurons fire, and you instinctively want to smile back. You feel a flicker of their joy. You perceive them as warmer and more trustworthy.
This is the social power of “radiant energies.” It’s a tangible, neurobiological phenomenon. A person who genuinely revels in life is socially magnetic. Their energy radiates outward and invites others in.
- Laughing uncontrollably: It’s almost impossible to be near genuine laughter and not feel something positive.
- Dancing: This is a primal form of group bonding.
- Love: This is the ultimate shared, radiant state.
When we wear a “mask,” we force superficial connection. When we offer a “deep smile,” we offer our authentic selves. We are non-verbally saying, “I am safe, present, and open to connection.” This is how deep bonds are formed. Your joy is a gift to everyone you meet.
The Spiritual Alignment: Touching Your Soul’s “Yes”
Finally, we arrive at the “soul” and “radiant energies.” This is the spiritual dimension.
“Spiritual” here refers to the part of you beyond your job title, roles, and ego. It is your essential self, your life force.
The “mask” is a sign of misalignment. It’s when your inner state (bored, tired) doesn’t match your outer expression (a polite smile). This dissonance is exhausting, leaking your “radiant energy.”
A “deep smile” is a moment of perfect spiritual alignment. Your inner state and outer expression are one. There is no friction, only truth. This is why it “sends joy all the way down to your soul.” It’s an act of profound integrity, where your body, mind, and soul are all saying: “Yes.”
The other activities are spiritual practices:
- Reveling in nature / Being overtaken by beauty: These are experiences of transcendence. They silence the ego and connect you to something larger than yourself, reminding you that you are part of a beautiful whole.
- Abandoning yourself: This is the spiritual act of surrender. It’s letting go of control, a core practice in many wisdom traditions. You surrender to the music, the game, the moment.
- Listening to music you love: Music bypasses the rational mind and speaks directly to the soul.
These actions are how we practice alignment and “engage” our radiant energies. Joy is not frivolous. It is a sacred, spiritual imperative. It is your soul coming fully online.
Your Daily Practice: 5 Ways to Engage Your Radiant Energies
How do we cultivate this in a life of spreadsheets and to-do lists? We must practice by creating small, intentional moments.
- The 60-Second “Beauty Hunt”: (Connects to “overtaken by beauty” )Once a day, stop and actively search for one small, beautiful thing. Don’t just note it; revel in it. The way light hits a glass, the pattern on a leaf, the color of your coffee. Stare at it for one full minute and let yourself be “overtaken.”
- The “Anthem” Pause: (Connects to “listening to music you love”) Create a playlist of 3-5 songs that bring you pure joy. When your energy flags, put one on. Close your eyes. Don’t multitask. Just listen. Let it be a 3-minute energy elixir.
- The “Abandon” Micro-Dose: (Connects to “play, love, or dance”) Schedule 5 minutes of “useless” play. It must have no goal. Dance wildly in your kitchen. Toss a ball against a wall. Make silly faces at your pet. Give yourself permission to be gloriously unproductive and “abandon” your responsibilities for a tiny window.
- The “Laughter” Scan: (Connects to “laughing uncontrollably”) Joy needs fuel. Your brain has a negativity bias, so you must actively seek the positive. At the end of your day, find one thing that was genuinely funny or delightful. Tell someone about it. Actively seek out comedy that makes you laugh.
- The “Gratitude” Smile: (Connects to the “deep natural space”) This is a direct Duchenne smile practice. Stand in front of a mirror. Force a “mask” smile; feel the tension. Now, relax. Close your eyes and think of one thing you are deeply, genuinely grateful for. Feel the emotion. Now open your eyes and see your “deep smile.” Notice the difference in your eyes.
Your Radiant Invitation
The “deep smile” is not an ornament. It is an engine—the visible sign of a life lived from authenticity and presence.
Donna Eden and David Feinstein’s words are a call to action. They remind us that well-being is not a problem to be solved, but an energy to be engaged.
Here are the key takeaways:
- Biologically: A genuine smile releases feel-good chemicals that heal your body and reduce stress.
- Psychologically: Authentic joy and play pull you into the present, breaking the cycle of anxiety.
- Socially: Your deep smile is contagious, bypassing masks to build trust and connection.
- Spiritually: Joy is the sound of your soul in alignment; engaging in beauty, play, and love is a spiritual practice.
So, your invitation today is this: Find a way to engage. Don’t wait for joy. Hunt for beauty. Put on the song you love. Revel in the sky. Abandon yourself to play. Let go of the mask, even for a second, and feel the undeniable, powerful, and radiant energy of your own deep, natural smile.
