In the 2026 Yoga Medicine® Innovation Conference I shared Integrating the 5 Kosha Model: A Somatic and Neurophysiological Framework for Healing and Resilience in Breast Cancer Survivors.
Researching and preparing, I found myself standing—once again—at the intersection that has shaped my life: ancient wisdom and modern science. Speaking to the body we can measure and the signals we can feel, what is seen and what quietly organizes beneath the surface.
Yoga has always known something that medicine is only beginning to articulate: the our being is not a collection of parts, but a relational system seeking coherence and safety.
In the yogic tradition in which I did my initial teacher training Pranotthan Yoga, this understanding is expressed through the Koshas—five interwoven layers of being described in the Taittirīya Upanishad more than 2,500 years ago. Not as hierarchy, not as separation, but as relationship. Each layer shaping the others. Each layer inseparable from the whole.
Long before MRIs or biomarkers, yoga understood that what happens in the subtle body leaves fingerprints in the physical one.
As above, so below.
That phrase—often attributed to Hermes Trismegistus in the Emerald Tablet—was not meant as metaphor alone. It was an observation about reality itself:
- that patterns repeat across scales,
- that what is subtle informs what is dense,
- that what is unseen gives rise to what we can touch, creating the whole.
Centuries later, physicist David Bohm offered language that feels strikingly familiar to yogic philosophy. He described reality as unfolding between two movements:
- the implicate order—the hidden, enfolded intelligence beneath form
- the explicate order—the visible world of matter, structure, and experience
Nothing exists independently. Everything emerges from relationship.
When I look at the Koshas through this lens, I see the same truth expressed differently. The physical body and the thinking mind—our tissues, sensations, emotions, stress responses—live in the explicate order. These are the layers we can observe, treat, image, and diagnose.
The wisdom and bliss bodies—intuition, meaning, coherence, belonging—reside in the implicate order. Less visible, yet profoundly directive.
And between them flows prana—the breath, the nervous system, the energetic field that mediates between matter and meaning. The bridge. The weave. The currency of our being.
This is why yoga works where reductionism sometimes fails.
A posture is never just physical.
A breath is never just oxygen.
Awareness is never passive.
We are an integrative whole.
When we shift the field of understanding. the form responds.
In medicine, we are trained to intervene at the level of what is seen the body, and often the mind as an after thought. True healing requires a broader lens. Yoga reminds us that healing also depends on how safe a person feels in their body, felt sensed meaning they can access, the weaving of how coherent the inner and outer layers become.
The insight I am sharing is not to merge yoga and physics, or ancient wisdom and modern science, into something new. I’m simply naming what has always been true:
Healing is not linear or in fragmented parts.
The body listens to the breath.
The breath and nervous system listen for safety.
The mind listens for reassurance.
Wisdom listens for truth.
And at the core of our being, the system listens for coherence.
As above, so below.
