Witnessing without judgment

Present Moment Awareness

The current paradigm we are living within

Zach Bush holds something rare, the willingness to look directly at collapse and call it a beginning. He doesn’t flinch from the data: soil death, microbiome loss, the unraveling of systems we built our certainty around. But he refuses to stop there.

For Zach, the wound is the portal. Disease is not the enemy, it is the body’s intelligence, speaking in the only language we left it. And what is true in the cell, he says, is true in the civilisation. We are not dying. We are composting. Turning. Becoming something we don’t yet have words for. His invitation is not to fix the world. It is to trust the process that made it.

What the Soil Remembers

The Initiation

 Come Back to Earth

To retreat with Zach is to stop managing the crisis — and finally feel it. Not as catastrophe. As initiation. He will not hand you a programme or a protocol. He will walk you into the soil, into the silence, into the body you've been too busy to inhabit — and ask you to listen there. The contraction you've been running from becomes, in his presence, the very thing that opens you. You don't leave with answers. You leave having remembered something older than the question.

Soil. Gut. Consciousness.

The Thread Back

Where Healing Begins

He has spent decades at the intersection of soil, gut, and sky — tracing the same intelligence through all three. His three pillars are inseparable: the microbiome as the body's first language, the soil as the source we severed ourselves from, and consciousness as the field that holds it all. Lose the microbiome, you lose the ability to feel. Lose the soil, you lose the microbiome. Lose consciousness — true presence, embodied awareness — and you lose the thread back to both. For Zach, healing was never about the symptom. It was always about the disconnection. And reconnection, he has found, begins the moment you put your feet back on the earth.

A retreat with Dr. Zach Bush

The Body Knows

Of what the Earth has never forgotten

There is a moment — most of us have felt it — when the body knows something the mind has not yet caught up to. A tightening in the chest before the diagnosis. A grief that arrives before the loss. Zach Bush has spent his life at that threshold. First as a physician watching patients heal in ways that defied the textbook. Then as a scientist tracing the invisible thread between a handful of living soil and a living human gut. What he found — and what this retreat asks of you — is that healing is not a destination. It is a remembering. Of what the body already knows. Of what the Earth has never forgotten.

The Doctor Who Followed the Thread

On grief, soil, and the species we are becoming

What Zach Bush sees that most of us are only beginning to feel

The Threshold

There is a particular kind of physician who cannot stay inside the clinic. Who follows the illness back through the body, back through the gut, back through the food, back through the soil — and arrives, finally, at a civilisation that forgot it was alive. Zach Bush is that physician. What he brings to Origin is not a protocol or a prescription. It is a reframe so complete it changes what you see when you look at the news, at your own body, at the ground beneath your feet. The crisis, he will tell you, is real. The grief is necessary. And on the other side of both — closer than we think — is a species remembering what it was always capable of.

This is where you should go to destress from your travels! I have taken 2 yoga classes from Shiva so far. He is phenomenal. The class is in perfect English. The atmosphere is beautiful and calming. The studio is pristinely clean. Shiva knows how to ease you into a meditative state that will provide you with the most satisfying yoga experience you could hope for. Classes are $10 and worth every penny. Shiva chants throughout the class and helps students stay on track with deep breathing in sync with the movement. Thank you Aum yoga for providing this extraordinary yoga class! I can’t wait to come back for more!

I joined several classes at Aum Yoga while I stayed in Siem Reap. I tried different styles and workshops and I was lucky to meet all their teachers. Always professional and warm, I felt like at home from first day. They also have an amazing range of Crystal Singing Bowls that often are used at the end of the yoga class, or as a complete session on their Saturday schedule. Once I had the opportunity to take a private class with Shiva, so knowledgeable and experienced yoga instructor! Once a month they also offer community event Kirtan. Well equipped, clean and cozy, I dare to say this probably is best yoga studio in town.

This yoga lesson was an amazing experience. The class had a serene and welcoming atmosphere first thing in the mornigng. The instructor's teaching was knowledgeable and passionate, making the class accessible even for beginners like me. The asanas were a perfect blend of strength and flexibility, with modifications offered for all levels. The spiritual aspect of the class, including guided meditation and chanting, left me feeling centered and rejuvenated. Overall, it was a transformative and enriching yoga experience that I highly recommend to others. Thank you Shiva!

Everything You're Wondering

A triple board-certified physician in Internal Medicine, Endocrinology, and Palliative Care — and one of the most original thinkers working at the intersection of human health and planetary regeneration.


His patients led him there. Treating end-stage cancer and chronic disease, he kept finding the same root: a broken relationship between the human body and its microbial environment. That thread led directly to the soil.


That soil health, gut health, and human health are not separate conversations. Heal the soil and you begin to heal the person. Heal the person and you begin to heal the planet.

The organisation Zach founded to unite the world’s regenerative nonprofits into a single connected organism — functioning like the mycelium beneath a forest floor, unseen but essential.

That humans are not inherently destructive. A keystone species increases biodiversity wherever it goes. Zach believes that is our true nature — and our greatest unrealised potential.

Because he sees grief not as weakness but as the doorway to love. In his hospice work he witnessed it repeatedly — the letting go that opens something new.
