Psychedelic work is not a one-size-fits-all endeavor.

It is a personal and ongoing relationship – shaped by timing, context, support, and readiness.

High-dose experiences can be profoundly meaningful for some in certain moments. For others, they can feel overwhelming or destabilizing.

This is why discernment matters. Ethical practice starts by listening: to your body, your mind, and that instinct that tells you when you’re at your capacity.

If you’re curious about what kind of approach may best support you right now, our Readiness Quiz offers a reflective starting point. It’s not a test or a recommendation—just an opportunity to slow down, consider key factors, and listen more closely to what this moment is asking for.

They say you can only guide others as deep as you’ve walked yourself.

Before stepping into psychedelic work, our retreat facilitator Mary spent years as a psychotherapist working at the edges of human experience: end of life, death and dying, bereavement, and profound transition.

These threshold spaces shaped her understanding of presence, listening, and what it means to walk alongside someone in moments of deep vulnerability and courage.

At Immersion retreat our team is made up of facilitators like Mary, who have explored the deep facets of this work and life’s most vulnerable moments themselves.

Their guidance is grounded in experience, integration, and humility to create a safe, supportive container for deep self-exploration.

If you’re ready to explore your edges with experienced, heart-led facilitators, we warmly invite you to explore our upcoming Immersion Retreats in New Eden, The Netherlands.

✨ February 18-22 | New Eden, The Netherlands
✨ April 26-30 | New Eden, The Netherlands

"I experienced a deep feeling of peace unlike anything I have ever experienced both in the moments I was in the ceremony and that reverberated in me for months afterwards. ” - Lisa

Since 2018, Synthesis Institute has supported over 1,100 individuals with legal truffle journeys offering a space to come home to themselves, connect more openly with others, and rediscover meaning in their lives.

Those who’ve walked this path often speak of a renewed sense of clarity, deep rest, and a sense of belonging they hadn’t felt in years.

Immersion is a 7-week arc of inner work that includes:
✨ 3 weeks of guided preparation
✨ A 5-day retreat with 2 truffle ceremonies
✨ 3 weeks of integration and support

Curious to experience it for yourself?

They’ve shaped life for millions of years — now it’s time to meet them with intention.

Meet The Mushroom is the first module in our 13-month professional certificate program, the Psychedelic Practitioner Core Training.

This introduction to mycelial intelligence invites practitioners into right relationship with the mushroom through curiosity, reverence, and deep listening.

One of nine core modules explored over nine months, each builds upon the last to develop the foundational competencies essential for ethical, legal, and professional psychedelic facilitation.

If you’re exploring psychedelics as a vocational path and want to experience a training grounded in embodied and relational learning, we invite you to explore the Psychedelic Practitioner Core Training.

👉 The training begins January 19, 2026
