Why this free summit exists (a 1967 paper explains it)


Dear Reader

In 1967, psychologist Julian Silverman published a paper with a curious title:

Shamans and Acute Schizophrenia.

It's a question close to the heart of the online summit coming up: what happens when people move through reality-altering experiences that the world around them understands completely differently?

Silverman argued the real difference wasn't only what happened inside the person, but what happened around them.

Was there a cultural map?

  • Was there a (safe) place for the experience?
  • Were there people who knew this terrain?
  • Could what happened be understood, integrated, and woven back into a life?

Or was it met primarily as evidence that something had gone terribly wrong?!

In practice, it may look the same on the surface: hearing voices, sensing information from beyond ordinary time and space, the dissolution of a fixed sense of self... What differs is the perception.

In The Netherlands, or any state of the US, that gets you a label and a prescription.

In South Africa, Peru, or Tibetan Buddhism, the same experience can become the beginning of an initiation — because those cultures carry a lineage to catch a person.

I don't think shamanic states and psychosis are simply the same thing — later scholars pushed back on that comparison too.

But one question underneath that old paper still feels incredibly alive to me:

"How much does the way we receive an altered state, shape what it becomes?"

This is exactly the kind of question I want us to bring into the online summit that starts October 15th.

Not one explanation. Not psychiatry or spirituality.

But psychiatry, lived experience, animism, and ritual — meeting each other, finding common ground.

This summit isn't something I want to create for people from a distance. I want us to build the conversation together!

I write about mental health, psychosis, altered states, trauma, yoga therapy, nervous system regulation, philosophy, spirituality and the many ways people find their way back to themselves. My work lives at the meeting point of psychiatry, psychology, yoga, ancient wisdom traditions and what I call Original Medicines: the practices, relationships, rhythms and ways of knowing that reconnect us with body, community, nature and meaning. After more than 25 years working in mental health as a psychiatric nurse, therapist and yoga therapist, I’m especially interested in what becomes possible when we widen the conversation beyond diagnosis and symptom reduction — without losing discernment, safety or good clinical care. Through Terrapy, I work with individuals and groups and teach healthcare professionals, therapists and others who care. I also share reflections from my books, research, conversations, trainings and the questions I’m currently exploring.If you’re curious about a broader, more humane and integrative approach to mental health and healing, you’re very welcome!

5 min read · Full (hunter's) moon | October 26, 2026 Every transformation has a moment when the old way of being stops working. The ground crumbles. What held you (the roles, the certainties, the masks, the story of who you are) loosens its grip. And there is nothing yet to replace it. Like a free fall into a never-ending depth. The Greeks called it katabasis: the necessary going down into the underworld, the un-doing before again becoming. I know this place. I have gone through it, and I...

Dear Reader, When I first started imagining this summit, I didn't begin with keynote speakers. I began with circles. I wanted to turn the usual conference model a little upside down — not four days of sitting behind a screen listening to expert after expert, but a living gathering where you can enter the conversation yourself. So throughout the summit there will be live circles — smaller, facilitated spaces built around shared experience. Some are pure experience, like Gaby's drum circle,...

Hey there Reader, It started as a little fun idea, as it always does (if you know me)... A seed was planted. I started speaking with people who crossed my path — and I couldn't have imagined how beautiful this summit would become. So let me tell you what it's grown into. Expect more than interesting names — expect what happens when different ways of knowing meet in the same room: psychiatry beside animism, yoga beside consciousness research, lived experience beside clinical practice, grief,...
