Internal Family Systems (IFS) meets the transformative insights of psychedelic-assisted therapy in this groundbreaking guide from Dr. Nicholas Brüss, leading expert in this emerging field, revealing how trauma, anxiety, emotional disconnection, and survival patterns can begin to soften—with or without psychedelics.

We’re on the cusp of a seismic shift in mental health: more than 75% of patients improved on psilocybin for depression, and more than 70% on MDMA for PTSD. Psychedelics have proven themselves powerful accelerants for personal growth and healing.

What if you could access those results, without psychedelics?

Dr. Nick Brüss has spent twenty years as a therapist, and the last decade inside that question. As an Internal Family System (IFS)–certified therapist and supervisor on the FDA’s Phase 3 trials of MDMA for PTSD and as a lead therapist on Compass Pathways’ Phase 3 psilocybin trials for treatment-resistant depression, he has helped shape the very research behind these results. He’s also worked with hundreds of clients in ketamine-assisted sessions. What he’s learned is the central claim of this book: the medicine isn’t the medicine.

The conditions psychedelics create—openness, presence, and connection—aren’t just manufactured by the molecules. They’re a cultivable mindset. In The Psychedelic Mindset, Dr. Brüss draws on IFS, trauma research, and contemplative traditions to translate what happens in a successful psychedelic session into a guided framework anyone can practice.

In this first-of-its-kind book, you’ll discover:

• Why true transformation is mediated by a state, not a substance
• The five core survival mindsets—Fight, Flight, Freeze, Fawn, Flock—and how to recognize your own
• How to cultivate Atomic Willingness: the smallest unit of transformation
• How to safely choose, prepare for, and integrate psychedelic-assisted work, if you choose that path
• Why the goal isn’t to feel better. It’s to get better at feeling.

Grounded in the latest science and complete with actionable tools, The Psychedelic Mindset offers what no other book in this growing field has: a path to the healing psychedelics promise—accessible to anyone, with or without the medicine.
