Ritual-based consciousness work in a professionally guided setting
From 26 to 29 November 2026, the Psychedelia Foundation is holding its first private retreat format in the Netherlands. It is aimed at people who want to work on personal development, life questions, and spiritual depth within a structured ritual framework.
The retreat is explicitly non-therapeutic and understands itself as a cultivated space of experience for self-inquiry and consciousness work. At its center is a structured process of preparation, ritual experience, and integration.
The retreat uses Psilocybe sclerotia (“truffles”), whose use in the intended setting is legally permitted locally. The format is clearly distinct from medical or therapeutic offerings. What is at stake here are responsibly designed ritual spaces, not the staging of an event. The experience alone is not what decides the matter. What is essential is how it is embedded in preparation and follow-up.
With a maximum of 16 participants, the retreat is deliberately kept exclusive, in order to allow individual guidance and a protected group process.
The retreat is led by the renowned psychonauts, researchers, and authors Claudia Müller-Ebeling and Markus Berger. Both have been recognized for decades as authorities on ritual cultures and ethnopharmacological traditions.
The Psychedelia Foundation places the format in the area of personal development and spiritual practice. It is aimed at reflective adults who want to engage with existential questions, biographical transitions, or a personal reorientation in a clearly structured setting.
An application and preliminary interview process ensures that participants bring the necessary maturity and personal responsibility.
