Martijn shares lessons from Synthesis's rise and collapse, how time in the Himalayas reshaped his contemplative path, and why "ego porousness" may offer a healthier frame than "ego death." He and Paul discuss how Buddhist principles like interdependence and skillful means can guide responsible psychedelic work — and why awakening today must include service to a planet in crisis.

Martijn Schirp is a longtime Buddhist practitioner and founder of Upāyosis, where he leads A Path Between Worlds, a yearlong contemplative training blending Buddhist practice, ecological ethics, contemplative science, and optional psychedelic components.
