Abstract

This paper examines how unrecognized trauma can create inner isolation within communal spiritual life, even when outward participation appears steady and devoted. Drawing from participant-shared narratives within the Santo Daime tradition—an ayahuasca-based Christian syncretic movement—it explores how altered states may amplify unresolved survival responses that are often misread as spiritual phenomena, resistance, or culturally valued steadiness. A nervous-system foundation of trauma (hyperarousal, constriction, dissociation, freeze) is outlined, showing how these states can go unrecognized within devotional practice. Through lived stories, the paper offers a window of understanding, invites discernment, and provides guidance for leaders and participants seeking to foster belonging.
