This document discusses spiritually transformative experiences (STEs) and claimant mediums. It provides definitions of STEs, claimant mediums, and discarnate beings. The purpose and methodology of the study is to understand the initial and subsequent experiences of novice mediums and how they relate to spiritual transformation. The results found the STE of claimant mediums is a developmental process, with encounters with spiritual entities that may be considered guides. Acceptance of these experiences depended on social support systems and spiritual perspectives. Pursuing mediumship as a career depended on adjusting to initial experiences and available support.
