Mystical Experiences Without Psychedelics and How Integration Improves Well-Being in Adults

The goal of this clinical trial is to evaluate whether a guided, non-drug spiritual intervention can facilitate mystical-type experiences and improve well-being in Christian adults. The main questions it aims to answer are: * Does the guided spiritual intervention produce measurable mystical experiences? * Does participation in the intervention and assigned integration program lead to improvements in well-being over time? Researchers will compare a Christian-based integration program to a structured control integration program to determine whether Christian-based integration leads to greater improvements in well-being. Participants will: * Complete baseline questionnaires assessing spiritual experiences, religiosity, and well-being * Complete one in-person session of the \"guided invocation for mystical experience\" * Be randomly assigned to complete either a Christian-based or control integration program for 4 weeks * Complete follow-up assessments at 1 month and 2 months
