Religious, spiritual, or mystical experiences triggered by psychedelic substances are rated as more intensely mystical and produce a reduced fear of death, a greater sense of purpose, and increased spirituality compared to similar experiences arising through other means. These findings held even after controlling for gender, education, socioeconomic status, and religious affiliation. The results support the view that psychedelic-induced experiences are genuinely mystical and generally positive in outcome.
People who report having had mystical experiences use language that is more socially and spatially inclusive—words like 'close,' 'we,' and 'with'—and fewer overtly religious terms such as 'prayed,' 'Christ,' or 'church' compared to those who have not had such experiences. This pattern emerged from quantitative linguistic analysis of 777 participants' written accounts of their most significant spiritual or religious experience. The findings suggest that mystical experiences, though often described as ineffable, can be meaningfully communicated, and that language analysis offers a way to study them.
