 Nor can we simply assume that mystics in the past must have had some pathology despite their lack of observable symptoms — a study of medieval Christian mystics and ascetics did not turn up evidence of any major forms of mental illness such as schizophrenia or manic-depressive disorder (Kroll and Bachrach 2005). Today mystical experiences have been correlated with healthy indices of personality and adjustment (Hood and Byrom 2010, Griffiths et al. 2011). Mystical experiences also more often correlate with positive changes in family life, reduced fear of death, better health, and a greater sense of purpose, although some patients do require therapeutic care, than do pathological experiences (Yaden et al. 2017, 59). The loss of a sense of self outside of mystical experiences is associated with maladaptive outcomes such as a sense of disconnection to other people and a loss of empathy (Yaden et al. 2017, 59). The pathology model does not explain any of this. It also makes emotion, rather than cognition, the central feature of mystical experiences, and this does not jibe with the historical record (Bradford 2013).
