Spirituality and psychosis both inhabit the region where ordinary reason ceases to function and barriers break down. The connection between them is evident - what is remarkable is how conventional thinking obscures the connection. This volume challenges conventional understandings. The interface between psychosis and spirituality is explored, drawing on research and developments from a wide spread of disciplines. The 12 contributors include Gordon Claridge on schizotypy, Peter Fenwick on the neuropsychological perspective, Neil Douglas-Klotz on an understanding of spirituality, Peter Chadwick on the mystical side of psychosis, and David Kingdon on CBT for psychosis and religious disorders.
