"The new edition of this successful text builds on the very latest research to present an original and unique exploration of the psychology of both spirituality and psychosis. The editor brings together fascinating perspectives from a broad range of distinguished contributors." (Studies in Spirituality, 2011) "This book is an updated and expanded version of a collection of essays first published about ten years ago, when some of the ideas it explores were fairly news ... This book is generally written at an accessible level, and draws on much useful recent research in this area. Section 5, entitled ‘Research', would be the most fruitful part for a non-specialist to sample." (The Way, 1 January 2012)"This book is aimed at anyone interested in the phenomenon of psychosis." (Mental Health Practice, 1 March 2011)
