From the publisher’s website: Anthropologists, exorcists and psychiatrists all approach the enigmas of spirit possession from differing perspectives and unsurprisingly fail to arrive at a consensual explanation for the phenomena. This creates problems for therapeutic interventions for perceived spirit possession cases. However, the 19th century researcher F.W.H. Myers developed a conceptual framework using rigorous scientific methods that provides a unified theory to explain all forms of spirit possession across all cultures, religions and societies. Myers declared that all so-called paranormal and supernatural phenomena are natural and normal, and all such experiences exist on a continuum of human experience. Discarded, forgotten and denied by mainstream science until now, Myers is being re-discovered by 21st century psychology. Using Myers’ scientific framework, this book fills the gaps in knowledge left by the inadequate theories of anthropology and psychiatry, and gives religious exorcism and clinical practice an alternative approach to research and intervention that is grounded in pragmatic and proven clinical experience.
