Since its original publication in 1980, this book has become a classic in transpersonal psychotherapy. This new edition contains articles by the major figures in the field, including new contributions by Stanislav Grof, John Nelson, Donald Evans, Charles Tart, Edward Hoffman, Seymour Boorstein, W. Michael Keane and Stephen Cope, Sylvia Boorstein, and Roger J. Woolger. The articles present a spectrum of widely diverse perspectives—from precise behavioristic work with attention training, through creative clinical pharmacology and theory development, to innovative use of chakra energies. The result is a rich and provocative summary of the state of the art in transpersonal psychotherapy.The editor's focus is on the scientific healing/mysticism alliance, which dates back to the earliest shamans and in modern times has engaged William James, Carl Jung, Roberto Assagioli, and Abraham Maslow. In the book, some of the most respected pioneers in the field give their vision of the synergistic potential of these two powerful traditions. Transpersonal Psychotherapy describes a wide variety of uses of traditional and spiritual approaches for the alleviation of mental suffering and for spiritual development.
