Book excerpt: This three-volume set addresses how the role of spirituality and its constructive expressions in various religions—and outside of formal religion—enhances human personality and experience. Theologian and acclaimed scholar J. Harold Ellens now offers a breakthrough work on the positive impact of faith. In The Healing Power of Spirituality and Religion, an extraordinary group of scholars discuss the latest scientific research into the connection between belief and psychological and physical well-being. Each volume of The Healing Power of Spirituality focuses on a specific aspect of the scientific exploration of faith and well being: volume one examines the healing power of personal spiritualities like I Ching and Transcendentalism; volume two looks at the subject in the context of Christianity, Judaism, and other world faiths; and volume three explores the psychodynamics of healing spirituality and religion, including the role of biochemical and chemical reactions in heightening psychospiritual apperception.
