This ground-breaking work will change the way we understand religion. Period. Previous scholars such as Freud, James, Durkheim, and Maslow did not successfully identify the essence of religion as fear of death, mysticism, sacredness, communal bonding, magic, or peak experiences because religion has no single essence. Religion is about the values motivated by the sixteen basic desires of human nature. It has mass appeal because it accommodates the values of people with opposite personality traits. This is the first comprehensive theory of the psychology of religion that can be scientifically verified. Reiss proposes a peer-reviewed, original theory of mysticism, asceticism, spiritual personality, and hundreds of religious beliefs and practices. Written for serious readers and anyone interested in psychology and religion (especially their own), this eminently readable book will revolutionize the psychology of religious experience by exploring the motivations and characteristics of the individual in their religious life.
