Religious belief systems are often marked by internal dissonance. Mitigating this dissonance can lead to surprising religious phenomena, including blood libels, scapegoating, religious violence, the worship of saints and martyrs, asceticism, austerities, as well as processions, fasting, and clowning. In this study, Ariel Glucklich provides a new approach to understanding how religious actions emerge in the context of belief systems. Providing an innovative psychological and social understanding of the causes that stimulate believers to action, he examines a range of religious phenomena in India, Israel, Austria, Italy, and the United States. Glucklich's new theory enables recognition of the patterns that account for the full complexity of actions inspired by religious beliefs and systems.  His systematic comparison of actions across traditional boundaries offers a novel approach to cause and effect in comparative religion and religious studies more broadly. Glucklich's book also generates new questions regarding a universal phenomenon that has escaped notice up to now.
