All religions describe spiritual experience as pleasant, and the goal of the religious pursuit as profoundly joyful. But many religions also condemn sensory pleasures and the desire for objects of pleasure. In this book, Ariel Glucklich resolves this apparent contradiction by showing how religious practices that instill self-control and discipline transform one type of pleasure into the pleasures of mastery and play. Using historical data and psychological analysis, he details how the rituals, mystical practices, moral teachings, and sacred texts of the world's religions act as psychological instruments that induce well-being. Glucklich also shows that in promoting joy and pleasure, religion also strengthens social bonds and enhances an individual's pursuit of meaning.
