Book excerpt: A multidisciplinary team of scholars shows how spiritual and religious practices actually do power psychological, physical, and social benefits, producing stronger individuals and healthier societies. In recent years, scholars from an array of disciplines applied cutting-edge research techniques to determining the effects of faith. Religion, Spirituality, and Positive Psychology: Understanding the Psychological Fruits of Faith brings those scholars together to share what they learned. Through their thoughtful, evidence-based reflections, this insightful book demonstrates the positive benefits of spiritual and religious engagement, both for individual practitioners and for society as a whole. The book covers Buddhism, Christianity, Islam, Judaism and other major traditions across culture in two sections. The first focuses on ways in which religious and spiritual engagement improves psychological and behavioral health. The second highlights the application of this knowledge to physical, psychological, and social problems. Each chapter focuses on a spiritual "fruit," among them humility, hope, tolerance, gratitude, forgiveness, better health, and recovery from disease or addiction, explaining how the fruit is "planted" and why faith helps it flourish.
