God is great--for your mental, physical, and spiritual health. Based on new evidence culled from brain-scan studies, a wide-reaching survey of people's religious and spiritual experiences, and the authors' analyses of adult drawings of God, neuroscientist Andrew Newberg and therapist Mark Robert Waldman offer the following breakthrough discoveries: - Not only do prayer and spiritual practice reduce stress, but just twelve minutes of meditation per day may slow down the aging process.- Contemplating a loving God rather than a punitive God reduces anxiety and depression and increases feelings of security, compassion, and love.- Fundamentalism, in and of itself, can be personally beneficial, but the prejudice generated by extreme beliefs can permanently damage your brain.- Intense prayer and meditation permanently change numerous structures and functions in the brain, altering your values and the way you perceive reality. Both a revelatory work of modern science and a practical guide for readers to enhance their physical and emotional health, How God Changes Your Brain is a first-of-a-kind book about faith that is as credible as it is inspiring.
