Book excerpt: Drawing on cutting-edge research, friends and Harvard collaborators Daniel Goleman and Richard Davidson expertly reveal what we can learn from a one-of-a-kind data pool that includes world-class meditators. They share for the first time remarkable findings that show how meditation - without drugs or high expense - can cultivate qualities such as selflessness, equanimity, love and compassion, and redesign our neural circuitry. Demonstrating two master thinkers at work, The Science of Meditation explains precisely how mind training benefits us. More than daily doses or sheer hours, we need smart practice, including crucial ingredients such as targeted feedback from a master teacher and a more spacious worldview. These two bestselling authors sweep away the misconceptions around these practices and show how smart practice can change our personal traits and even our genome for the better. Gripping in its storytelling and based on a lifetime of thought and action, this is one of those rare books that has the power to change us at the deepest level.
