Newberg and Waldman on the brain

Here is a quote from How God Changes Your Brain by Newberg and Waldman:

Some people put their faith in God, while others put it into science, relationships, or work. But wherever you choose to place your faith, you must still confront a deeper question: What is your ultimate purpose and dream? What do you really desire in your life -- not only for yourself, but for the world as well? And how will you begin to make that desire a reality? Having hope and faith are essential, but something more is needed: the skill and discipline to organize your brain in ways that will successfully motivate your life. Our meditation studies have provided a few basic tools that can help you achieve those goals, and if you apply them to your life, not only will you find a little more happiness, you'll bring a little more peace into the world.
