I've just started Rick Hanson's book, Buddha's Brain: The Practical Neuroscience of Happiness, Love and Wisdom. The book is about effective, research driven ways to light up the circuits in your brain that will bring you more joy, fulfilling relationships and inner peace.
I did the Community Dharma Leadership training at Spirit Rock with Rick and am impressed with his training as well as his sincere desire to get the word out on the fantastic research demonstrating how meditation impacts so many aspects of our lives.
As Rick writes in the book, "If you can change your brain, you can change your life."
