Award-winning science writer Dawson Church focuses on positive and negative moods in his new book. In just eight weeks of meditation practice, 12 minutes a day, brain remodeling begins, he says. Over time, these structural changes in brain anatomy make us calmer, happier, and more resilient. We don’t just feel more blissful as a temporary state, the changes are hard-wired into our brains, becoming stable personality traits. The book includes numerous “Deeping Practices” that apply this brain science in a practical program of self-transformation. The foreword is by Dave Asprey, of “Bulletproof” fame.
