I love Karen Armstrong. Her initiatives surrounding the Charter of Compassion and building compassionate cities are very important. If you're looking for 12 easy, cut and dry steps to follow to become a better person, then this book is not for you. But if you're interested in embarking on extensive study and a lovingkindness meditation practice - in other words, take a longer view of personal and world transformation - then you might find the book helpful. Armstrong's teachings on the importance of the Axial Age, and the seeming universality of the Golden Rule (Confucius was a big fan well before Jesus' day) were very enlightening for me. And while you're reading the book, check out Armstrong's Charter of Compassion website and Facebook page. They're helpful too.
