I enjoyed the section of the book about suffering and "fixing" things. In our deluded states of mind we sometimes think we can "fix" all the worlds problems but as Buddha teaches, "suffering is inevitable." This can often lead people down one of two paths: 1). Become frustrated with the ever suffering world, disconnect from it and live a solitary existence. Or, 2). Acknowledge that no one can end all the suffering in the world but do things that reduce suffering.
In this regard Mattis-Namgyel recounts a story about a lady who devotes much of her time reducing the suffering of animals. One of her projects was to redesign stockyard and slaughterhouse facilities that reduce fear and stress in cattle. In reaction to this a radio interviewer asked her, "Why bother creating more humane conditions for animals that are about to be slaughtered anyway?" Her wise and compassionate response was, "Why else, but to reduce their suffering?"
Overall, I found the book to be a bit too elementary for my liking. That, however, doesn't mean I think it's a terrible book; because it does have some good insights. I simply think it is a book best suited for those new to Buddhism who are looking for a very basic over-view of the teachings. Although, I must say that if you're looking for a good over-view of the core basics of Buddhism I would point you in the direction of, "The Heart of the Buddhas Teachings: Transforming Suffering into Peace, Joy and Happiness."
