This book is a collaboration of Dr. Cutler and the Dalai Lama. Most of the book is Dr. Cutler's opinion and words, and unfortunately not much is left for the Dalai Lama.
Compassion is highly stressed in this book (especially the first half) and although I agree with what is said about compassion, the book gets quite exhausting by conveying the idea over and over. I feel more insight can be gained from books such as "Open Your Mind, Open Your Life: A Little Book of Eastern Wisdom" by Taro Gold which is also full of Buddhist wisdom and thoughts on the art of happiness.
