This is a beautiful book about Mahayana Buddhism. Like all of the books I have read by Thich Nhat Hanh, it is written in a stunningly clear and lucid prose. He deals with very complex issues in a deceptively simple way. As a Vietnamese monk living in the South of France, he captures issues of the human condition with great precision. His story about his first love is poignant and thought-provoking.
If you are interested in Buddhism and have not read anything by this author I would urge you to try a book by him. This is a good place to start.
