For a graduate school class on meditative practices, I used this book for an experiment. I took the verses and memorized many, and changed the rest to suit my particular situations. I made up new verses -- in the same style -- to complement situations not described in the book. I found this to be an effective way to minimize my daily stress. As just a book for your nightstand, this one will probably not be useful or very interesting. But for someone with stress or anxiety, or someone just interested in Eastern religions, it may be invaluable. Such a collection is certainly not easy to find, and the writing is clear and unambiguous.
These gathas/short poems are interesting and helpful for those who already practice meditation, but may seem skimpy and repetitive to those not already trying to pursue mindfulness.
Don't get this book if you are looking for an introduction to Buddhist thought--get it if you are looking for daily techniques to improve your appreciation of the miracle of daily life.
