...This book is more than a little bit "fluffy." Perhaps a problem with stating basic profound truths that they are all pretty obvious; "Things are what they are." Depending on your perspective, that's either deep or shallow.
Still, Zen 24/7 provides perspectives on zen in our daily lives, and can serve as a good reminder to pay attention and think of the possibilities for spiritual awakening in everyday life.
This is a good book to flip through. You can read the segments in any order, and they are nice to fill up spare moments of waiting. But if you read too many of them in a row, they all start to seem the same.
I'd say this is a good book for a zen afternoon snack, but for a complete zen meal, check out Janwillem van de Wetering, Thich Nhat Hanh, Maurine Stuart, or Geri Larkin.
