I see this book is being offered on consignment at this website for $86 and $111. It's a paperback. Does that say something about its value? Well, I don't know who would pay that much for it....I found my copy in the trash, with mildewed pages and slightly waterlogged. You can have it for the cost of shipping.
Judging from her works listed on this website, this author looks like she has made quite a writing career by remarking on the Tao. In this book, she recites a verse or two of Lao Tse's work, and then gives examples from among her friends and acquaintances. She gives personal exercises and "affirmations," or self-statements. To me, all of these were almost totally worthless. It's not like they were new to me: they weren't. Everything seemed like recycled garbage, and maybe that's her point, to recycle garbage.
The Tao itself is a great book, that's understood. What Dreher does to it here is not great. However, her book is not without some value. It will make you think, but I think if you had just read the Tao itself you would get the same value. No need for her quite pedestrian and quite unnecessary commentary. This is not like some of the other Tao commentaries I have read, which I have enjoyed.
I will say this: Diane Dreher, the way she comes out in this book, is one of those hippy-types who has forged a career for herself as a kind of flower child capitalist. This to me stinks of hypocrisy, and that's another reason I didn't enjoy this book. Sorry. Diximus.
