I found the book to be most interesting. I like the work on the various aspects of Tao, the explanation of Yin and Yang, the Pa Qua, the I Ching, Tai Chi Chuan, Chi Gong and more.
Everyone will find something of interest for them regardless and those sections that don't may be of interest sometime in the future.
The writing is excellant and easy to understand. You can see the relationships with other self_help mantra's as you read the book and most important the relationship to the Tao Te Ching by Lao Tzu.
Well worth the modest price new and more as a used book in excellant condition.
If you want hardcover you may have to go to barnes and noble but if softcover is ok then make sure you go Amazon (I ain't bein paid for this plug but I have purchased a few thousand dollars worth of books thru Amazon and have had nothing but pleasant experiences).
