Query: Impossible to give zero stars

This is one of the five worst books I've ever read, and that does not include even Jane Austen or Adi Da or The Tao of Pooh-all very crappy, but not this crappy. The book averages three stars simply because the first 10-15 reviews were written by the authors and are 5 stars. Everyone else hates it for a good reason: it is terrible. This was my first book on the subject-luckily I have enough sense to know I am reading crap so I stopped at page 32 (perhaps more of a chance than it deserved), and will look for another book on this subject I am so eager to learn about. If you are thinking about getting this book, do yourself a favor: just read the first half of the first paragraph of the first chapter. If you like it, you will like the book!
