Not Necessary for the Cleanse
Book one is very helpful for doing the cleanse, and answers a lot of questions that aren't found in the free download of the cleanse guide on the Arise and Shine site. However, book two was not useful for me, as the author is fairly fanatical about his beliefs, and he tends to go on endlessly expressing his views with absolute conviction. Perhaps someone who doesn't mind wading through pages of opinion, may find something of value in this book.
