Interesting work, which was recommended by a friend who practices alternative medicine and relaxation. However, this is not a book for everyone. To appreciate it, one must have an open mind to all sorts of thoughts and not leave with a prioris. Personally, I'm always curious to learn something, to me positively or negatively analyzing my reading freely. We also free to retain only that we select according to our ideas. Warning, this is not a "novel", it is a book to consult according to our desires and our questions.
