First read this book in 2007. It seems "all" understand, we find it rather interesting, even curious, so it seems "simple". Then comes the moment when you decide to read the book (why ...?); once, twice ... and something happens. Yet I do not like read a book, but there is more than a book: it is a bomb. Once we really fall in the moment, something opens and we can not go back, thinking "as before." A REAL spiritual awakening guide. This has become my favorite book, with New Earth, also a wonder to offer everyone! Everyone should read these two books. Humanity needs this kind of "shock" now.
