A very good book can be read both as a pure adventure story and as initiatory book. The different themes are so quite interesting in the sense that each is described by an initiator and then directed by the hero in turn. Truly, the reader can not help but take the game and live the quest simultaneously with the hero. Like the latter, we find ourselves launched into a huge spiral quest for knowledge of life and the things around us. A real upheaval in your life! Recommend!
