The authors warn us from the start. This book is not a novel, although the intention is romantic. What exactly is this unidentified literary object. A compilation of many theories, beliefs and experiences that open the door to another dimension, another level of understanding of our universe and our environment. The authors reiterate that they are not regularly newarticles gurus, they do not want to create any and wacky cult. No, they wonder about the extra-ordinary events, they open the field of possibilities. Cartesian minds will be put to the test, the other more open will be troubled by the stories we pretend extraordinary. We are not in a book by Bellemare. Here everything is checked, otherwise assumed and supported so t -it seems serious. The first part is devoted to alchemy and seems to be the least interesting. Then a long chapter is devoted to Nazism and its esotericism, specifically that of its leaders. Then vanished societies, and superman occupy a large frame of the book. What about the book appeared there 50 years. Certain facts are disturbing and deviate from the official history to bring, the claim of the authors, another angle of approach of history and science. Fantastic realism authors plunged me into a reflection on the human environnemnt and destiny, about the signs, the events we are picking sometimes without attaching more importance than that. Telepathy, télékynésie the dévellopement intelligence are among the topics discussed. Some will think that we are not far from X-Files, it is in my opinion a mistake. Never the authors bombard truths but disturbing possibilities. I had heard of this book, read it and some can disturb throw it over the shoulder or take it for a prank, on the other, like me, will see an opening, a bridge pier disturbing to other opportunities . Troubling sums up the spirit of this book.
