I fully supports the shamanic vision we present Arnaud Riou. This is informed shamanism. This book is full of various information, offers practical exercises and tracks for reflection / meditation on our behavior, our worldview. It opens doors may be closed, and we certainly opens windows, not on another reality, but on another way of conceiving this reality. Everything is extremely pleasant to read. Needless to say I highly recommend this book. To note, another approach but again the final "open doors and windows" in the book of John Paul Joguet Lawrence CARDS IN HAND. Arnaud Riou thank you!
