It is not always easy to navigate amongst the profusion of books that exist this kind of subject. This book is absolutely wonderful! It debunks many misconceptions, it is completely logical links between all the so-called "paranormal" phenomena and allows to see more clearly the world of the unseen, and therefore the world of the visible. Many things take on new meaning after reading it, it actually makes accessible the unknown universe that is the spiritual world. It is supported by impressive documentation and practical exercises. He also brings a strong message of humility, peace and love ... For me it was a real breath of oxygen. Feel free to read and reread!
