Dowsing, whose powers have always aroused enormous fascination, is based on the principle that all bodies emit radiation that can be captured with the help of a pendulum or a rod. This technique, besides being a diagnostic method used by alternative medicine, is also used to find water, lost objects and even people. It is true that it is not necessary to have a sixth sense to dedicate oneself to dowsing. However, a proper apprenticeship is indispensable. The simple exercises and knowledge provided in this book will allow you to become an excellent dowser. The objective of the works in this collection is to introduce you to the great themes of esotericism and hermeticism, as well as to promote the improvement of personal self-knowledge and the discovery of the universe around us.
