The book is dedicated to a little-studied and promising area of esoteric knowledge—bioenergy. You will learn about unique ways of interacting with the world of subtle energy and learn the practical use of bioenergy in everyday life to fill it with joy, inner understanding and direct knowledge. Sergey Ratner is the author of a unique method of working with energy, which he adopted from his father and improved. This is not a doctrine or dogma, it is a living skill that every person can develop and supplement based on their experience. The main principle of training is the unification of the spiritual and physical for a more effective life. The book was created based on Sergei Ratner’s speeches at seminars and lectures on energy management and contains answers to questions received from course participants.
