About the book: 2003 / Russian readers have long loved A. Stangl's books "Pendulum: from illness to health" and "Secrets of the Pendulum". The third book by this German scientist and writer leads the reader from the simplest pendulum to an energy sensor - a simple device that allows you to record bioenergetic influences. With the help of such a sensor, you will be able to respond in a timely manner to manifestations of various diseases, avoid pathogenic zones, look for water in the country, and also learn to be more attentive to surrounding phenomena.
