The odic force is a vital energy or life force that permeates all living plants, animals, and humans. The author was the first person to approach this force scientifically, having conducted hundreds of careful experiments. He began to work with people who were sensitive enough to accurately detect the polarity of magnets because they could see it. These people could also see the human aura—an energy field connected to the human body, plus detect an energy-related color spectrum that was directly linked to metals and minerals. He wrote this book as a simplified version of a more advanced text, making it easy for those who wish to grasp the subject.
