Upon developing a Chakra instrument designed to detect minute electrical, magnetic and optical changes in the environment of a person, Dr. Motoyama conducted a scientific experiment on a normal person, and a yoga practitioner with experience in Chakra Healing.
After monitoring the centers of his test subjects’ stomach and heart, he found that the heart center of the yoga practitioner showed a considerable intensification of measurable activity during periods of concentration.
