These added capacities are made possible to man by the fact that he possesses a set of organs which have not yet been discovered by physical science. Although as yet unknown, they nevertheless have definite functions both in maintaining the health of the body and in enabling it to serve as an instrument of cognition and action. These organs exist in the mental and emotional bodies, and also in the etheric double of the physical body—the vehicle which was discovered by Dr. Kilner, and made partially visible by his screens. They are known by the names of “chakras”. The Sanskrit word chakram means a “wheel”, and is applied in this way because of the appearance of spinning vortices which these psychic organs, or force-centres, present to the clairvoyant sight. They provide the material for a separate study, and a book by C. W. Leadbeater, who is an authority upon this subject, has recently been published by the Theosophical Publishing House, Ltd.9 They are dealt with in some detail in Chapter VIII of this volume, and for our present purposes we may merely note that the chakras are situated as follows: The Root or Basic Chakram, at the base of the Spine. The Splenic Chakram, over the Spleen. The Umbilical Chakram, over the Solar Plexus. The Cardiac Chakram, over the Heart. The Laryngeal Chakram, at the front of the Throat.
