Love is the great insulator from every ill which can attack the body. Love is the great balance wheel or spiritual gyroscope which makes it impossible for one to injure his own body by emotions which poison his body. Every emotion of any nature which is not based upon Love poisons the body and tears every nerve to the extent of the variance of that emotion from the balance which Love alone insulates one from.
He whose emotions are based upon Love commands the light-waves which compose his body. The most virulent pestilence could not touch one who is thus insulated by Love. He who eliminates Love from his thinking, and its consequent emotion, is slave to his body and exposes it to toxic dangers in the measure of his unbalance, and his mind to the ravages of unbalance which lead to insanity.
The principle which governs such variations is electric balance between both opposite pulsations of the heartbeat and their fulcrum from which they spring. All mental and physical illnesses arise from unbalance between these pulsations.
