The greater development in healing power is to be able to send power to a distance. No land nor sea can prevent power being sent by the mind. Scientific discoveries such as wireless telegraphy prove that by means of instruments thoughts can be sent to a distance, but the mystic has always realized and practiced to a great extent the sending of thought to a distance. As the whole idea of a mystic is to serve humanity by love and goodness, he naturally does not feel inclined either to prove to the world the greatness of his power or to utilize His power for any worldly end except for healing.
