And so we may rise from grade to grade of inspiration until we reach the stage at which the mind and emotions of the man no longer sway his body, but the body is wholly taken possession of and used by One greater than himself. Then it is no longer the man himself who speaks, but “the Spirit of” his “Father who speaketh in” him; his own limitations are struck away, his own idiosyncrasies vanish, and the inspired utterances flow forth unsullied. Then inspiration may range into revelation. The process of all this is a very simple one. We know that by the correlation between changes in consciousness and vibrations of matter, each change in consciousness is accompanied by a vibration of the matter appropriated by the consciousness and forming its body; each vibration of the matter of a body is accompanied by a change in the embodied consciousness. Either one of the pair may be the initiator; the other ever responds. When two or more people are together, one more evolved than the other or others, the more evolved person, thinking, desiring, acting, sets up in his own bodies, mental, astral, and physical, a series of vibrations which corresponds to the changes in his consciousness; these vibrations cause similar vibrations in the mental, astral, and physical matter intervening between himself and the less advanced person or persons present. These vibrations in the intervening matter cause similar vibrations in the neighbouring body or bodies. These vibrations are immediately answered by corresponding changes in the embodied consciousness or consciousnesses, and the person or persons concerned, thus placed _en rapport_ with one more advanced, think, desire, act on a higher level than would be possible for them on their own initiative. They are able to understand more keenly, to feel more warmly, to act more nobly than they could do unassisted. When the stimulus is removed they gradually sink back to their normal level, but memory is left, and they remember that they “have known.” Moreover, it is more easy for them to respond a second time, and so on and on, until they establish themselves on the higher level permanently. Hence the value of companionship with those more advanced than ourselves, of living “in their atmosphere.” Words are not necessary; little speech may pass; but insensibly the subtle body is tuned to a higher key, and only, perhaps, when the companionship is interrupted do the younger become conscious of the change which has thus been brought about by contact with the elder.
