But this, however, is but an illustration of the correspondence on the ordinary physical plane of certain things on a higher plane of Nature. Past Time Clairvoyance is not dependent upon light-waves, or any other of the lesser phases of vibratory activity. Instead, it depends entirely upon the phenomena and facts of a higher plane of Nature--a plane which occultists have called the Akashic Plane. Some occultists prefer the general term, "the Astral Plane," but the former term is a closer and more definite one. The Akashic Plane, as known to occultists, contains the impressions or "records" of all events that have happened on the earth plane during the present cycle of earth manifestation. The very subtle and tenuous substance of the Akashic Plane--the term "etheric" may best describe the nature of this substance--contains traces and impressions of all the happenings of the past of this earth; and such impressions may be read and seen by the clairvoyant who has developed sufficiently high powers of vision. These Akashic Records have well been called "the substantial memory of the earth." Upon the subtle etheric substance of the Akashic Plane are registered the records of every event, thing, object, happening, or activity of the earth which has existed or been manifested from the very beginning of the present cycle of the earth's existence. These records will, it is claimed, persist until the final ending of the present earth cycle. The Akashic Records. The clairvoyant whose powers of Past Time Clairvoyance have been developed sufficiently, and who has mastered the art of concentration of his psychic attention, manages to come into more or less perfect en rapport condition contact with these Akashic Records, and is thus enabled to read from them what he sees there. To him it actually seems as if he were seeing the actions of things in present existence, and many excellent clairvoyants are ignorant of the existence of the Akashic Records, though they habitually read the contents thereof; these clairvoyants know simply that they "see" these past happenings--they have not the faintest conception of how they are able to see them. This is no more strange than would be the case of a man who witnessed a moving picture for the first time, and who was ignorant of the mechanism involved in the showing of the picture, the existence of the film, etc.,--such a man would simply know that he "saw" the things, and he might even believe that he was gazing upon an actual scene in real life.
