Occultists have elaborated a technical theory to account for the phenomena of Psychometry, or rather to account for the action of the "connecting link" of the physical object employed to establish the connection between clairvoyant and distant object, person, or scene. But we do not think it advisable to enter into a discussion of these elaborate, technical theories, which are apt to confuse the beginner, and to distract his attention from the important facts of the case. We think it is sufficient to say that the "connecting link," or physical object, seems to carry along with it, in its inner substance or nature, the vibrations of its past environment; and that the clairvoyant, coming into receptive contact with such vibrations, is enabled with comparative ease to follow up the psychic "scent" until he establishes clairvoyant en rapport connection with the distant object, person, or scene associated with the physical object. When it is remembered that the physical "scent" of anything is merely a matter of the detection of certain vibrations, the illustration is seen to be not so very far out of the way after all. Magnetic Affinity. A somewhat celebrated investigator of psychic and occult phenomena has said concerning this phases of Clairvoyance: "The untrained clairvoyant usually cannot find any particular astral picture when it is wanted, without some special link to put him en rapport with the subject required. Psychometry is an instance in point. It seems as though there were a sort of magnetic attachment or affinity between any particle of matter and the record which contains its history--an affinity which enables it to act as a kind of conductor between that record and the faculties of anyone who can read it. For instance, I once brought from Stonehenge a tiny fragment of stone, not larger than a pin's head, and on putting this into an envelope and handing it to a psychometrist who had no idea what it was, she at once began to describe that wonderful ruin and the desolate country surrounding it, and then went on to picture vividly what were evidently scenes from its early history, showing that the infinitesimal fragment had been sufficient to put her into communication with the records connected with the spot from which it came. The scenes through which we pass in the course of our life seem to act in the same way upon the cells of our brain as did the history of Stonehenge upon that particle of stone. They establish a connection with those cells by means of which our mind is put en rapport with that particular portion of the records, and so we 'remember' what we have seen." Distant En Rapport.
