Past-time clairvoyance is frequently induced by means of psychometry, in which the clairvoyant is able to have "the loose end" to unwind the ball of time. But, still, in some cases the clairvoyant is able to get en rapport with the astral records of past-time by the ordinary methods of meditation, etc. The main obstacle in the last mentioned case is the difficulty of coming in contact with the exact period of past-time sought for--in psychometry, the vibrations of the "associated object" supplies the missing-link. Lacking the "associated object," the clairvoyant may obtain the link by bringing into the imagination some associated scene of that time--something else that happened about the same time. All that is needed is to get hold of something associated in space or in time with the sought for scene. All that is needed is the "loose end" of association. Sometimes the clairvoyant senses some past-time experience, the place and time of which is unknown to him. In such cases, it is necessary for him to get hold of some "loose end" by which he may work out the solution. For instance, the picture of a certain building or personage, or historical happening, may give the key to the mystery. In very high forms of past-time clairvoyance, the clairvoyant is able not only to perceive the actual happenings of the past, but also to actually sense the thought and feelings of the actors therein--for these, too, are recorded on the astral plane. In other cases, the clairvoyant person is able to picture scenes and happenings relating to his past incarnations, even though he is not able to sense other past-time events and scenes. But, here again, many good past-time clairvoyants are not able to catch these glimpses of their own past lives, though able to perceive those of other persons. All these variations are due to certain technical differences into which I cannot go into detail at this place. Again some persons are able to perceive events that have happened to persons present before them, but are not able to contact past-time events in the ordinary way. There are a thousand-and-one variations in clairvoyant work. Only the highly advanced occultist is master of all of them. But, still every one may develop himself or herself, from humble beginnings.
