"The psychometrist, who needs an object physically connected with the past in order to bring it all into life again around him; and the crystal-gazer who can sometimes direct his less certain astral telescope to some historic scene of long ago, may both derive the greatest enjoyment from the exercise of their respective gifts, even though they may not always understand exactly how their results are produced, and may not have them fully under control under all circumstances. In many cases of the lower manifestation of these powers we find that they are exercised unconsciously; many a crystal-gazer watches scenes from the past without ever realizing that he is in effect psychometrizing the various objects around him as he happens to touch them or stand near them. It would be well for all students to bear in mind that occultism is the apotheosis of common sense, and that every vision that comes to them is not necessarily a picture from the Akashic Records, nor every experience a revelation from on high. It is far better to err on the side of healthy scepticism than that of over-credulity; and it is an admirable rule never to hunt for an occult explanation of anything when a plain and obvious physical one is available. Our duty is to keep our balance always, and never to lose our self-control, but to take a reasonable, common-sense view of whatever may happen to us." Future Time Clairvoyance. In what is known technically as Future Time Clairvoyance, we have the manifestation of the clairvoyant vision in the direction of scenes and events of the future. In this phase of clairvoyance the seer perceives the events and scenes of future time just as if they were present before him at that very moment. This phase of clairvoyance is far rarer and more uncommon than any of the other phases. In fact, it is so seldom met with in its perfection that its manifestation is a matter of greatest interest to those who make a study of the subject. It occasionally occurs in flashes, and can not be produced at will by the ordinary clairvoyant. Unfortunately, its very rarity and uncommonness cause it to be counterfeited and imitated by unprincipled persons. Seeing What Has Not Yet Happened. The student who reasons carefully and logically usually meets with what to him, at least at first, seems to be an unsurmountable obstacle in the way of a rational explanation of Future Time Clairvoyance--when it comes to an understanding of how anyone can expect to see, or can really see, THAT WHICH HAS NEVER HAPPENED, he throws up his hands in despair. But, in this as in all the other phases of clairvoyant phenomena, there is found a reason and cause, although it requires some subtle thinking to find it, and to grasp it even when it is found. Let us see what are the highest teachings on this subject, as announced by the careful thinkers along the lines for many centuries. Simple Prevision.
