Clairvoyance
The possession of clairvoyant power is a very great privilege and a very great advantage, and if properly and sensibly used it may be a blessing and help to its fortunate holder, just as surely as, if it is misused, it may often be a hindrance and a curse. The principal dangers attendant upon it arise from pride, ignorance, an impurity, and if these be avoided, as they easily may be, nothing but good can come of it.
Pride is the first great danger. The possession of the faculty which, though it is the heritage of the whole human race, is as yet manifested only very occasionally, often causes the ignorant clairvoyant to feel himself (or still more frequently herself) exalted above his fellow, chosen by the Almighty for some mission of worldwide importance, dowered with the discernment that can never err, selected under angelic guidance to be the founder of a new dispensation, and so on. It should be remembered that there are always plenty of sportive and mischievous entities on the other side of the veil who are ready and anxious to foster all such delusions, to reflect and embody all such thoughts, and to fill whatever role of archangel or spirit guide may happen to be suggested to them. Unfortunately it is so easy to persuade the average man that he really is a very fine fellow at bottom, and quite worthy to be the recipient of a special revelation, even though his friends have through blindness or prejudice somehow failed hitherto to appreciate him
Another danger, perhaps the greatest of all because it is the mother of all others, is ignorance. If the clairvoyant knows anything of the history of his subject, if he at all understands the conditions of those other planes into which his vision is penetrating, he cannot of course suppose himself the only person who was ever so highly favored, nor can he feel with self-complacent certainty that it is impossible for him to make a mistake. But when he is, as so many are, in the densest ignorance as to history, conditions and everything else, he is liable in the first place to make all kinds of mistakes as to what he sees, and secondly to be easy prey of all sorts of designing and deceptive entities from the astral plane. He has no criterion by which to judge what he sees, or thinks he sees, no test to apply to his visions or communications, and so he has no sense of relative proportion or the fitness of things, and he magnifies a copy-book maxim into a fragment of divine wisdom, a platitude of the most ordinary type into and angelic message. Then again, for want of common knowledge on scientific subjects he will often utterly misunderstand what his faculties enable him to perceive, and he will, consequently, gravely promulgate the grossest absurdities.
