Guarding Against Fraudulent Spirits. One writer says: "While most mediums seek for some guide or control of prominence, it must not be always taken for granted that the controlling spirit during a seance is always just what he claims to be. For instance, a spirit control might give his name as Henry Clay, and he might deliver a spirited talk or oration, which, however, would be reeking with grammatical errors. Even though he insist that he is Henry Clay, our reason will tell us that he is not what he pretends to be. The change which we call death cannot lead all spirits to reform, and there are many who, as in earth life, are unworthy of our association, and should be gotten rid of as soon as they appear. When these fraudulent spirits appear, the atmosphere of the circle should be made very sacred and high in character. Evil spirits, and those of low characters, cannot endure the presence of elevated and high thoughts, and by the holding of thoughts of this character the circle can soon rid itself for good of these troublesome entities--and it should do so without fail." Spirit Jokers. Another writer says, on this point: "That there are spirits who sometimes impersonate, and seek to pass themselves off as friends of the sitters, cannot be denied; in fact, we have had personal proof of the same on several occasions. But these troublesome and vexatious visitors invariably get 'bowled out' if the investigators are observant and careful. In fact, such entities are neither as numerous, or as evilly disposed, as many persons imagine them to be. There are spirits who 'play up to' the weaknesses and flatter the vanity of those to whom they communicate. And it is equally true that there are spirits who give glowing assurances of the good things that they will perform by-and-by, and profess to be some of the 'great ones' of the past, is equally true. It is a well-known saying that 'people love a lord,' and this amiable weakness is fully realized by the jokers on the other side--but the fault does not wholly rest with them! Their too confiding and credulous mediums are too often in the main responsible for their own mystification and misleading. They are often so anxious to be guided by some 'eminent' person who will be to them an 'authority,' that they practically invite spirit pretenders to fool them to the top of their bent. This does not apply to all cases of real or supposed deception, but it does cover a large proportion of such experiences. In many instances there is an element of self-deception--or auto-suggestion--and the 'wish becomes father to the thought,' and the sensitive medium's unrestrained imaginative powers do the rest."
