Accordingly we find that persons in various stages of the history of the world have been affected by the influences of witches, sorcerers, and other unprincipled persons. In most cases these so-called witches and sorcerers themselves were under the delusion that they were assisted by the devil or some other supernatural being. They did not realize that they were simply using perfectly natural methods, and employing perfectly natural forces. For that matter, you must remember that magnetism and electricity, in ancient days, were considered as supernatural forces in some way connected with demonic powers. Studying the history of witchcraft, sorcery, black-magic, and the like, you will find that the devotees thereof usually employed some psychometric method. In other cases they would mould little figures of clay, or of wax, in the general shape and appearance of the person whom they wished to affect. It was thought that these little figures were endowed with some supernatural powers or attributes, but of course this was mere superstition. The whole power of these little figures arose from the fact that they aided the imagination of the spell-worker in forming a mental image of the person sought to be influenced; and thus established a strong en rapport condition. Added to this, you must remember that the fear and belief of the public greatly aided the spell-worker and increased his power and influence over these poor persons. I will give you a typical case, taken from an old German book, which thoroughly illustrates the principles involved in cases of this kind. Understand this case, and you will have the secret and working principle of them all. The story is told by an eminent German physician of the last century. He relates that he was consulted by one of his patients, a wealthy farmer living near by. The farmer complained that he was disturbed every night by strange noises which sounded like someone pounding iron. The disturbances occurred between the hours of ten o'clock and midnight, each and every night. The physician asked him if he suspected anyone of causing the strange trouble. The farmer answered that he suspected an old enemy of his, an old village blacksmith living several miles away from his farm. It appears that an old long-standing feud between them had broken out afresh, and that the blacksmith had made threats of employing his "hex" (witchcraft) powers on the old farmer. The blacksmith was reputed to be a sort of "hex" or male-witch, and the farmer believed in his diabolic powers and was very much in fear of them. So you see the ideal condition for psychic receptivity was present.
