"Your attention is hereby called to a very important psychic principle involved in the manifestation of that class of phenomena in which is embraced the cases of witchcraft, sorcery, etc., with which the pages of history are filled. It is a well established fact that by denying the psychic power over you exerted by any person whatsoever, you practically neutralize the psychic power of such person, at least so far as its effect upon and power over yourself is concerned. The stronger and more positive is your mental attitude of immunity to such power, and your assertion and affirmation of that immunity, the greater is your own power of psychic resistance, and the less does his possible power over you become. The average person, not knowing this, is more or less passive to psychic influences of other persons, and may be affected by them to a greater or less extent, the degree depending upon the psychic development of the person seeking to influence him. The Negative Pole. "At the extreme negative pole of susceptibility we find persons who believe firmly that other persons have psychic power over them, and who are consequently more or less afraid of such persons and of their influence. This belief and fear operates in the direction of making such persons peculiarly sensitive and impressionable to such influence, and thus easily affected by psychic induction. This is the reason that the so-called witches and sorcerers and others of evil repute have been often able to acquire such a power over their victims, and to cause them so much trouble. The secret is that THE VICTIMS BELIEVED IN THE POWER OF THE OTHER PERSONS, AND FEARED THEIR POWER. The greater the belief in, and fear of, the power of the other persons, the greater the susceptibility to their influence; the greater the disbelief in such power, and the firm belief in one's own power of immunity and that of neutralizing the effect of the psychic influence of other persons, the less is one's degree of susceptibility, and the greater is one's degree of immunity and power. This is the rule in the case--keep it in mind! Voodooism Explained.
