Here is an excellent documentary, made by a monastery, on magic demonstrating demonic influence. Again these magicians are the devil’s marketing campaign for evil. Usually evil hides its self with such sly acumen, that often even the smartest highest IQ men on the planet cannot perceive its presence, or to be more precise smart men are often and easily tricked by evil, so these magic demonstrations are rare instances when demonic influence is on full display. The intended purpose is to sell evil to you, in as appealing way as possible.
