Ouija boards are a form of divination, hence they bring demons on the user. Just having one in your house will bring demons. In demonology they use particuliar rituals and symbols as they try and control spirits, the ouija on the other hand most satanists dont even want to mess with as there is no control. I can assure you the ouija will be a snare on your life. Demons will actually move the lense thing when you call on them, what most dont realize is the demon is with them long after the experience. Repenting sins to Jesus Christ is the only way to remove demons. Demons work on deceit and making you think they arent there, while destroying your life at the same time
