The Scientology is not the typical “Judgment day” cult. It has many followers, and it is among the most famous cults in the world. Their preachers tend to use brainwashing to manipulate their followers. This cult’s fundamental principle is the idea of rejecting all “negative” emotions and memories and bringing out humans’ “full potential” to the surface during the intense therapy. It is said that it is based on science and research facts. The rumor is that this organization tends to kill critics and members who try to get out making this group very mysterious. It has some celebrity followers like Tom Cruise and Priscilla Presley.
