In a Nutshell
The Church of Scientology is a vicious and dangerous cult that masquerades as a religion. Its purpose is to make money. It practices a variety of mind-control techniques on people lured into its midst to gain control over their money and their lives. Its aim is to take from them every penny that they have and can ever borrow and to also enslave them to further its wicked ends.
It was started in the 1950s by a science fiction writer named L. Ron Hubbard in fulfilment to his declared aim to start a religion to make money. It is an offshoot to a method of psychotherapy he concocted from various sources which he named "Dianetics". Dianetics is a form of regression therapy. It was then further expanded to appear more like a religion in order to enjoy tax benefits. He called it "Scientology".
Scientology is a confused concoction of crackpot, dangerously applied psychotherapy, oversimplified, idiotic and inapplicable rules and ideas and science-fiction drivel that is presented to its members (at the "advanced" levels) as profound spiritual truth.
The Harm it Does to a PersonThe results of applying their crackpot psychotherapy (called "auditing") is to weaken the mind. The mind goes from a rational state to an irrational one as the delusional contents of the subconscious mind are brought to the surface and are assumed to be valid. It also makes a person more susceptible to suggestion since it submerges the critical thinking faculties of the mind into a partial subconscious state. It results in a permanent light hypnotic trance and so from thenceforth that person can be more easily controlled. The person will, to a much greater extent, believe and do whatever they are told. And of course this is used to the full in persuading them to hand over further money and dedicating themselves further to the cult.
The results of applying their oversimplified and inapplicable rules in life is to lose the ability to think rationally and logically. A person loses the ability to think for themselves and so they lose the ability to challenge incorrect ideas. This makes them easier to control. It also isolates and alienates the person from society so that they withdraw from normal society and into their "Scientology" society. This further increases their susceptibility to the influence of their group. They end up being afraid of society, believing all society to be controlled by a group of drug companies, psychiatrists and financiers all of whom report to more remote masters. In other words they are in a state of mass paranoia. They therefore avoid reading newspapers and the like since they fear it will disturb their safe Scientology world. It is a downward spiral into madness.
The science fiction content of Scientology is revealed to them after they have reached the state they call "Clear", meaning freed from the aberrations of the mind. However, perhaps "brainwashed" would be a more applicable word to describe the mental state of someone who has survived the near entire delusional contents of their subconscious mind brought to the surface and presented to them as "truth". On the "advanced" levels (called OT levels) above the state of "Clear" they encounter the story of Xenu. Xenu was supposed to have gathered up all the overpopulation in this sector of the galaxy, brought them to Earth and then exterminated them using hydrogen bombs. The souls of these murdered people are then supposed to infest the body of everyone. They are called "body thetans". On the advanced levels of Scientology a person "audits out" these body thetans telepathically by getting them to re-experience their being exterminated by hydrogen bombs. So people on these levels assume all their bad thoughts and faulty memories are due to these body thetans infesting every part of their body and influencing them mentally. Many Scientologists go raving mad at this point if they have not done so already.
