The "What is Scientology?" web site includes success stories from famous Scientologists. Here's what Lisa Marie says:
L.
Ron Hubbard researched man and has carefully and precisely mapped a route out of the madness, misery and unwanted conditions one can encounter in life. When applied exactly, the technology produces incredible results. Those results are very definite and eternal.
Were it not for Scientology, I would either be completely insane or dead by now. I am forever grateful for the technology of Scientology and to Mr. Hubbard who dedicated his life to helping man and this planet, as well as to the people who have dedicated their lives to helping others through Scientology.
