If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Scientology: The Fundamentals of Thought.
This book really helped me with satisfying my hunger for the true facts of life! The conditions of life and principals of existence. Very simple ideas that are very far-reaching and instantly applicable.
I also recommend Advanced Procedures and Axioms and The Handbook for Preclears. These are excellent for clearing up false information and demystifying the basics of life.
