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 Dianetics: The Modern Science of Mental Health.
This book really helped me with ....Well, when I read this book twenty-six years ago I told myself, "If only 10% of what this guy says is true -- I've found what I'm looking for." Since that time I've become skilled in Dianetics and Scientology as a professional auditor and have audited others thousands of hours. Additionally, I've received hundreds of hours of auditing myself. I can personally attest what "this guy said" is 100% true.
