So What Is Scientology?
Good question. You can read the official Scientology FAQ answer by clicking here: Scientology FAQs: What is Scientology?.
As for my viewpoint well, Scientology is a very practical philosophy that contains knowledge and techniques you can use in your life to help yourself and others to successfully handle the situations that you meet in life.
So what's an example of one of these techniques? Well here is a technique for handling confusing situations at work and in life: Confusion and the Stable Datum. It's simple and very effective and I personally use it all the time.
A lot more knowledge and techniques are given in the Scientology Handbook. Some of the Handbook is on-line at Scientology Handbook Site and the book itself can be purchased at Amazon: Scientology Handbook.
