Scientology Aims:
A civilization without insanity, without criminals and without war, where the able can prosper and honest beings can have rights, and where man is free to rise to greater heights, are the aims of Scientology. ? L. Ron Hubbard
Scientology is an applied religious philosophy.
The fastest growing religious movement on earth, Scientology has become a firmly established and active force for positive change in the world in less than half a century. In a word, Scientology works.
And this is why millions of people the world over use its principles in their daily lives, why a growing number of people find such relevance in Scientology for themselves, their families, their organizations, their nations and this entire civilization.
There are more than 3,200 churches, missions and groups in 154 countries.
A maxim in Scientology is that only those things which one finds true for himself are true. In Scientology one learns to think for himself ? it is a voyage of self-discovery.
