Scientology is a religion in its highest meaning, as it helps bring Man to total freedom and truth. The essential tenets of Scientology are these:

You are an immortal spiritual being.

Your experience extends well beyond a single lifetime. And your capabilities are unlimited, even if not presently realized.

Furthermore, Man is basically good. He is seeking to survive. And his survival depends upon himself and his fellows and his attainment of brotherhood with the universe.
