Training is the way to learn the technology of Scientology.
Technology implies use.
There is a gap between knowledge and the application of that knowledge. By becoming trained, a person becomes able to use the truths found in Scientology to actually improve conditions in life. The practice of Scientology emphasizes application. Other religions and practices espouse how one must maintain faith, work out differences or endure with dignity. When a Scientologist enrolls on a Scientology course aimed at providing him the means to better any relationship, he will actually acquire an understanding of the subject, and equally important, the skill to apply it.
