In short, Tech is knowledge. The more Tech you acquire, the more you understand the religion and the more in tune with God you become. Unlike pretty much every other religion in the world, the followers of Scientology aren’t given the full low down from the word go. They have to invest in Tech. Some people are critical of this religious business model, but I think it makes a lot of sense, particularly in today’s non-stop hectic world. Sometimes you haven’t got time to sit around reading about theology. If you do it by stages, you’ve got a better chance of understanding it all. Like the Open University.
