More about the immortal thetan, who is the "you" in your body. You now not only have to "clear" your earthly body, you have to "clear" you as a thetan. What a coincidence, that costs money. BUT, once you are a cleared thetan, you can MOVE AND CREATE THINGS WITH YOUR MIND.
It's a lot like The Matrix - this world is just an illusion that we all agree on, and that agreement gives it 'reality'. Once you realize that this is the case, you can change it, since thetans create their own universes.
There's a lot about "mocking up" objects in the process of this 'therapy', which means imagining them. Imagined things, apparently, are just as real as real things. So that would make this religion/science just as real as, say, The Teletubbies.
