Instead of believing anything just wait for the moment you cross over and immediately project yourself to the other side of the galaxy or something. Don't go into the light. Don't go through any doors. Just leave the scene entirely. If you believe you can't get past Jupiter then guess what, you won't get past Jupiter. My suggestion, and what I plan to do, is keep it as simple as possible. Believe nothing I've been told while on this planet. And immediately move my consciousness far away after crossing over. Then I'll have time to figure stuff out.
