"When you go into the other worlds, when you go into the luminous dimensions, it's very different than here. You really have to have your act wired. You have to be very strong. Your mind has to be in the right shape. Otherwise, when you get out there, what you will see will drive you mad."

If you go too far, it'll blow your mind. I mean it's strong out there. If you go out too far beyond the bounds of attention, there are things in the universe, in the universes of mind, in the inner worlds, it's best sometimes not to deal with unless you're very, very far along.
