How To Move To The Upper World

Question: Is it possible to cross the border to the upper world spontaneously?

Answer: Yes. You can be in a convention, “dive” headfirst into it, and find yourself in the upper world. Like cave explorers who dive into lakes in caves and don’t know to where they will float, so too can you also float and go out to a completely different world.
