Our five senses can access only a tiny frequency range, like a radio tuned to one station. In the space you are occupying now are all the radio and television stations broadcasting to your area. You can't see them and they can't see each other because they are on different wavelengths. But move your radio dial and suddenly there they are, one after the other. It is the same with the reality we experience here as "life". What we call the "world" and the "universe" is only one frequency range in an infinite number sharing the same space.
