Everything that exists, in the past, present or future, has a beginning and an end. It comes from consciousness. It exists as long as it is supported by consciousness. And when consciousness shifts, that which previously existed either changes or it disappears. That's the way Life works. That's the way it works in the world at large, and that's the way it works in our own individual lives. Or as Dr. Holmes writes in the Science of Mind, "Creation is always beginning but never ending. The slightest thought of Intelligence sets power in motion through the Law, producing a corresponding thing. Things may come and things may go, but Creation goes on forever.
