This idea is that consciousness is a prerequisite to any universe. I say this because there is not one atom in the universe that exists outside of your mind, independently of your mind. This can be proved by the fact that our minds are capable of misunderstanding, miscalculating, dreaming and hallucinating. yet that same mind is the one in which your universe exists. The best that can be said of the universe is therefore that it is your mind's universe. It cannot be said to exist independently of the mind. Therefore, the world is within your consciousness, not the other way around.
