Answer: “Outside of us” means “outside” the point of our desire within which I perceive this world, myself, and everybody else. Besides this point, there is nothing since the Creator created only a single point. Everything that we perceive (the worlds and what fills them) is the sensation of that point itself.
There is only one tiny, black point against the white Light of Infinity.
