Meditate upon the ray of light that pierces through a window on a sunny day-- and imagine how that ray exists engulfed within its source, the sun. So too, is the cosmos a nothingness absorbed within its Source, the Infinite Light.
Imagine the entire universe as a stream of conscious thought, and imagine how a single thought exists in its place of birth, a place before words, before things, where there is only One.
We created beings cannot perceive the Source with our flesh eyes, and so we see a world. But to the Source there is no being, no entity, only the Infinite Light.
