In plain words
The Self is one, dwelling in all beings, and all beings dwell in it—just as clouds and elements move within open space. Pervading everything like the sky, luminous and pure, it is declared to be supreme.
Close to the Sanskrit
The self is one in all beings, and those are in it, just as in space; like the sky it pervaded all; bright and luminous it is considered.
