। ॥ ३९० ॥
In plain words
It is inside you and outside you both. It is what's ahead and what's behind. It is south and it is north. It is above and it is below. Wherever you point, that is where it already is.
Close to the Sanskrit
It is itself within, and itself also without; itself in front, itself alone behind; itself indeed to the south, itself also to the north; likewise itself above, itself also below.
