This verse is poetry and philosophy braided together. Krishna says: that Brahman has hands and feet on every side, eyes and heads and faces on every side, ears on every side. It pervades everything in this world and remains.
This does not mean Brahman has a literal body. Wherever a hand is working, Brahman's power is at work. Wherever an eye is seeing, Brahman's awareness is present. It is not confined to one location. It is everywhere at once.
