आवर्तनो निवृत्तात्मा संवृतः संप्रमर्दनः ।
In plain words
He turns the wheel of birth and death. His own self has turned away from it. He is the hidden one, and the one who grinds everything to dust.
Close to the Sanskrit
The turner-round; he whose self has turned back; the covered one; the thorough crusher.
