In plain words
Or alternatively, because all aspirations rest in him. 'Mṛta' is death; one whose form is untouched by mortality is Amritavapu, the immortal-bodied. Because he cognizes everything, he is Sarvajna, the Omniscient—corroborated by the Upanishadic text: 'He who is all-knowing and all-perceiving.' And in accordance with the Lord's declaration: 'Having eyes, heads, and faces in every direction,' he is Sarvatomukha, facing all ways.

Or because desires belong to him. Death is destruction; one whose body is free from that is Amritavapu. Because he knows everything, Sarvajna. As the Vedic text says: 'Who is all-knowing and all-knowing.' According to the Lord's statement: 'Having eyes, heads, and faces everywhere', Sarvatomukha.
