We bow unto that Prime State of Vishnu which is pure cognition, which is constant, causeless, undeteriorating and unspent; and which is the unmanifested and unmodified. We bow down unto that Prime and ever pure state of Vishnu, which is not gross and yet not subtile; which cannot be differentiated. We bow unto that undeteriorating one who is the Supreme Brahmā,—and in one of whose Ayuta of Ayuta portions is this cosmic energy established.

In plain words: Brahma bows to Vishnu's highest state, which is pure awareness. It is eternal, never decays and has no cause. It is neither large nor tiny and cannot be divided. All the energy of the universe rests in just a tiny fraction of him.
