In plain words

In the beginning there was nothing at all here. This was covered over by Death, by hunger; for hunger is death. He formed the wish, "Let me have a self." He moved about worshipping; and from his worshipping the waters were born. "Because while I worshipped there was joy for me" — that is the arka-hood of the arka. Joy indeed comes to him who knows thus the arka-hood of the arka.
