It is at the command of him who always covers this world, the knower, the time of time, who assumes qualities and all knowledge, it is at his command that this work (creation) unfolds itself, which is called earth, water, fire, air, and ether;

In plain words: God always surrounds this world. He knows everything and is the master even of time. At his command creation unfolds as earth, water, fire, air and space.
