It is he who, being one only, rules over every germ (cause), over all forms, and over all germs; it is he who, in the beginning, bears in his thoughts the wise son, the fiery, whom he wishes to look on while he is born.

In plain words: The one God rules over every cause and every form. In the beginning he held in his thoughts the wise, fiery son, and he wished to watch him as he was born.
