Marsilio Ficino’s Platonic Theology, Volume I

5Soul nourishes the body and digests many things within it at once, without anxiety or labor. So God, through his being—which is the simplest center of things, from which all else extends like lines—sets in motion with the easiest nod whatever depends upon him. This is the difference between the first agent and all other agents: the first agent is said to act through being in such a way that it acts through pure being, while the others act through being in the sense of some natural, or, so to speak, essential power. Thus operation proceeding from deliberation is preceded by operation performed through essential power, and this in turn by operation proceeding from pure being. And just as what is done through power is easier than what is done through deliberation, so what is accomplished through pure being is easier than what is done through power.
