—something the celestial body could not achieve in its individual number; its perpetuity was therefore preserved through species and succession. Thus motion came to safeguard whatever measure of that perfection could still be attained. The source of this motion is the yearning to resemble the Supreme Good by remaining, as far as possible, in the highest state of perfection. The beginning of that yearning lies in what the body apprehends of Him, together with the conditions that follow from this apprehension and the superior proportions it derives, through which it mirrors the First in His role as the Bestower of blessings. The aim is not those conditions and proportions themselves, so that motion would occur for their sake; rather, the aim is to imitate the First to the utmost degree—maintaining the most perfect state in its own essence and in all that accompanies it—insofar as this is an imitation of the First, not insofar as things merely issue from it.
