The Six Books of Proclus on the Theology of Plato, Volume 2

[For if it is a divine soul] it is necessary that it should be allotted an order [which is the leader or generator[318]] of all things, and which has a primary rank among souls. For in all beings that which is divine, is the leader of wholes. It is likewise requisite that every divine soul should neither alone preside over such souls as perpetually follow the Gods, nor over those alone that are sometimes their attendants. For if any divine soul should alone preside over those that sometimes follow the Gods, how can there be a contact between these and a divine soul, since they are entirely different from it, and neither proximately participate of intellect, nor much less of the Gods. But if it only presides over those that always follow the Gods, how is it that the series proceeds as far as to these [alone]? For thus intellectual natures will be the last, and will be unprolific, and unadapted to perfect and elevate. It is necessary, therefore, that such souls as follow the Gods, and energize according to intellect, and which are elevated to intellects more partial than divine intellects, should be primarily suspended from a divine soul. But it is necessary that partial souls, and which through those that are divine as media, participate of intellect and a divine life, should be suspended from a divine soul in the second place. For through those which always participate of a more excellent condition, those that sometimes only participate of it, are perfected.

And again, it is necessary that about every divine soul, there should be a greater number of those that only sometimes follow, than of those that always attend on the Gods. For the power of the monad always proceeds into multitude, according to diminution; being deficient indeed in power, but redundant in multitude. Since every soul also of those that always follow the Gods, is the leader of a greater multitude of partial souls, imitating in this a divine soul; and elevates a greater number of souls to the primary monad of the whole series. Every divine soul, therefore, is the leader of many souls that always follow the Gods, but presides over a still greater number of those that sometimes only receive this order.
