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

For the Gods produce beings in conjunction with themselves, nor is any thing able to subsist, and to receive measure and order external to the Gods, [or beyond their influence.] For all things are perfected through their power, and are arranged and measured by the Gods. Prior therefore to the last genera in beings, the Gods pre-exist, who also adorn these genera, and impart to them life, formation and perfection, and convert them to the good. In a similar manner also, the Gods are prior to the middle and first genera of beings. And all things are bound and rooted in the Gods, and through this cause are preserved. But when any thing apostatizes from, and becomes destitute of the Gods, it entirely departs into non-entity and vanishes, in consequence of being perfectly deprived of those natures by which it was contained.
