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

For that by which each thing is infinite, by this also it exists uncircumscribed. But every thing which is in [true] beings, is bounded by itself, and by all the things prior to it. It remains therefore, that the infinite which is in [true] beings, is infinite to subordinate natures alone, above which it is so expanded in power, as to be incomprehensible by all of them. For in whatever manner they may extend themselves towards this infinite, yet it has something[247] entirely exempt from them. And though all things enter into it, yet it has something occult, and incomprehensible by secondary natures. Though likewise it evolves the powers which it contains, yet it possesses something on account of its union insurmountable, contracted, and surpassing the evolution of beings. Since however, it contains and bounds itself, it will not be infinite to itself, nor much less to the natures situated above it, since it has a portion of the infinity which is in them. For the powers of more total natures are more infinite, in consequence of being more total, and having an arrangement nearer to the first infinity.
