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

Every God, from that order from which he began to unfold himself into light, proceeds through all secondary natures, always indeed multiplying and dividing the communications of himself, but preserving the peculiarity of his own hypostasis.

For progressions being effected through diminution, first natures are every where after a manner multiplied into the decrements of secondary natures. But these proceeding according to a similitude to their producing causes receive their orderly distribution, so that the whole of that which proceeds is after a manner the same with, and different from, that which abides; through its diminution indeed, appearing to be different, but through continuity with its cause, not departing from sameness with it. But such as that which abides is among first, such is that which proceeds, among secondary natures; and thus an indissoluble communion of the series is preserved. Each of the Gods, therefore, is unfolded into light appropriately, in the orders in which he makes his evolution. But he proceeds from thence, as far as to the last of things, through the generative power of first natures. He is always, however, multiplied according to a progression from unity into multitude. But he preserves sameness in the progression, through the similitude of the things that proceed to the leader and primary cause of each series.
