“Proclus in Timæus book v., page 330 says, speaking of the BAIE, Spirit:

‘Her seeds are hurled into the realms of generation; and she must purify herself from circumjacent fluctuations of matter. For she contains two-fold powers, one leading to generation the other from generation to true being. The one leads her round the Genesiurgic, the other round the intellectual circle.'” [via]
