45:5.3

These Material Sons are the highest type of sex-reproducing beings to be found on the training spheres of the evolving universes. And they are really material; even the Planetary Adams and Eves are plainly visible to the mortal races of the inhabited worlds. These Material Sons are the last and physical link in the chain of personalities extending from divinity and perfection above down to humanity and material existence below. These Sons provide the inhabited worlds with a mutually contactable intermediary between the invisible Planetary Prince and the material creatures of the realms.
