These models, as yet devoid of immortal spirits, are "elementals,"--properly speaking, psychic embryos--which, when their time arrives, die out of the invisible world, and are born into this visible one as human infants, receiving in transitu that divine breath called spirit which completes the perfect man. This class cannot communicate objectively with men.

These are evidently the personified forces of nature in their mutual correlation, the latter being represented by the third class or the "elementals" we have just described.

Further on he shows, on the principle of the Hermetic axiom--of types, and prototypes--that the lower spheres have their subdivisions and classes of beings as well as the upper celestial ones, the former being always subordinate to the higher ones.
