Plotinos: Complete Works, v. 2 In Chronological Order,...

We shall limit ourselves to the above illustration, which may easily be applied to the rest. The sun does not limit itself to warming terrestrial beings. It makes them also participate in its soul, as far as possible; for it possesses a powerful physical soul. Likewise, the other stars, involuntarily, by a kind of irradiation, transmit to inferior beings somewhat of the (natural) power they possess. Although therefore all things (in the universe) form but a single thing of a particular figure, they offer manifold different dispositions; which different figures themselves each have a characteristic power; for each disposition results in appropriate action.
