When we turn our eye to a beautiful, pure and noble thing, a concept is aroused in us; when we turn our eye to a sordid, ignoble thing then a different concept is aroused. Now when a concept is called forth in the soul through outer impressions there slip into man at the same time these Saturn spirits — the good and the bad. And through all that man by his mere sympathies and antipathies unfolds around himself as environment, as what he hears and sees and smells, he exposes himself to the insinuations of the one or other order of the Saturn-spirits.

So you see how we must picture man to ourselves as quite a complicated being, as an associate of many kinds of worlds, many kinds of beings. One who advances on the path of occult development to ever higher stages of knowledge learns to know these beings in their special nature and thereby becomes independent of them, he is able to view them from an independent standpoint. To take into oneself the truth concerning higher worlds means to become really free, really mature, for we are then aware of the activities and impulses which pulse and flow through our life. Learning to know one’s way means at the same time to become free and independent.
