Brunetto Latini

By these four elements he is perpetually surrounded, only he does not know what they are inwardly. He cannot see it with outer organs of sense. He must first get out of the sense-organs—albeit, get out of them from within. He must leave them again, as though by a gateway. He must get out, through his eye or his ear. So he slips through—through the eye, through the ear—and comes into the region of the elements. And in the region of the elements he learns to know all the spiritual beings who are living there—the manifold Nature-spirits, and Beings who belong to the Hierarchies nearest to man.
