The Guardian of the Threshold: Scene 6

Capesius: What lives here in its own reality Souls, versed in spirit-ways, can grasp with ease; Each thing explains itself through something else. The whole may stand revealed in light, when part Seen by itself, may often still seem dark. But when a spirit-essence doth unite With earthly nature to create some work, The soul begins to lose her grasp of things. And not alone a part, but e'en the whole Is oft concealed from her by darkness deep. Why words which come in Benedictus' book And which were written for men's souls on Earth, Should echo here, within a place like this, That is the problem which doth offer here.
