134. Since the zones are thus engraved, so to speak, on every angel, and on the whole of heaven as well, therefore an angel knows the location of his home and of his place of abode wherever he goes, unlike a person in the world. A person does not know the location of his home and place of abode from any interior orientation for the reason that he thinks in terms of space, thus in terms of the points of the compass in the natural world, which have nothing in common with the zones in the spiritual world. On the other hand, birds and animals have this knowledge in them, for it is inborn in them to know the location of their homes and places of abode instinctively, as people know from a good deal of empirical observation-evidence that a like phenomenon is found in the spiritual world. For all phenomena that occur in the natural world are effects, and all phenomena that occur in the spiritual world are the causes of those effects. One does not find anything natural that does not have its cause from something spiritual.
