What correspondences are, and what representations are, may be seen from what has been stated and shown already; namely that correspondences exist between things belonging to the light of heaven and those belonging to the light of the world, while representations consist of things belonging to the light of heaven which manifest themselves within those belonging to the light of the world, 3225. But what the light of heaven is, and the nature of it, cannot be known so easily by man because he dwells within the things that belong to the light of the world. And to the extent he dwells within these the things that exist within the light of heaven are seen by him as darkness and as nothing at all. These two, the light of heaven and the light of the world, are what form the whole of man's intelligence, when life is flowing in.

[2] In man mental images are nothing else than the forms and shapes of such things as he has been taking in with his physical sight - forms and shapes wonderfully diverse or, as I will call it, modified. His interior mental images or thought however are nothing else than the forms and shapes of such things as he has absorbed with his mental sight - forms and shapes even more wonderfully diverse or, as again I will call it, modified. Things which come into being in this way are not in themselves animate but are made so from the influx of life from the Lord.
