'A whale,' as in Jeremiah 51:34, signifies people who possess the universal aspects of the knowledges of faith, as known, and apply them to evil purposes. 'Whales,' or 'great fishes,' are sometimes mentioned in the prophets, and are used to signify the universal aspects of knowledges

116. THE SUN IN HEAVEN.

In heaven neither the sun of the world, nor anything from that sun, is seen, because it is wholly natural. For nature has its beginning from that sun, and whatever is produced by means of it is called natural. But the spiritual, to which heaven belongs, is above nature and wholly distinct from what is natural; and there is no communication between the two except by correspondences. What the distinction between them is may be understood from what has been already said about degrees (38), and what the communication is from what has been said in the two preceding chapters about correspondences.
