By way of illustration, I should like to offer one instance of the way things look to angels because of correspondences. To angels who are focused on intelligence there appear gardens and parks full of all kinds of trees and flowers. The trees there are laid out in the loveliest designs, joined into vaulted arches offering spaces for entrance, and with promenades around them. All this is so beautiful as to defy description. People who are focused on intelligence stroll there picking the flowers and weaving garlands to grace babies with. There are kinds of tree and flower there never seen, not even possible, in our world. In the trees, too, there are fruits in keeping with the quality of the love these intelligent angels are absorbed in. They see such things because a garden and a park, and the fruit trees and flowers, correspond to intelligence and wisdom.
It is known on earth that things like this exist in the heavens, but it is known only to people who are engaged in what is good and who have not extinguished heaven’s light within themselves by natural light and its deceptiveness. When the subject is heaven, people actually think and say that things are there that ear has never heard, nor eye seen.
