I have also been shown how all these things are instilled using delightful and charming means that are suited to their natures. I have in fact been allowed to see children clothed most becomingly, with garlands of flowers around their chests glowing with the most charming and heavenly colors, and similar ones around their slender arms. Once I was even allowed to see some children with their nurses, in the company of some young women in a paradisal garden—not a garden of trees, but one with vaulted arches of something like laurels making the most intricate doorways with paths offering access inward—and the children themselves dressed with like beauty. When they entered, the flowers over the entrance radiated the most joyous light imaginable. This enabled me to gather what their delights were like and how they were led into the blessings of innocence and thoughtfulness by things charming and delightful, with the Lord constantly instilling blessings by means of these charming and delightful gifts.
By a means of communication that is common in the other life, I have been shown what children’s concepts are like when they are looking at various objects. It is as though everything were alive; so in the smallest concepts of their thought there is an inherent life. I gathered that children on earth have concepts that are much the same when they are involved in their play, for they do not yet have the kind of reflective thought that grownups have about what is inanimate. 339 I mentioned earlier that children have either a heavenly or a spiritual nature. You can tell the ones of a heavenly nature from the ones of a spiritual nature very clearly. The former think and talk and act more gently, so that hardly anything is perceptible but something flowing from a love of what is good, a love for the Lord and for other children. The latter do not think and talk and act so gently. Instead, there is something like fluttering wings that shows in them in small ways. Then too, it can be seen in their annoyance, as well as in other things.
