As soon as children are reawakened (which happens immediately after their death), they are taken to heaven and given to female angels who had loved children tenderly during their physical lives and had loved God as well. Since in this world they had loved all children with a kind of maternal tenderness, they accept these new ones as their own, and the children love them as their mothers as though this were inborn in them. Each such angel has as many children as her spiritual maternal nature wants.
This heaven can be seen in the forward part of the forehead, directly on the line or radius along which angels look at the Lord. The reason for this location is that children are under the direct care of the Lord. Into them flows the heaven of innocence, which is the third heaven.
Children have different natures. Some have the nature of spiritual angels, some the nature of heavenly angels. The children of a heavenly nature appear on the right in heaven, and the ones of a spiritual nature on the left. All the children in the universal human that is heaven are in the province of the eyes, with the ones of a spiritual nature in the province of the left eye and the ones of a heavenly nature in the province of the right eye. This is because to angels of the spiritual kingdom, the Lord appears to be in front of the left eye and to angels of the heavenly kingdom he appears to be in front of the right eye (see §118 above). Since children are in the province of the eye in the universal human or heaven, we can see that they are under the Lord’s direct view and care.
We need to explain briefly how children are brought up in heaven. They learn to talk from their nurse. Their first speech is only the sound of their affection, which gradually becomes more articulated to the extent that the concepts they are thinking enter in, since such concepts arising from affections make up the whole angelic language, as may be seen in Sections 234–245.
The first things instilled into these affections (which all stem from their innocence) are the kinds of thing they see with their eyes that particularly delight them; and since these are from a spiritual origin, aspects of heaven flow into them that serve to open their deeper natures. In this way they become more perfect every day. Once this first age has been completed, they are taken to another heaven where they are taught by instructors, and so on.
