All the communities communicate with each other, but not through open interaction. Actually, not many individuals leave their own community to go to another, because leaving their community is like leaving themselves or their life and crossing over into another that does not suit them. Rather, they all communicate by the outreach of the auras that emanate from the life of every individual. An aura of life is an aura of affections based in love and faith. This reaches out far and wide into surrounding communities, farther and wider as the affections are deeper and more perfect. Angels possess intelligence and wisdom in proportion to this outreach. The ones who are in the most inward heaven and therefore at the center have an outreach into all of heaven, so that there is a communication of everyone in heaven with each individual and of each individual with everyone. We will have more to say about this outreach below, though, when we discuss the heavenly form in which angelic communities are arranged (and also when we discuss the wisdom and intelligence of angels), for all the outreach of affections and thoughts follows this form.
We have noted above that there are larger and smaller communities in the heavens. The larger ones consist of tens of thousands of individuals, the smaller of some thousands, and the smallest of hundreds. There are even people who live alone, house by house, so to speak, and family by family. Even though they live apart, they are still arranged in the same pattern as those who live in communities, with the wiser of them in the center and the simpler at the periphery. They are very closely under the Lord’s guidance, and are the best of angels.
