It is worth noting that the more members there are in a single community and the more united they are in action, the more perfect is their human form. This is because variety arranged in a heavenly form makes perfection, as explained above in Section 56; and variety occurs where there are many individuals.
Every community in heaven is growing in numbers daily, and the more it grows, the more perfect it becomes. In this way, not only is the community perfected, but heaven in general is perfected as well, since the communities constitute heaven.
Since heaven is perfected by its numerical growth, we can see how mistaken people are who believe that heaven will be closed to prevent overcrowding. Actually, it is just the reverse. It will never be closed, and its ever increasing fullness makes it more perfect. So angels long for nothing more than to have new angel guests arrive there.
The reason each community appears in human likeness when it is seen all together as a unit is that heaven as a whole has this likeness, as may be seen in the preceding chapter; and in the most perfect form, like the form of heaven, there is a likeness of parts and whole, of lesser and greatest. The lesser elements and parts of heaven are the communities of which it consists, each of which is a heaven in lesser form, as may be seen above in Sections 51–58.
The reason for this constant likeness is that in the heavens all the qualities stem from a single love and therefore from a single source. The single love that is the origin of everything good in heaven is love for the Lord from the Lord. This is why all heaven is a likeness of him on the grand scale, every community a likeness on a less grand scale, and every angel in specific. See what has been said on this matter above in Section 58.
