71. 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 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.
