71. It is worthy of mention that the more there are in one society of heaven, all acting as one, the more perfect is its human form, for variety arranged in a heavenly form is what makes perfection, as was shown above (56) and variety results from plurality. Moreover, every society of heaven increases in number from day to day and as it increases, it becomes more perfect. Thus not only does the society become more perfect, but also heaven in general because it is made up of societies. As heaven gains in perfection by increase of numbers, it is evident how mistaken are those who believe that heaven may be closed by becoming full. For the opposite is true, that it is never closed but is perfected by greater and greater fulness. Therefore, the angels wish for nothing more than to have new angel guests come to them.
