Therefore the angels desire nothing more earnestly than the arrival of new angelic guests.
As heaven is a man in the greatest form, and a society of heaven in a less, so is an angel in the least. For in the most perfect form, which is the form of heaven, there is a likeness of the whole in every part, and of every part in the whole.
