Since the whole heaven resembles one man and is a Divine spiritual man in the greatest form in its very likeness, so heaven, like a man, is arranged into members and parts which are similarly named.
Moreover, angels know in what member this or that society is. This society, they say, is in the head or a certain province of the head, another in the breast or a certain province of the breast, that,
in the loins or a certain province of the loins, and so forth. In general, the highest or third heaven forms the head down to the neck, the middle or second heaven forms the breast down to the loins
and knees, the lowest or first heaven forms the feet down to the soles and also the arms down to the fingers, for the arms and hands are the ultimates of a man, although at the sides. This again makes
it evident why there are three heavens.
