3633. All spirits and angels appear to themselves as men; of such a face and such a body, with organs and members; and this for the reason that their inmost conspires to such a form; just as the primitive of man, which is from the soul of the parent, endeavors toward the formation of the whole man in the ovum and the womb, although this primitive is not in the form of the body, but in another most perfect form known to the Lord alone; and inasmuch as the inmost with everyone in like manner conspires and endeavors toward such a form, therefore all there appear as men. Moreover the universal heaven is such that everyone is as it were the center of all, for he is the center of influxes from all through the heavenly form; and hence an image of heaven results in everyone, and makes him like unto itself, thus a man; for such as the general is, such is a part of the general, inasmuch as the parts must be like their general, in order that they may be of it.
