5583. Whence such writing is, was also perceived, that, namely, it is according to the form of heaven, which is of such a nature; about which many things can be said, but not now. - Celestial angels know perfectly what corresponds, as, in what way good proceeds to this or that quarter; and this from ingrafted knowledge, because they are led by the form of heaven. Hence is their writing, and many other things; so that they know what is true without teaching (Jer. 31:33, 34). It is permitted me to relate a certain marvel about a like matter. When angels see any spirit walking below them, then they instantly perceive, from the path in which he is walking, and the bendings of the path hither and thither, of what quality he is, and what he is thinking; whether he is going according to that form in which his thought is: also, from the form they draw their conclusion. Thence it might be manifest to me that the inflections of the writings are according to the form of heaven. To walk according to the heavenly form, and to write according to the heavenly writing, nobody can learn by art. If anyone should learn something of it by art, he would immediately withdraw from heaven, and also would be instantly detected; especially one who is walking; and this, from the set of his face, even when his feet go differently.
