1897. Things corporeal and worldly serve the spirits for a subject or receptacle, as it were, of the idea; natural things, such as the significations of ideas or words, to the angels of the interior heavens; spiritual things to the angels of the more interior heaven; and celestial things to the angels of the inmost heaven. There is, therefore, an ascent through degrees, and through correspondences, such as I believe no mortal understands, on which account a great many things are to be previously learned before one can comprehend even a very general idea of the modes of angelic speech. - 1748, April 25.
