Selection from Arcana Coelestia ~ Emanuel Swedenborg
Words in the original language signify things is because "words," in the internal sense signify truths of doctrine; and therefore all Divine truth in general is called the "Word," and the Lord Himself, from whom comes all Divine truth, is in the supreme sense the "Word". And because nothing that exists in the universe is anything, that is, is a real thing, unless it is from Divine good by Divine truth, therefore "words" in the Hebrew language mean things also. That nothing in the universe is anything, that is, a real thing, unless it is from Divine good by Divine truth, that is, by the "Word," is plain in John:In the beginning was the Word, and the Word was with God, and God was the Word. All things were made by Him; and without Him was not anything made that was made. (John 1:1, 3)The interior significations of expressions, for the most part, originate in the interior man, which is among spirits and angels; for every man as to his spirit, or as to that very man which lives after the decease of the body, is in company with angels and spirits, although the external man is not aware of this. Because he is in company with them, he is also with them in the universal language, and thus in the origins of words. Hence there are imparted to words many significations which in the external form appear out of agreement, although in the internal form they are entirely in agreement. It is the same in a host of cases, as that the understanding is called the inward "sight," light being attributed to it; that attention and obedience are called "hearing" and "hearkening;" that the perception of a thing is called "smelling;" and so forth.
