2470. Man, while living in the body, can scarcely be aware that he has an interior memory, because the interior memory then acts almost as one with his exterior memory; for the ideas of thought of the interior memory flow into the things in the exterior memory as into their vessels, and the two are there conjoined together. It is as when angels and spirits are speaking to a man; for then the ideas of the former, by which they converse with each other, flow into the words of the man's language, and so conjoin themselves with them that the spirits know no otherwise than that they are speaking the man's own language; when yet the ideas are theirs, and the words into which they flow are the man's; on which subject I have often spoken with spirits.
