2470. During his lifetime a person is scarcely capable of knowing that he has an interior memory since the interior memory during that time acts almost as one with his exterior memory. In fact the ideas which comprise thought and belong to the interior memory flow into the contents of the exterior memory as their own vessels and are joined together with them there. It is similar to when angels and spirits speak to man; at such times their ideas by means of which they speak to one another flow into the expressions of man's language. Their ideas join themselves to those expressions in such a way that they know no other than that they themselves are speaking in the man's own native tongue, when in fact the ideas are theirs but the expressions into which these flow are the man's. This is a matter I have frequently talked about to spirits.
