5344. That which was round about it he put in the midst thereof. That this signifies that the things previously in the exterior natural it stored up in the interiors of the interior natural, is evident from the signification of "round about," as being the things outside, thus which were in the exterior natural; and from the signification of the "midst," as being the things within (see n. 1074, 2940, 2973), thus which were in the interior natural. That "in the midst thereof," or of the city, denotes in the interiors of the interior natural, is because the interiors are signified by a "city" (n. 5297, 5342). The interior things of the interior natural are those in it called spiritual, and the spiritual things therein are those which are from the light of heaven, from which light are illumined the things therein which are from the light of the world, and which are properly called natural; in the spiritual things therein are stored up truths adjoined to good. The spiritual things therein are those which correspond to the angelic societies in the second heaven, with which heaven man communicates by means of remains. This is the heaven that is opened when man is being regenerated, and is closed when he does not suffer himself to be regenerated; for remains-or truths and goods stored up in the interiors-are nothing else than correspondences with the societies of that heaven.
