7130. And the people scattered into all the land of Egypt. That this signifies that they overspread the natural mind on every side, is evident from the signification of “scattering themselves,” as being to overspread; and from the signification of the “land of Egypt,” as being the natural mind (n. 5276, 5278, 5280, 5288, 5301). There are two minds in man; one is the natural, and the other the rational mind; the natural mind is the mind of the external man, but the rational mind is the mind of the internal man. The things of the natural mind are called memory-knowledges, but those of the rational mind are called intellectual reasons; they are also distinguished from each other by the fact that the things of the natural mind are for the most part in the light of the world, which is called the light of nature; whereas the things of the rational mind are in the light of heaven, which light is spiritual light.

5301. That shall be in the land of Egypt. That this signifies that shall be in the natural, is evident from the signification of the “land of Egypt,” as being the natural mind (see n. 5276, 5278, 5279, 5288). It is here and elsewhere said “the natural,” and thereby is meant the natural mind; for man has two minds, a rational mind and a natural mind; the rational mind is of the internal man, and the natural mind is of the external man. This mind or this man is what is meant by “the natural” simply so called. That the mind is the man himself, will be seen in what now follows.
