320. [312] There are three natural atmospheres arising from the sun of the world, and there are three spiritual atmospheres arising from the sun of heaven, which is the Lord. The three natural atmospheres arising from the sun of the world are the purer ether, which is universal, from which is all gravitation; the middle ether, which forms the vortex around the planets, in which are the moons and the satellites, from which is magnetism; and the ultimate ether which is the air. By these three atmospheres all the corporeal and material things of the earth are held together, which are so composed as to be applicable to those three degrees. The three spiritual atmospheres arising from the sun of heaven, are those in which are the angels of the three heavens. In the two higher atmospheres are the angels of the Lord's celestial kingdom; in the third and the first natural, which is pure ether, are the angels of the Lord's spiritual kingdom, and in the atmospheres following those two which are the middle and the ultimate ether, which is the air, are men while they are in the natural world.
