As the sun of the natural world is pure fire, and therefore dead, the heat proceeding from it is also dead, likewise the light proceeding from it is dead; so also are the atmospheres, which are called ether and air, and which receive in their bosom and carry down the heat and light of that sun; and as these are dead so are each and all things of the earth which are beneath the atmospheres, and are called soils, yet these, one and all, are encompassed by what is spiritual, proceeding and flowing forth from the sun of the spiritual world. Unless they had been so encompassed, the soils could not have been stirred into activity, and have produced forms of uses, which are plants, nor forms of life, which are animals; nor could have supplied the materials by which man begins and continues to exist.
