321. It should be known that in outward appearance the spiritual world is just like the natural world. One sees there lands, mountains, hills, valleys, plains, fields, lakes, rivers, and springs, just as in the natural world, thus all the phenomena belonging to the mineral kingdom. One sees also parks, gardens, groves, and forests, in which are found trees and bushes of every kind, with fruits and seeds, and plants, flowers, herbs, and grasses, thus all the phenomena belonging to the plant kingdom. One sees animals, birds, and fish of every kind, thus all the phenomena belonging to the animal kingdom. A person there is an angel or spirit. This much is premised in order to make it known that the universe of the spiritual world is just like the universe of the natural world, the only difference being that the phenomena which exist there are not fixed and set like phenomena in the natural world, because nothing there is natural, but everything spiritual.
