321. We need to realize that to all outward appearances, the spiritual world is just like the physical world. You can see lands there, mountains, hills, valleys, plains, fields, lakes, rivers, and springs like the ones in our earthly world; everything, then, that belongs to the mineral kingdom. You can see parks as well, gardens, groves, and woods, with all kinds of trees and shrubs with their fruits and seeds, smaller plants, flowers, herbs, and grasses; everything, then, that belongs to the plant kingdom. You can see all kinds of animals, birds, and fish--everything that belongs to the animal kingdom. The people there are angels and spirits.

This is prefaced to let it be known that the whole spiritual world is just like the whole physical world, the sole difference being that things there are not static and stable the way they are in a physical world because there is nothing of nature there. Everything is spiritual.
