There is evidence for this in every detail of the animal kingdom, in every detail of the plant kingdom, and in every detail of the mineral kingdom.
We can see ourselves reflected in every detail of the animal kingdom from the fact that all kinds of animal have in common with us members for locomotion, sensory organs, and the inner organs that support these activities. They also have their impulses and desires like our own physical ones. They have the innate knowledge proper to their desires, with an apparently spiritual element visible in some of them, more or less obvious to the eye in the beasts of the earth, the fowl of the heavens, bees, silkworms, ants, and the like. This is why merely earthly-minded people regard the living creatures of this kingdom as much like themselves, lacking only speech.
We can see ourselves reflected in every detail of the plant kingdom in the way plants grow from seeds and go through their successive stages of life. They have something like marriages with births that follow. Their vegetative “soul” is the function to which they give form. There are many other ways in which they reflect us, which some writers have described.
We can see ourselves reflected in every detail of the mineral kingdom simply in its effort to produce the forms that reflect us—all the details of the plant kingdom, as I have just noted—and to perform its proper functions in this way. The moment a seed falls into earth’s lap, she nurtures it and from all around offers it resources from herself for its sprouting and emerging in a form representative of humanity. We can see this effort in solid mineral materials if we look at deep-sea corals or at flowers in mines, where they spring from minerals and metals. This effort toward becoming plant life and thereby performing a useful function is the outermost element of Divinity in created things.
Just as there is an energy in earth’s minerals toward plant growth, there is an energy in plants toward movement. This is why there are various kinds of insect that are responsive to the fragrances they give off. We will see later [Sections 157–158] that this is not caused by the warmth of our world’s sun but comes through it, from life, according to the recipient vessels.
What has been cited thus far tells us that there is some reference to the human form in everything in the created universe, but it enables us to see this fact only obscurely. In the spiritual world, though, people see this clearly. Everything in the three kingdoms exists there as well, surrounding each angel. Angels see these things around themselves and also are aware that they are pictures of their own selves. In fact, when the very heart of their understanding is opened, they recognize themselves and see their own image in their surroundings, almost like a reflection in a mirror.
We can be quite certain, on the basis of all this and of many other things consistent with it (which it would take too long to include) that God is a person and that the created universe is an image of him. The overall totality offers a reflection of him, just as specific aspects offer reflections of us.
