Explaining the type of design that was built into the universe at creation would take many volumes. (A little sketch of it will appear under the next subheading, on creation (Sections 75–80)).
One point that needs to be understood is this: Each and every thing in the universe was created with its own design so that it would continue to exist on its own. This happened from the very beginning so that each thing could become part of the overall design of the universe. The purpose is that the individual designs shall continue to exist within the universal design so that all are one.
Now for some examples. The human being was created with a design of its own, and also each individual part of a human being was created with a design of its own. The head has its own design, the body has its. The heart, the lungs, the liver, the pancreas, and the stomach have their own designs. Every organ of motion called a muscle has its own design. Every organ of sensation, such as the eye, the ear, and the tongue, has its own design. In fact, there is not a capillary or a fibril in the human body that lacks its own design. Yet all these countless parts connect with the overall design and join up with it in such a way that together they form one overall design.
The same applies to all other things. A mere list of them is enough for illustration. Every animal on land, every bird in the sky, every fish in the sea, every reptile, in fact, every insect even down to a grub has its own design built in from creation. Likewise every tree, shrub, bush, and vegetable has its own design. Furthermore, every stone and every mineral, even down to every type of dust on the earth has its own design.
