SYMBOLS and ILLUSTRATIONS

These three pages provide the graphics referenced in the second paragraph of page xx. They are from the Symbols, Illustrations and Charts section of Thinking and Destiny.

	THE PHYSICAL PLANE OF THE HUMAN PHYSICAL WORLD and its FOUR STATES OF MATTER

Fig. I-D

In the four substates of the solid state are the stars, sun, moon, and the earth, (Fig. I-E).

* * *

All these states are invisible to the human eye, but some of the objects in the four substates of the solid state can be perceived by the human.

	THE SOLID STATE OF MATTER and its FOUR SUBSTATES

Fig. I-E

The visible physical universe is of and in the four substances of the solid state of the physical plane of the temporal human physical world, namely: the stars in the radiant-solid, the solar universe in the airy-solid, the moon in the fluid-solid, and the earth in the solid-solid substate of the solid state of matter.

* * *

In the four substates of the solid state is also the fourfold physical human body, (Fig. III), the visible solid-solid body corresponding to the earth.

THE SPINAL CORD and its Relation to the Spinal Column

The spinal cord proper reaches from the base of the brain to about the junction of the 12th dorsal and the 1st lumbar vertebrae; its prolongation downward is called the terminal filament, which is anchored below to the coccyx. The spinal cord has a central canal, the prolongation downward of the ventricles of the brain; below, in the embryo, this canal reaches to the end of the terminal filament, but in the adult it usually becomes clogged up within the filament and disappears more or less, in the run of human beings.

The spinal column is divided into five sections: the cervical, dorsal, and lumbar vertebrae, and the sacrum and coccyx. Bony processes and the shape of the vertebrae create openings on both sides through which pass spinal nerves to the neck, trunk, and upper and lower extremities, (Fig. VI-A, b).

	THE SYMPATHETIC OR INVOLUNTARY NERVOUS SYSTEM

This system consists of two main trunks or cords of ganglia (nerve centers), extending from the base of the brain to the coccyx, and situated partly on the right and left sides and partly in front of the spinal column; and, further, of three great nerve plexuses and many smaller ganglia in the body cavities; and of numerous nerve fibers extending from these structures. The two cords converge above in a small ganglion in the brain, and below in the coccygeal ganglion in front of the coccyx.

Fig. VI-C

In Fig. VI-B, to the left of the spinal column, is indicated one of the two cords of the involuntary nervous system. From it are seen to extend widespread ramifications of nerve fibers, which form the plexuses that are spread like spider webs over the digestive and the other organs in the body cavities; in the solar plexus they are joined by the vagus nerve of the voluntary system.

Fig. VI-C is a sketch indicating the two ganglionic cords of the involuntary system, converging below; running down between them is the spinal cord, terminating near the coccyx. On the sides are indicated the kidneys, topped by the adrenals.
