Paul, in his writings, also mentions _the natural body_ and the _spiritual body_ while the man himself is a spirit inhabiting those vehicles. We will briefly note the constitution of the various bodies of man invisible to the physical sight but as objective to spiritual sight as the dense body to ordinary vision. _The Vital Body._ That body of ours which is composed of ether is called the “_vital body_” in Western Mystery Schools, for, as we have already seen, ether is the avenue of ingress for vital force from the sun and the field of agencies in nature which promote such vital activities as assimilation, growth and propagation. This vehicle is an exact counterpart of our visible body, molecule for molecule, and organ for organ, with one exception, which we shall note later. But it is slightly larger, extending about one and one-half inches beyond the periphery of our dense vehicle. The spleen is the entrance gate of forces which vitalize the body. In the etheric counterpart of that organ solar energy is transmuted to vital fluid of a pale rose color. From thence it spreads all over the nervous system, and after having been used in the body it radiates in streams, much as bristles protrude from a porcupine. The rays of the sun are transmitted either directly, or reflected by way of the planets and the moon. The rays directly from the sun give spiritual illumination, the rays received by way of the planets produce intelligence, morality, and soul growth, but the rays reflected by way of the moon make for physical growth, as seen in the case of plants which grow differently when planted in the light of the moon from what is the case when they are planted when the moon is dark. There is also a difference in plants sown when the moon is in barren and fruitful signs of the Zodiac. The solar ray is absorbed by the human spirit which has its seat in the center of the forehead, the stellar ray is absorbed by the brain and spinal cord, and the lunar ray enters our system through the spleen. The solar, stellar and lunar rays are three-colored, and in the lunar ray which supplies our vital force, the blue beam is the life of The Father, which causes germination, the yellow beam is the life of The Son, which is the active principle in nutrition and growth, and the red beam is the life of the Holy Spirit, which stimulates to action, dissipating the energy stored by the yellow force. This principle is particularly active in generation. The various kingdoms absorb this life-force differently, according to their constitution. Animals have only 28 pairs of spinal nerves. They are keyed to the lunar month of 28 days and therefore dependent upon a Groupspirit for an infusion of stellar rays necessary to produce consciousness. They are altogether incapable of absorbing the direct ray of the sun.
