The vital force from the Sun, which surrounds us as a colorless fluid, is absorbed by the vital (etheric) body through the etheric counterpart of the spleen, wherein in undergoes a curious transformation of color.
It becomes pale rose-hued and spreads along the nerves all over the dense body. It is to the nervous system what the force of electricity is to a telegraph system. Though there be wires, instruments, and telegraph operators all in order, if the electricity is lacking, no message can be sent. The Ego, the brain, and the nervous system may be in seemingly perfect order, but if the vital force be lacking to carry the message of the Ego through the nerves to the muscles, the dense body will remain inert. This is exactly what happens when part of the dense body becomes paralyzed. The vital body has become diseased and the vital force can no longer flow. In such cases, as in most sickness, the trouble is with the finer invisible vehicles. In conscious or unconscious recognition of this fact, the most successful physicians use suggestion — which works upon the higher vehicles — as an aid to medicine. The more a physician can imbue his patient with faith and hope, the speedier disease will vanish and give place to perfect health.
During the health the vital body specializes a superabundance of vital force, which, after passing through a dense body, radiates in straight lines in every direction from the periphery thereof, as the radii of a circle do from the center; but during ill-health, when the vital body becomes attenuated, it is not able to draw to itself the same amount of force and in addition the dense body is feeding upon it. Then the lines of the vital fluid which pass out from the body are crumpled and bent, showing the lack of force behind them. In health the great force of these radiations carries with it germs and microbes which are inimical to the health of the dense body, but in sickness, when the vital force is weak, these emanations do not so readily eliminate disease germs. Therefore the danger of contracting disease is much greater when the vital forces are low than when one is in robust health.
In cases where parts of the dense body are amputated, only the planetary ether accompanies the separated part. The separate vital body and the dense body disintegrate synchronously after death. So with the etheric counterpart of the amputated limb. It will gradually disintegrate as the dense member decays, but in the meantime the fact that the man still possesses the etheric limb accounts for his assertion that he can feel his fingers or suffers pain in them. There is also a connection with a buried member, irrespective of distance. A case is on record where a man felt severe pain, as if a nail had been driven into the flesh of an amputated limb, and he persisted until the limb was exhumed, when it was found that a nail had been driven into it at the time it was boxed for burial. The nail was removed and the pain instantly stopped. It is also in accordance with these facts that people complain of pain in a limb for perhaps two or three years after the amputation. The pain will then cease. This is because the disease remains in the still undetached etheric limb, but as the amputated part disintegrates, the etheric limb follows suit and thus the pain ceases.
