The most prominent of the sensory nerves are those of the olfactory, optic, auditory, gustatory, tactile and thermal. To these should be added that of cenesthesia, conscious existence, painful or pleasurable, depression or exaltation, the general sense of bodily, or self-existence, the subconscious sensation by the functioning of the internal organs. Sensory impressions are the effects of external agents or bodies upon the organs of sense. These external agents or bodies are always the same, impulses as originated are always perfect, if the nervous system is in a normal condition, the impressions, afferent impulses, can not be otherwise than normal. We have the spiritual and physical impulses, those from the creator and the mind.
All efferent impulses are motor.
All motor impulses, whether of the spirit or the mind, are normal, providing the nerves of transmission are of normal tension. All thoughts, orders, commands, directions of the mind, known as impulses, are normal if voluntary, the lines of communication are normal. All thoughts, orders, commands, directions of the spirit, a segment of the Universal Intelligence, contains in miniature all intelligence and qualities of the All-Wise Spirit, just as one drop of the ocean contains all the qualities of the briny deep. The body when diseased manifests no new functions, develops no new forms of energy, adds no new space or accommodation. While the larger share of diseases, abnormal functionating, are because of trauma, toxine and autosuggestion, there are minor causes such as inhalation of gas, smoke or flame, lack of food, water, or air, decompression of the atmosphere in tunnels and caisons, an excess or a deficiency of heat, local exposure to the extremes of heat or cold which induces necroses, and exposure to X-rays may lead to caries.
