System includes all that part of the Nervous System located principally in the thoracic, abdominal and pelvic cavities, and which is distributed to the internal organs. It has control over the involuntary processes, such as growth, nutrition, etc.
The Cerebro-Spinal System attends to all the seeing, hearing, tasting, smelling, feeling, etc. It sets things in motion; it is used by the Ego to think—to manifest consciousness. It is the instrument with which the Ego communicates with the outside world. This system may be likened to a telephone system, with the brain as the central office, and the spinal column and nerves as cable and wires respectively.
The brain is a great mass of nerve tissue, and consists of three parts, viz., the Cerebrum or brain proper, which occupies the upper, front, middle and back portion of the skull; the Cerebellum, or "little brain," which fills the lower and back portion of the skull; and the Medulla Oblongata, which Is the broadened commencement of the spinal cord, lying before and in front of the Cerebellum.
The Cerebrum is the organ of that part of the mind which manifests itself in intellectual action. The Cerebellum regulates the movements of the voluntary muscles. The Medulla Oblongata is the upper enlarged end of the spinal cord, and from it and the Cerebrum branch forth the Cranial Nerves which reach to various parts of the head, to the organs of special sense, and to some of the thoracic and abdominal organs, and to the organs of respiration.
The Spinal Cord, or spinal marrow, fills the spinal canal in the vertebral column, or "backbone." It is a long mass of nerve tissue, branching off at the several vertebrae to nerves communicating with all parts of the body. The Spinal Cord is like a large telephone cable, and the emerging nerves are like the private wires connecting therewith.
The Sympathetic Nervous System consists of a double chain of Ganglia on the side of the Spinal column, and scattered ganglia in the head, neck, chest and abdomen. (A ganglion is a mass of nervous matter including nerve cells.) These ganglia are connected with each other by filaments, and are also connected with the Cerebro-Spinal System by motor and sensory nerves. From these ganglia numerous fibers branch out to the organs of the body, blood vessels, etc. At various points, the nerves meet together and form what are known as plexuses. The Sympathetic System practically controls the involuntary processes, such as circulation, respiration and digestion.
The power or force transmitted from the brain to all parts of the body by means of the nerves, is known to Western science as "nerve force," although the Yogi knows it to be a manifestation of Prana. In character and rapidity it resembles the electric current. It will be seen that without this "nerve force" the heart cannot beat; the blood cannot circulate; the lungs cannot breathe; the various organs cannot function; in fact the machinery of the body comes to a stop without it. Nay more, even the brain cannot think without Prana be present. When these facts are considered, the importance of the absorption of Prana must be evident to all, and the Science of Breath assumes an importance even greater than that accorded it by Western science.
The Yogi teachings go further than does Western science, in one important feature of the Nervous System. We allude to what Western science terms the "Solar Plexus," and which it considers as merely one of a series of certain matted nets of sympathetic nerves with their ganglia found in various parts of the body. Yogi science teaches that this Solar Plexus is really a most important part of the Nervous System, and that it is a form of brain, playing one of the principal parts in the human economy. Western science seems to be moving gradually towards a recognition of this fact which has been known to the Yogis of the East for centuries, and some recent Western writers have termed the Solar Plexus the "Abdominal Brain." The Solar Plexus is situated in the Epigastric region, just back of the "pit of the stomach" on either side of the spinal column. It is composed of white and gray brain matter, similar to that composing the other brains of man. It has control of the main internal organs of man, and plays a much more important part than is generally recognized. We will not go into the Yogi theory regarding the Solar Plexus, further than to say that they know it as the great central store-house of Prana. Men have been known to be instantly killed by a severe blow over the Solar Plexus, and prize fighters recognize its vulnerability and frequently temporarily paralyze their opponents by a blow over this region.
The name "Solar" is well bestowed on this "brain," as it radiates strength and energy to all parts of the body, even the upper brains depending largely upon it as a storehouse of Prana. Sooner or later Western science will fully recognize the real function of the Solar Plexus, and will accord to it a far more important place then it now occupies in their text-books and teachings.
CHAPTER VI.
NOSTRIL-BREATHING VS. MOUTH-BREATHING
One of the first lessons in the Yogi Science of Breath, Is to learn how to breathe through the nostrils, and to overcome the common practice of mouth-breathing.
The breathing mechanism of Man is so constructed that he may breathe either through the mouth or nasal tubes, but it is a matter of vital importance to him which method he follows, as one brings health and strength and the other disease and weakness.
It should not be necessary to state to the student that the proper method of breathing is to take the breath through the nostrils, but alas! the ignorance among civilized people regarding this simple matter is astounding. We find people in all walks of life habitually breathing through their mouths, and allowing their children to follow their horrible and disgusting example.
Many of the diseases to which civilized man is subject are undoubtedly caused by this common habit of mouth-breathing. Children permitted to breathe in this way grow up with impaired vitality and weakened constitutions, and in manhood and womanhood break down and become chronic invalids. The mother of the savage race does better, being evidently guided by her intuition. She seems to instinctively recognize that the nostrils are the proper channels for the conveyal of air to the lungs, and she trains her infant to close its little lips and breathe through the nose. She tips its head forward when it is asleep, which attitude closes the lips and makes nostril-breathing imperative. If our civilized mothers were to adopt the same plan, it would work a great good for the race.
Many contagious diseases are contracted by the disgusting habit of mouth-breathing, and many cases of cold and catarrhal affections are also attributable to the same cause. Many persons who, for the sake of appearances, keep their mouth closed during the day, persist in mouth-breathing at night and often contract disease in this way.
Carefully conducted scientific experiments have shown that soldiers and sailors who sleep with their mouths open are much more liable to contract contagious diseases than those who breathe properly through the nostrils. An instance is related in which small-pox became epidemic on a man-of-war in foreign parts, and every death which resulted was that of some sailor or marine who was a mouth-breather, not a single nostril-breather succumbing.
The organs of respiration have their only protective apparatus, filter, or dust-catcher, in the nostrils. When the breath is taken through the mouth, there is nothing from mouth to lungs to strain the air, or to catch the dust and other foreign matter in the air. From mouth to lungs the dirt or impure substance has a clear track, and the entire respiratory system is unprotected. And, moreover, such incorrect breathing admits cold air to the organs, thereby injuring them. Inflammation of the respiratory organs often results from the inhalation of cold air through the mouth. The man who breathes through the mouth at night, always awakens with a parched feeling in the mouth and a dryness in the throat. He is violating one of nature's laws, and is sowing the seeds of disease.
Once more, remember that the mouth affords no protection to the respiratory organs, and cold air, dust and impurities and germs readily enter by that door. On the other hand, the nostrils and nasal passages show evidence of the careful design of nature in this respect. The nostrils are two narrow, tortuous channels, containing numerous bristly hairs which serve the purpose of a filter or sieve to strain the air of its impurities, etc., which are expelled when the breath is exhaled. Not only do the nostrils serve this important purpose, but they also perform an important function in warming the air inhaled. The long narrow winding nostrils
