are filled with warm mucous membrane, which coming in contact with the inhaled air Warms it so that it can do no damage to the delicate organs of the throat, or to the lungs.
No animal, excepting man, sleeps with the mouth open or breathes through the mouth, and in fact it is believed that it is only civilized man who so perverts nature's functions, as the savage and barbarian races almost invariably breathe correctly. It is probable that this unnatural habit among civilized men has been acquired through unnatural methods of living, enervating luxuries and excessive warmth.
The refining, filtering and straining apparatus of the nostrils renders the air fit to reach the delicate organs of the throat and the lungs, and the air is not fit to so reach these organs until it has passed through nature's refining process. The impurities which are stopped and retained by the sieves and mucous membrane of the nostrils, are thrown out again by the expelled breath, in exhalation, and in case they have accumulated too rapidly or have managed to escape through the sieves and have penetrated forbidden regions, nature protects us by producing a sneeze which violently ejects the intruder.
The air, when it enters the lungs is as different from the outside air, as is distilled water different from the water of the cistern. The intricate purifying organization of the nostrils, arresting and holding the impure particles in the air, is as important as is the action of the mouth in stopping cherry-stones and fish-bones and preventing them from being carried on to the stomach. Man should no more breathe through his mouth than he would attempt to take food through his nose.
Another feature of mouth-breathing is that the nasal passages, being thus comparatively unused, consequently fail to keep themselves clean and clear, and become clogged up and unclean, and are apt to contract local diseases. Like abandoned roads that soon become filled with weeds and rubbish, unused nostrils become filled with impurities and foul matter.
One who habitually breathes through the nostrils is not likely to be troubled with clogged or stuffy nostrils, but for the benefit of those who have been more or less addicted to the unnatural mouth-breathing, and who wish to acquire the natural and rational method, it may perhaps be well to add a few words regarding the way to keep their nostrils clean and free from impurities.
A favorite Oriental method is to snuff a little water up the nostrils allowing it to run down the passage into the throat, from thence it may be ejected through the mouth. Some Hindu yogis immerse the face in a bowl of water, and by a sort of suction draw in quite a quantity of water, but this latter method requires considerable practice, and the first mentioned method is equally efficacious, and much more easily performed.
Another good plan is to open the window and breathe freely, closing one nostril with the finger or thumb, sniffing up the air through the open nostril. Then repeat the process on the other nostril. Repeat several times, changing nostrils. This method will usually clear the nostrils of obstructions.
In case the trouble is caused by catarrh it is well to apply a little vaseline or camphor ice or similar preparation. Or sniff up a little witch-hazel extract once in a while, and you will notice a marked improvement. A little care and attention will result in the nostrils becoming clean and remaining so.
We have given considerable space to this subject of nostril-breathing, not only because of its great importance in its reference to health, but because nostril-breathing is a prerequisite to the practice of the breathing exercises to be given later in this book, and because nostril-breathing is one of the basic principles underlying the Yogi Science of Breath.
We urge upon the student the necessity of acquiring this method of breathing if he has it not, and caution him against dismissing this phase of the subject as unimportant.
CHAPTER VII.
FOUR METHODS OF RESPIRATION
In the consideration of the question of respiration, we must begin by considering the mechanical arrangements whereby the respiratory movements are effected. The mechanics of respiration manifest through (1) the elastic movements of the lungs, and (2) the activities of the sides and bottom of the thoracic cavity in which the lungs are contained. The thorax is that portion of the trunk between the neck and the abdomen, the cavity of which (known as the thoracic cavity) is occupied mainly by the lungs and heart. It is bounded by the spinal column, the ribs with their cartilages, the breastbone, and below by the diaphragm. It is generally spoken of as "the chest." It has been compared to a completely shut, conical box, the small end of which Is turned upward, the back of the box being formed by the spinal column, the front by the breastbone and the sides by the ribs.
The ribs are twenty-four in number, twelve on each side, and emerge from each side of the spinal column. The upper seven pair are known as "true ribs," being fastened to the breastbone direct, while the lower five pairs are called (false ribs) or "floating ribs," because they are not so fastened, the upper two of them being fastened by cartilage to the other ribs, the remainder having no cartilages, their forward ends being free.
The ribs are moved in respiration by two superficial muscular layers, known as the intercostal muscles. The diaphragm, the muscular partition before alluded to, separates the chest box from the abdominal cavity.
In the act of inhalation the muscles expand the lungs so that a vacuum is created and the air rushes in in accordance with the well known law of physics. Everything depends upon the muscles concerned in the process of respiration, which we may as, for convenience, term the "respiratory muscles." Without the aid of these muscles the lungs cannot expand, and upon the proper use and control of these muscles the Science of Breath largely depends. The proper control of these muscles will result in the ability to attain the maximum degree of lung expansion, and the greatest amount of the life giving properties of the air into the system.
The Yogis classify Respiration into four general methods, viz:
(1) High Breathing.
(2) Mid Breathing.
(3) Low Breathing.
(4) Yogi Complete Breathing.
We will give a general idea of the first three methods, and a more extended treatment of the fourth method, upon which the Yogi Science of Breath is largely based.
(1) HIGH BREATHING.
This form of breathing is known to the Western world as Clavicular Breathing, or Collarbone Breathing. One breathing in this way elevates the ribs and raises the collarbone and shoulders, at the same time drawing in the abdomen and pushing its contents up against the diaphragm, which in turn is raised.
The upper part of the chest and lungs, which is the smallest, is used, and consequently but a minimum amount of air enters the lungs. In addition to this, the diaphragm being raised, there can be no expansion in that direction. A study of the anatomy of the chest will convince any student that in this way a maximum amount of effort is used to obtain a minimum amount of benefit.
High Breathing is probably the worst form of breathing known to man and requires the greatest expenditure of energy with the smallest amount of benefit. It is an energy-wasting, poor-returns plan. It is quite common among the Western races, many women being addicted to It, and even singers, clergymen, lawyers and others, who should know better, using it ignorantly.
Many diseases of the vocal organs and organs of respiration may be directly traced to this barbarous method of breathing, and the straining of delicate organs caused by this method, often results in the harsh, disagreeable voices heard on all sides. Many persons who breathe In this way become addicted to the disgusting practice of "mouth-breathing" described in a preceding chapter.
If the student has any doubts about what has been said regarding this form of breathing, let him try the experiment of expelling all the air from his lungs, then standing erect, with hands at sides, let him raise the shoulders and collar-bone and inhale. He will find that the amount of air inhaled far below normal. Then let him inhale a full breath, after dropping the
