Although many Western authorities write and speak of this method as the best known form of breathing, the Yogis know it to be but a part of a system which they have used for centuries and which they know as "The Complete Breath." It must be admitted, however, that one must be acquainted with the principles of Low Breathing before he can grasp the idea of Complete Breathing.

Let us again consider the diaphragm. What is it? We have seen that it is the great partition muscle, which separates the chest and its contents from the abdomen and its contents. When at rest it presents a concave surface to the abdomen. That is, the diaphragm as viewed from the abdomen would seem like the sky as viewed from the earth-the interior of an arched surface. Consequently the side of the diaphragm toward the chest organs is like a protruding rounded surface-like a hill. When the diaphragm is brought into use the hill formation is lowered and the diaphragm presses upon the abdominal organs and forces out the abdomen.

In Low Breathing, the lungs are given freer play than in the methods already mentioned, and consequently more air is inhaled. This fact has led the majority of Western writers to speak and write of Low Breathing (which they call Abdominal Breathing) as the highest and best method known to science. But the Oriental Yogi has long known of a better method, and some few Western writers have also recognized this fact. The trouble with all methods of breathing, other than "Yogi Complete Breathing" is that in none of these methods do the lungs become filled with air-at the best only a portion of the lung space is filled, even in Low Breathing. High Breathing fills only the upper portion of the lungs. Mid Breathing fills only the middle and a portion of the upper parts. Low Breathing fills only the lower and middle parts. It is evident that any method that fills the entire lung space must be far preferable to those filling only certain parts Any method which will fill the entire lung space must be the greatest value to Man in the way of allowing him to absorb the greatest quantity of oxygen and to store away the greatest amount of prana. The Complete Breath is known to the Yogis to be the best method of respiration known to science.

Yogi Complete Breathing includes all the good points of High Breathing, Mid Breathing and Low Breathing, with the objectionable features of each eliminated. It brings into play the entire respiratory apparatus, every part of the lungs, every air-cell, every respiratory muscle. The entire respiratory organism responds to this method of breathing, and the maximum amount of benefit is derived from the minimum expenditure of energy. The chest cavity is increased to its normal limits in all directions and every part of the machinery performs its natural work and functions.

One of the most important features of this method of breathing is the fact that the respiratory muscles are fully called into play, whereas in the other forms of breathing only a portion of these muscles are so used. In Complete Breathing, among other muscles, those controlling the ribs are actively used, which increases the space in which the lungs may expand, and also gives the proper support to the organs when needed, Nature availing herself of the perfection of the principle of leverage in this process. Certain muscles hold the lower ribs firmly in position, while other muscles bend them outward.

Then again, in this method, the diaphragm is under perfect control and is able to perform its functions properly, and in such manner as to yield the maximum degree of service.

In the rib-action, above alluded to, the lower ribs are controlled by the diaphragm which draws them slightly downward, while other muscles hold them in place and the intercostal muscles force them outward, which combined action increases the mid-chest cavity to its maximum. In addition to this muscular action, the upper ribs are also lifted and forced outward by the intercostal muscles, which increases the capacity of the upper chest to its fullest extent.

If you have studied the special features of the four given methods of breathing, you will at once see that the Complete Breath comprises all the advantageous features of the three other methods, plus the reciprocal advantages accruing from the combined action of the high-chest, mid-chest, and diaphragmatic regions, and the normal rhythm thus obtained.

In our next chapter, we will take up the Complete Breath in practice, and will give full directions for the acquirement of this superior method of breathing, with exercises, etc.

The Yogi Complete Breath is the fundamental breath of the entire Yogi Science of Breath, and the student must fully acquaint himself with it, and master it perfectly before he can hope to obtain results from the other forms of breath-mentioned and given in this book. He should not be content with half-learning it, but should go to work in earnest until it becomes his natural method of breathing. This will require work, time and patience, but without these things nothing is ever accomplished. There is no royal road to the Science of Breath, and the student must be prepared to practice and study in earnest if he expect to receive results. The results obtained by a complete mastery of the Science of Breath are great, and no one who has attained them would willingly go back to the old methods, and he will tell his friends that he considers himself amply repaid for all his work. We say these things now, that you may fully understand the necessity and importance of mastering this fundamental method of Yogi Breathing, instead of passing it by and trying some of the attractive looking variations given later on in this book. Again, we say to you: Start right, and right results will follow; but neglect your foundations and your entire building will topple over sooner or later.

Perhaps the better way to teach you how to develop the Yogi Complete Breath, would be to give you simple directions regarding the breath itself, and then follow up the same with general remarks concerning it, and then later on giving exercises for developing the chest, muscles and lungs which have been allowed to remain in an undeveloped condition by imperfect methods of breathing. Right here we wish to say that this Complete Breath is not a forced or abnormal thing, but on the contrary is a going back to first principles-a return to Nature. The healthy adult savage and the healthy infant of civilization both breathe in this manner, but civilized man has adopted unnatural methods of living, clothing, etc., and has lost his birthright. And we wish to remind the reader that the Complete Breath does not necessarily call for the complete filling of the lungs at every inhalation. One may inhale the average amount of air, using the Complete Breathing Method and distributing the air inhaled, be the quantity large or small, to all parts of the lungs. But one should inhale a series of full Complete Breaths several times a day, whenever opportunity offers, in order to keep the system in good order and condition.

The following simple exercise will give you a clear idea of what the

Complete Breath is:

(1) Stand or sit erect. Breathing through the nostrils, inhale steadily, first filling the lower part of the lungs, which is accomplished by bringing into play the diaphragm, which descending exerts a gentle pressure on the abdominal organs, pushing forward the front walls of the abdomen. Then fill the middle part of the lungs, pushing out the lower ribs, breast-bone and chest. Then fill the higher portion of the lungs, protruding the upper chest, thus lifting the chest, including the upper six or seven pairs of ribs. In the final movement, the lower part of the abdomen will be slightly drawn in, which movement gives the lungs a support and also helps to fill the highest part of the lungs.
