The Hindu-Yogi Science of Breath1700
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 diaphragmic 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.
