As there are two better methods known, we give it only passing notice, and that principally to call your attention to its short-comings.
(3) LOW BREATHING.
This form of respiration is far better than either of the two preceding forms: and of recent years many Western writers have extolled its merits, and have exploited it under the names of "Abdominal Breathing," "Deep Breathing," "Diaphragmatic Breathing," etc., etc., and much good has been accomplished by the attention of the public having been directed to the subject, and many having been Induced to substitute it for the interior and injurious methods above alluded to.

Many "systems" of breathing have been built around Low Breathing, and students have paid high prices to learn the new ( ?) systems.

But, as we have said, much good has resulted, and after all the students who paid high prices to learn revamped old systems undoubtedly got their money's worth if they were Induced to discard the old methods of High Breathing and Low Breathing.
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.
