“Correct breathing also performs a constant massage of the internal organs by raising them up and down, thus curing constipation when it is caused by faulty insufficient breathing (as is often the case) which holds the muscles of the abdomen in a static position. Therefore the first thing to do is to make sure that you know how to breathe from the physical standpoint, and how to control the muscle of the diaphragm. This muscle forms the dividing line between the chest and the stomach just below the ribs. Place the fingers upon the diaphragm muscle just below the ribs and under the centre breast bone. In this arched hollow lies the muscle upon which correct breathing depends. Take a slow breath, drawing the muscle upwards and inwards, following its movement with the fingers, fill the lungs with air right up to the collarbones. Then breathe out slowly whilst tucking the diaphragm still further inwards and upwards!”

“Matt Morgan: [To Russell] How have you developed pectoral muscles when you barely do anything for yourself?”

“And what is the relationship of muscle to bone? Through its ability to contract or shorten itself, the muscle brings two bones into a new angular relationship.... The position of two bones toward each other must change if the muscle so decides.
Bones give support to the total organism; also when in motion.
Muscles have a higher function because they act beside each other.
One bends, the other stretches.
One bone alone achieves nothing.”

“That’s what violence was: emotion leaking out from consciousness into the physical world, linking up with the muscles of the arms and shoulders and diaphragm and, inevitably, the face. Stifle emotion during an act of violence and the face becomes a blank, unreadable mask.”

“Oprah: Is there a muscle you use for performing?
Billy: Yes — my brain.”

“In this way, we influence the muscles of physiognomy [facial expression] and it is possible for us to arouse any passion or sentiment whatsoever; the contraction of the interconnected muscles, constituting “the anatomy of expression”, evokes in the brain of the hypnotised person certain impressions just as these, in the waking state, determine the whole facial expression. It is thus merely a reversal of the usual order [of causation] between the emotions and their physical expressions.”

“The human brain performs the function of thinking as involuntarily as the chest the function of breathing. However, we can, by our will, stop breathing for a while, and accelerate or retard the breathing movements. In the same way, the will can control the thoughts. We may choose any object as the subject matter of our thought, and yet we may quickly convince ourselves that the power of our will and the freedom of the mind are not any greater than the freedom of the chest in breathing.”

“It is not by muscle, speed, or physical dexterity that great things are achieved, but by reflection, force of character, and judgment.”

“Poetry is the most bodliy of arts, the medium of poetry is the column of breath rising from the diaphragm in the individual's chest to be shaped into meaning sounds inside the mouth of whoever undertakes to say the poem.”

“How art thou out of breath when thou hast breath
To say to me that thou art out of breath?”
