Absolute relaxation, therefore can only
exist during those few seconds of respite which we allow when we hold
our breath with the lungs empty. Having completely emptied the lungs
and held the breath for a few seconds, you will soon realize that your
breathing is attempting to start up on its own - therefore relax your
stomach and allow the breath to flow. As air enters the lungs, the
stomach expands and rises, because the dome of the diaphragm has
flattened, and not because the muscles in the abdominal region have
contracted. People believe, often in all good faith, that they are
"breathing from the stomach", because they are flexing their abdominal
muscles. In fact, the latter should be relaxed, and must remain so
throughout the inhalation. The lungs gradually fill with air from
beneath. the inhalation will be slow, easy and unquestionably silent.
If you do not hear yourself breathing it means that your respiration
has acquired the correct slowness. If audible it means you have inhaled
with much too haste.
