It is therefore necessary for them first to learn what a deep breath is, and then how to take it.
Exercise I FOR THOSE WHO DO NOT KNOW WHAT A DEEP BREATH IS Before rising in the morning, remove your pillow and while flat on your back place one hand lightly on the abdomen, the other on the lower ribs.

Relax the whole body, giving up your whole weight to the bed.

Inhale through the nostrils slowly, evenly, and deeply, while mentally counting one, two, three, four, etc.

As you inhale, notice (_a_) the gradual expansion of the abdomen, (_b_) the side expansion of the lower ribs, (_c_) the rise and inflation of the chest, without raising the shoulders.

Hold the breath while mentally counting four (four seconds), then suddenly let the breath go, and notice the collapse of the abdomen and lower chest.
