Sustaining laughter and extension, sympathetically and joyously
elevate and expand the chest as far as possible.
Feel the breast bone separate farther from the spine, easily and
naturally as in the expression of joyous courage.
Expand slowly, sustain the expansion, gradually release, then rest, that
is to say, perform the exercise in the same quadruple rhythm of the
harmonic extension.
In this exercise you should feel a deepening of the chest chamber.
It is well at first, until you get the exercises correctly, to place one
hand at the back, the other on the chest, and in expanding to feel the
two hands separate.
This expansion should be sustained for several seconds. The release
should follow gradually. There should be a repetition of the expansion;
you should feel a sympathetic activity all through the chest and torso.
Sudden collapses should at all times be avoided, and they should
especially be avoided in exercises of the chest and of the central
organs.
The free, expansive facility of the whole chest is the measure of the
health, strength, grace and normal actions of a human being. It is of
primary importance.
