pens, in the biological psyche, is that deeper centers of
consciousness and function come awake. Deep in the lower body the
great sympathetic center, the hypogastric plexus has been acting all
the time in a kind of dream-automatism, balanced by its corresponding
voluntary center, the sacral ganglion. At the age of twelve these two
centers begin slowly to rumble awake, with a deep reverberant force
that changes the whole constitution of the life of the individual.

And as these two centers, the sympathetic center of the deeper
abdomen, and the voluntary center of the loins, gradually sparkle into
wakeful, _conscious_ activity, their corresponding poles are roused in
the upper body. In the region of the throat and neck, the so-called
cervical plexuses and the cervical ganglia dawn into activity.

We have now another field of dawning dynamic consciousness, that will
extend far beyond the first. And now various things happen to us.
First of all actual sex establishes its strange and troublesome
presence within us. This is the massive wakening of the lower body.
And then, in the upper body, the breasts of a woman begin to develop,
her throat changes its form. And in the man, the voice breaks, the
beard begins to grow round the lips and on to the throat. There are
the obvious physiological changes resulting from the gradual bursting
into free activity of the hypogastric plexus and the sacral ganglion,
in the lower body, and of the cervical plexuses and ganglia of the
neck, in the upper body.

Why the growth of hair should start at the lower and upper sympathetic
regions we cannot say. Perhaps for protection. Perhaps to preserve
these powerful yet supersensitive nodes from the inclemency of changes
in temperature, which might cause a derangement. Perhaps for the sake
of protective warning, as hair warns when it is touched. Perhaps for a
screen against various dynamic vibrations, and as a receiver of other
suited dynamic vibrations. It may be that even the hair of the head
acts as a sensitive vibration-medium for conveying currents of
physical and vitalistic activity to and from the brain. And perhaps
from the centers of intense vital surcharge hair springs as a sort of
annunciation or declaration, like a crest of life-assertion. Perhaps
all these things, and perhaps others.

But with the bursting awake of the four new poles of dynamic
consciousness and being, change takes place in everything, the
features now begin to take
