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.
