en bloc_. So I grind away
uphill, and sweat my guts out, as they say.

Well, well--my body is my bicycle: the whole middle of me is the
saddle where sits the rider of my soul. And my front wheel is the
cardiac plane, and my back wheel is the solar plexus. And the brakes
are the voluntary ganglia. And the steering gear is my head. And the
right and left pedals are the right and left dynamics of the body, in
some way corresponding to the sympathetic and voluntary division.

So that now I know more or less how my rider rides me, and from what
centers controls me. That is, I know the points of vital contact
between my rider and my machine: between my invisible and my visible
self. I don't attempt to say what is my rider. A bicycle might as well
try to define its young Miss by wriggling its handle-bars and ringing
its bell.

However, having more or less determined the four primary motions, we
can see the further unfolding. In a child, the solar plexus and the
cardiac plexus, with corresponding voluntary ganglia, are awake and
active. From these centers develop the great functions of the body.

As we have seen, it is the solar plexus, with the lumbar ganglion,
which controls the great dynamic system, the functioning of the liver
and the kidneys. Any excess in the sympathetic dynamism tends to
accelerate the action of the liver, to cause fever and constipation.
Any collapse of the sympathetic dynamism causes anaemia. The sudden
stimulating of the voluntary center may cause diarrhoea, and so on.
But all this depends so completely on the polarized flow between the
individual and the correspondent, between the child and mother, child
and father, child and sisters or brothers or teacher, or
circumambient universe, that it is impossible to lay down laws,
unless we state particulars. Nevertheless, the whole of the great
organs of the lower body are controlled from the two lower centers,
and these organs work well or ill according as there is a true dynamic
_psychic_ activity at the two primary centers of consciousness. By a
_true_ dynamic psychic activity we mean an activity which is true to
the individual himself, to his own peculiar soul-nature. And a dynamic
psychic activity means a dynamic polarity between the individual
himself and other individuals concerned in his living; or between him
and his immediate surroundings, human, physical, geographical.

On the upper plane, the lungs and heart are controlled from the
cardiac
