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 anæmia. The sudden stimulating of the voluntary center may cause diarrhœa, 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 plane and the thoracic ganglion. Any excess in the sympathetic mode from the upper centers tends to burn the lungs with oxygen, weaken them with stress, and cause consumption. So it is just criminal to make a child too loving. No child should be induced to love too much. It means derangement and death at last.

But beyond the primary physiological function—and it is the business of doctors to discover the relation between the functioning of the primary organs and the dynamic psychic activity at the four primary consciousness-centers,—beyond these physical functions, there are the activities which are half-psychic, half-functional. Such as the five senses.

Of the five senses, four have their functioning in the face-region. The fifth, the sense of touch, is distributed all over the body. But all have their roots in the four great primary centers of consciousness. From the constellation of your nerve-nodes, from the great field of your poles, the nerves run out in every direction, ending on the surface of the body. Inwardly this is an inextricable ramification and communication.

And yet the body is planned out in areas, there is a definite area-control from the four centers. On the back the sense of touch is not acute. There the voluntary centers act in resistance. But in the front of the body, the breast is one great field of sympathetic touch, the belly is another. On these two fields the stimulus of touch is quite different, has a quite different psychic quality and psychic result. The breast-touch is the fine alertness of quivering curiosity, the belly-touch is a deep thrill of delight and avidity. Correspondingly, the hands and arms are instruments of superb delicate curiosity, and deliberate execution. Through the elbows and the wrists flows the dynamic psychic current, and a dislocation in the current between two individuals will cause a feeling of dislocation at the wrists and elbows. On the lower plane, the legs and feet are instruments of unfathomable gratifications and repudiations. The thighs, the knees, the feet are intensely alive with love-desire, darkly and superbly drinking in the love-contact, blindly. Or they are the great centers of resistance, kicking, repudiating. Sudden flushing of great general sympathetic desire will make a man feel weak at the knees. Hatred will harden the tension of the knees like steel, and grip the feet like talons. Thus the fields of touch are four, two sympathetic fields in front of the body from the throat to the feet, two resistant fields behind from the neck to the heels.

There are two fields of touch, however, where the distribution is not so simple: the face and the buttocks. Neither in the face nor in the buttocks is there one single mode of sense communication.

The face is of course the great window of the self, the great opening of the self upon the world, the great gateway. The lower body has its own gates of exit. But the bulk of our communication with all the outer universe goes on through the face.

And every one of the windows or gates of the face has its direct communication with each of the four great centers of the first field of consciousness. Take the mouth, with the sense of taste. The mouth is primarily the gate of the two chief sensual centers. It is the gateway to the belly and the loins. Through the mouth we eat and we drink. In the mouth we have the sense of taste. At the lips, too, we kiss. And the kiss of the mouth is the first sensual connection.

In the mouth also are the teeth. And the teeth are the instruments of our sensual will. The growth of the teeth is controlled entirely from the two great sensual centers below the diaphragm. But almost entirely from the one center, the voluntary center. The growth and the life of the teeth depend almost entirely on the lumbar ganglion. During the growth of the teeth the sympathetic mode is held in abeyance. There is a sort of arrest. There is pain, there is diarrhœa, there is misery for the baby.

And we, in our age, have no rest with our teeth. Our mouths are too small. For many ages we have been suppressing the avid, negroid, sensual will. We have been converting ourselves into ideal creatures, all spiritually conscious, and active dynamically only on one plane, the upper, spiritual plane. Our mouth has contracted, our teeth have become soft and un-quickened. Where in us are the sharp and vivid teeth of the wolf, keen to defend and devour? If we had them more, we should be happier. Where are the white negroid teeth? Where? In our little pinched mouths they have no room. We are sympathy-rotten, and spirit-rotten, and idea-rotten. We have forfeited our flashing sensual power. And we have false teeth in our mouths. In the same way the lips of our sensual desire go thinner and more meaningless, in the compression of our upper will and our idea-driven impulse. Let us break the conscious, self-conscious love-ideal, and we shall grow strong, resistant teeth once more, and the teething of our young will not be the hell it is.
