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 diarrhoea, there is misery for the baby.
