away again from the earth, the two upper centers meanwhile corresponding implicitly in the balance of the upper body. It is a chain of spontaneous activity in the four primary centers, establishing a circuit through the whole body. But the positive poles are the lower centers. And the brain has probably nothing at all to do with it. Even the desire to walk is not born in the brain, but in the primary nuclei.

The same with the use of the hands and arms. It means the establishment of a pure circuit between the four centers, the two upper poles now being the positive, the lower the negative poles, and the hands the live end of the wire. Again the brain is not concerned. Probably, even in the first deliberate grasping of an object, the brain is not concerned. Not until there is an element of recognition and sensation-memory.
