The solar plexus and the lumbar ganglion, great nerve-centers below the diaphragm, act as the dynamic origin of all consciousness in man, and are immediately polarized by the other two nerve-centers, the cardiac plexus and the thoracic ganglion above the diaphragm.

At these four poles the whole flow, both within the individual and from without him, of dynamic consciousness and dynamic creative relationship is centered.

These four first poles constitute the first field of dynamic consciousness for the first twelve or fourteen years of the life of every child.
And then a change takes place.

It takes place slowly, gradually and inevitably, utterly beyond our provision or control.

The living soul is unfolding itself in another great metamorphosis.
What happens, in the biological psyche, is that deeper centers of consciousness and function come awake.
