but here it applies to the material, not to the vital relation. It is
from the lumbar ganglion that the dynamic vibrations are emitted which
thrill from the stomach and bowels, and promote the excremental
function of digestion. It is the solar plexus which controls the
assimilatory function in digestion.

So, in the first division of the egg-cell is set up the first plane of
psychic and physical life, remaining radically the same throughout the
whole existence of the individual. The two original nuclei of the
egg-cell remain the same two original nuclei within the corpus of the
adult individual. Their psychic and their physical dynamic is the same
in the solar plexus and lumbar ganglion as in the two nuclei of the
egg-cell. The first great division in the egg remains always the same,
the unchanging great division in the psychic and the physical
structure; the unchanging great division in knowledge and function. It
is a division into polarized duality, psychical and physical, of the
human being. It is the great vertical division of the egg-cell, and of
the nature of man.

Then, this division having taken place, there is a new thrill of
conjunction or collision between the divided nuclei, and at once the
second birth takes place. The two nuclei now split horizontally. There
is a horizontal division across the whole egg-cell, and the nuclei are
now four, two above, and two below. But those below retain their
original nature, those above are new in nature. And those above
correspond again to those below.

In the developed child, the great horizontal division of the egg-cell,
resulting in four nuclei, this remains the same. The horizontal
division-wall is the diaphragm. The two upper nuclei are the two
great nerve-centers, the cardiac plexus and the thoracic ganglion. We
have again a sympathetic center primal in activity and knowledge, and
a corresponding voluntary center. In the center of the breast, the
cardiac plexus acts as the great sympathetic mode of new dynamic
activity, new dynamic consciousness. And near the spine, by the wall
of the shoulders, the thoracic ganglion acts as the powerful voluntary
center of separateness and power, in the same vertical line as the
lumbar ganglion, but horizontally so different.

Now we must change our whole feeling. We must put off the deep way of
understanding which belongs to the lower body of our nature, and
transfer ourselves into the upper plane, where being and functioning
