As we have stated, Human Magnetism is taken up by the
organism of man, from the air he breathes; the water he drinks;
and the food he eats. It is extracted in Nature’s laboratory, and
stored up in his nervous system, in a chain of storage‑batteries,
of which the Solar Plexus is the central and chief store‑house.
From these storage‑batteries, the magnetism is drawn by the
mind and sent forth to be used for the thousands of purposes
for which it is intended. When we say, “drawn by the mind,”
we do not mean that it must be necessarily drawn by an
effort of the conscious mind, or will power,—in fact, not over
five per cent of the amount used is so drawn, the remaining
ninety‑five per cent, being drawn and used by the Instinctive
Mind, which controls the functions of the body—the workings
of the internal organs—the processes of digestion, assimilation,
and elimination—the circulation of the blood and the various
functions of the physical body, all of which are wholly, or in part,
under the control and care of the Instinctive Mind.
