"feeling pain at a distance." The name should really indicate "knowing at
a distance," in order to be properly descriptive. But as the term has
acquired a forced meaning by reason of years of usage, it will probably be
continued in popular favor. After all, names do not count, so long as the
meaning is accepted and understood.

While the term itself has been generally used in the sense of conscious
and deliberate sending and receiving of thought-waves, there is a far
wider field of phenomena really covered by it, viz., the unconscious
sending and receiving of mental and emotional vibrations. I shall take up
this phase of the subject in a moment, after I have called your attention
to the mechanism whereby the waves of thought and emotion are transmitted.

In the last chapter, you will remember that I called your attention to the
fact that there is a manifestation of energy or force (in the form of
vibrations) in every mental or emotional state. This is true not only in
the case of deep thought or vivid feeling, but also in the case of general
mental "feelings," and emotional states. During such manifestations there
is a radiation of mental or emotional vibrations from the brain or nervous
centres of the system, which flows out in all directions just as do light
and wireless electricity. The principal seats or centres of these
radiations are (1) the several brains of man, viz., the cerebrum,
cerebellum, and the medulla oblongata, respectfully; and (2) the several
great centres of nerve substance in the human system, called the plexi,
such as the solar plexus, etc.

The vibrations arising from emotional excitement are sent out principally
from the plexi, or great centres of the sympathetic nervous system. Those
arising from the more strictly mental states emanate from certain centres
and points of the brain, or brains, of the person manifesting them.
