Just as in the case of the manifestation of
electricity in which certain chemical elements are consumed, or
transformed, so in the case of mental or emotional activity there is a
consuming or transformation of the substance of which the nervous system
is composed. When I say "nervous system" in this connection, I include the
brain, or brains of man--for these are but a part of his great nervous
system in which all emotional or mental activity is manifested.
Moreover, just as there is no real destruction of matter in any of
Nature's processes--all seeming destruction being but a transformation--so
in the case before us there is a transformation of the energy released in
the thought or emotional process. We may grasp this idea more clearly if
we consider what takes place into transformation of electrical energy. For
instance, transmit a strong current of electricity over a fine wire, or
filament of carbon, and lo! the current is transformed into light. Use
another kind of channel of transmission, and the current is transformed
into heat. Every electric light, or electric heating apparatus is proof
of this. In the same way, the electric current is sent into space in the
form of wireless waves. These waves coming in contact with certain forms
of apparatus are transformed into forms of force which are registered and
interpreted by the wireless operator.
