CONCENTRATION 783more than ten thousand years the battle has raged between ignorance,
superstition, and fear on the one side, and intelligence on the other,
we have picked up some useful knowledge.
Among the fragments of useful knowledge gathered, we have
discovered and classified the elements of which all physical matter
consists. By study and analysis and comparison, we have discovered
the "bigness" of the material things in the universe as they are rep-
resented by the suns and stars, some of them over ten million times
as large as the earth.
We have also discovered the "littleness" of things by reducing
matter to molecules, then to atoms, which are in turn made up of
electrons that are themselves comprised of even smaller units, all
constantly in rapid motion. And thus it is said that in every drop of
water and every grain of sand the entire principle upon which the
whole universe operates is duplicated.
How do we know these things to be true? Through the aid of
the mind.
In the physical or material world, whether one is looking at the
largest star that floats through the heavens or the smallest grain of
sand to be found on earth, the object under observation is but an
organized collection of molecules, atoms, and electrons.
Man knows much about the physical facts of the universe. The
next great scientific discovery may well be proof of my belief that
in some way every human brain may be both a broadcasting and a
receiving station; that every thought vibration released by the brain
may be picked up and interpreted by all other brains that are in
harmony with the rate of vibration of the broadcasting brain.
I am of the opinion, and not without substantial evidence to
support me, that it is possible for one to develop the ability of
fixing their attention so highly that they may "tune in" and under-
stand what is in the mind of any person. But this is not all, nor is
it the most important part of a hypothesis at which I have arrived
