INTRODUCTION TO THE MASTER MINDAt 3,000,000 it sheds violet light. Above that it sheds
ultra-violet rays and other invisible radiations, some of which
can be perceived by instruments and employed by us.
Now, it has occurred to me that there must be a great
deal to be learned about the effect of those vibrations in the
great gap where the ordinary human senses are unable to
hear, see, or feel the movement. The power to send wireless
messages by ether vibrations lies in that gap, but the gap is so
great that it seems there must be much more. You must make
machines to practically supply new senses, as the wireless instru-
ments do.
Can it be said, when you think of that great gap, that there
are not many forms of vibrations that may give us results as
wonderful as, or even more wonderful than, the wireless waves?
It seems to me that in this gap lie the vibrations that we have
assumed to be given off by our brains and nerve cells when
we think. But then, again, they may be higher up, in the scale
beyond the vibrations that produce the ultraviolet rays.
[NOTE: The last sentence suggests my theory.]
Do we need a wire to carry these vibrations? Will they
not pass through the ether without a wire, just as the wireless
waves do? How will they be perceived by the recipient? Will
he hear a series of signals or will he find that another man's
thoughts have entered into his brain?
We may indulge in some speculations based on what we
know of the wireless waves, which, as I have said, are all we
can recognize of a vast series of vibrations that theoretically
must exist. If the thought waves are similar to the wireless
waves, they must pass from the brain and flow endlessly
around the world and the universe. The body and the skull
and other solid obstacles would form no obstruction to their
