just as soon as the food is _tasted_ in the mouth, a purely mental
process, the stomach begins to well forth those fluids that are suitable

The press recently contained an account of a motorcycle race in Newark,
New Jersey. The scene was a great bowl-shaped motor-drome. In the midst
of cheering thousands, when riding at the blinding speed of ninety-two
miles an hour, the motorcycle of one of the contestants went wrong. It
climbed the twenty-eight-foot incline, hurled its rider to instant death
and crashed into the packed grandstand. Before the whirling mass of
steel was halted by a deep-set iron pillar four men lay dead and
twenty-two others unconscious and severely injured. Then the twisted
engine of death rebounded from the post and rolled down the saucer-rim
of the track.

Around the circular path, his speed scarcely less than that of his
ill-fated rival, knowing nothing of the tragedy, hearing nothing of the
screams of warning from the crowd, came another racer. The frightened
throng saw the coming of a second tragedy. The sound that came from the
crowd was a low moaning, a sighing, impotent, unconscious prayer of the
thousands for the mercy that could not come. The second motorcycle
struck the wreck, leaped into the air, and the body of its rider shot
fifty feet over the handlebars and fell at the bottom of the track
unconscious. Two hours later he was dead.

What was the effect of this dreadful spectacle upon the onlookers?
Confusion, cries of fright and panic, while throughout the grandstand
women fainted and lay here and there unconscious. Many were afflicted
with nausea. With others the muscles of speech contracted convulsively,
knees gave way, hearts "stopped beating." Observe that these were wholly
the effects of _mental_ action, effects of _sight_ and _sound
sensations_.

Why multiply instances? All that you need to do to be satisfied that the
mind is directly responsible for any and every kind of bodily activity
is to examine your own experiences and those of your friends. They will
afford you innumerable illustrations.

You will find that not only is your body constantly doing things because
your mind wills that it should do them, but that your body is
incessantly doing things simply because they are the expression of a
passing thought.

The law that _E
