e. Yield yourself to the
slightest pressure of his hands or arms and you will soon come to the
object of which he has been thinking. If he is unfamiliar with the
impelling energy of thought, he will charge the result to mind-reading.

[Sidenote: Illustrative Experiments]

The same law is illustrated by a familiar catch. Ask a friend to define
the word "spiral." He will find it difficult to express the meaning in
words. And nine persons out of ten while groping for appropriate words
will unconsciously describe a spiral in the air with the forefinger.

Swing a locket in front of you, holding the end of the chain with both
hands. You will soon see that it will swing in harmony with your
thoughts. If you think of a circle, it will swing around in a circle. If
you think of the movement of a pendulum, the locket will swing back and
forth.

These experiments not only illustrate the impelling energy of thought
and its power to induce bodily action, but they indicate also that the
bodily effects of mental action are not limited to bodily movements that
are conscious and voluntary.

[Sidenote: Scope of Mind Power]

_The fact is, every mental state whether you consider it as involving an
act of the will or not, is followed some kind of bodily effect, and
every bodily action is preceded by some distinct kind of mental
activity. From the practical science point of view every thought causes
its particular bodily effects._

This is true of simple sensations. It is true of impulses, ideas and
emotions. It is true of pleasures and pains. It is true of conscious
mental activity. It is true of unconscious mental activity. It is true
of the whole range of mental life.

Since the mental conditions that produce bodily effects are not limited
to those mental conditions in which there is a conscious exercise of the
will, it follows that _the bodily effects produced by mental action are
not limited to movements of what are known as the voluntary muscles._

On the contrary, they include changes and movements in all of the
so-called involuntary muscles, and in every kind of bodily structure.
They include changes and movements in every part of the physical
organism, from changes in the action of heart, lungs, stomach, liver
and other viscera, to changes in the secretions of glands and in the
caliber of the tiniest blood-vessels. A few instances such as are
familiar to the introspective experience of everyone will illustrate the
scope of
