organ of the body. To say that the mind controls the body presupposes
that mind and body are distinct entities, the one belonging to a
spiritual world, the other to a world of matter.

That the mind is master of the body is a settled principle of science.
But we realize that its acceptance may require you to lay aside some
preconceived prejudices. You may be one of those who believe that the
mind is nothing more nor less than brain activity. You may believe that
the body is all there is to man and that mind-action is merely one of
its functions.

[Sidenote: First Step Toward Self-Realization]

If so, we want you nevertheless to realize that, while as a matter of
philosophic speculation you retain these opinions, you may at the same
time for practical purposes regard the mind as an independent causal
agency and believe that it can and does control and determine and
_cause_ any and every kind of bodily activity. We want you to do this
because this conclusion is at the basis of a practical system of mental
efficiency and because, as we shall at once show you, it is capable of
proof by the established methods of physical science.
