First of all it is necessary that you should accept and believe two
well-settled and fundamental laws.

I. _All human achievement comes about through bodily activity._

II. _All bodily activity is caused, controlled and directed by the
mind._

Give the first of these propositions but a moment's thought. You can
conceive of no form of accomplishment which is not the result of some
kind of bodily activity. One would say that the master works of poetry,
art, philosophy, religion, are products of human effort furthest
removed from the material side of life, yet even these would have
perished still-born in the minds conceiving them had they not found
transmission and expression through some form of bodily activity. You
will agree, therefore, that the first of these propositions is so
self-evident, so axiomatic, as neither to require nor to admit of formal
proof.

The second proposition is not so easily disposed of. It is in fact so
difficult of acceptance by some persons that we must make very plain its
absolute validity. Furthermore, its elucidation will bring forth many
illuminating facts that will give you an entirely new conception of the
mind and its scope and influence.

Remember, when we say "mind," we are not thinking of the brain. The
brain is but one of the organs of the body, and, by the terms of our
proposition as stated, is as much the slave of the mind as is any other
