Every mental state will express its nature
in body, mind and character.
Every mental state
produces a certain chemical effect upon the body.
Mental states have a tendency
to work themselves out into physical conditions.
Think constantly on the fact
that the states of mind are the causes,
and the conditions of the body the effects,
and that you can change the effects by changing the causes.
One must become master
over his thoughts and feelings
and learn to create only those mental states
that have a harmonious and wholesome effect on the body.
