I see that any materialism in life coarsens the soul, and that the hunger of the body and the appetites of the flesh desecrate always, and often destroy.
I have said that the soul is not more than the body, And I have said that the body is not more than the soul, And nothing, not God, is greater to one than one's-self is.
There is nothing more harmful to you than improving only your material, animal side of life. There is nothing more beneficial, both for you and for others, than activity directed to the improvement of your soul.
