There are three motives for which we live; we live for the body, we live for the mind, we live for the soul. No one of these is better or holier than the other; all are alike desirable, and no one of the three—body, mind, or soul—can live fully if either of the others is cut short of full life and expression.
You must lay aside your greed; have no unworthy motive in your desire to become rich and powerful. It is legitimate and right to desire riches, if you want them for the sake of your soul, but not if you desire them for the lists of the flesh.
