Yes, humanity surges with uncontrolled passion, is tumultuous with
ungoverned grief, is blown about by anxiety and doubt only the wise
man, only he whose thoughts are controlled and purified, makes the
winds and the storms of the soul obey him.

Tempest-tossed souls, wherever ye may be, under whatsoever
conditions ye may live, know this in the ocean of life the isles of
Blessedness are smiling, and the sunny shore of your ideal awaits
your coming. Keep your hand firmly upon the helm of thought. In the
bark of your soul reclines the commanding Master; He does but sleep:
wake Him. Self-control is strength; Right Thought is mastery;
Calmness is power. Say unto your heart, "Peace, be still!"
