To them that ask: Where hast thou seen the Gods, or how knowest thou certainly that there be Gods, that thou art so devout in their worship? I answer: Neither have I seen my own soul, and yet I respect and honor it.
Marcus AureliusOur life is what our thoughts make it. Do every act of your life as if it were your last. In a word, your life is short. You must make the most of the present with the aid of reason and justice. Since it is possible that you may be quitting life this very moment, govern every act and thought accordingly.
Marcus Aurelius
