“Life is a shrewd teacher, hardship is an unfriendly lecturer, death is a pessimistic professor, and eternity is an illuminated philosopher. Experience is an intelligent teacher, reality is an indifferent lecturer, mortality is a gloomy professor, and truth is an infallible philosopher. The past is a wise teacher, the present is an apathetic lecturer, the future is a mysterious professor, and destiny is an immutable philosopher. The mind is a clever teacher, the conscience is an annoying lecturer, the body is a sensual professor, and the soul is a mystical philosopher.”
