There are three lessons I would write-
Three words, as with a burning pen,
In tracings of eternal light,
Upon the heart of men.

Have hope! though clouds environ round,
And gladness hides her face in scorn,
Put thou the shadow from thy brow,
No night but hath its morn.

Have love! not love alone for one,
But man as man thy brother call,
And scatter like the circling sun,
Thy charities on all.

Friedrich Schiller
