Here you will find the Poem Opposition of poet Sidney Lanier
Of fret, of dark, of thorn, of chill, Complain no more; for these, O heart, Direct the random of the will As rhymes direct the rage of art. The lute's fixt fret, that runs athwart The strain and purpose of the string, For governance and nice consort Doth bar his wilful wavering. The dark hath many dear avails; The dark distils divinest dews; The dark is rich with nightingales, With dreams, and with the heavenly Muse. Bleeding with thorns of petty strife, I'll ease (as lovers do) my smart With sonnets to my lady Life Writ red in issues from the heart. What grace may lie within the chill Of favor frozen fast in scorn! When Good's a-freeze, we call it Ill! This rosy Time is glacier-born. Of fret, of dark, of thorn, of chill, Complain thou not, O heart; for these Bank-in the current of the will To uses, arts, and charities.
