Here you will find the Poem Mutation of poet William Cullen Bryant
They talk of short-lived pleasure--be it so-- Pain dies as quickly; stern, hard-featured pain Expires, and lets her weary prisoner go. The fiercest agonies have shortest reign; And after dreams of horror, comes again The welcome morning with its rays of peace. Oblivion, softly wiping out the stain, Makes the strong secret pangs of pain to cease: Remorse is virtue's root; its fair increase Are fruits of innocence and blessedness; Thus joy, o'erborne and bound, doth still release His young limbs from the chains that round him press. Weep not that the world changes--did it keep A stable, changeless state, 'twere cause indeed to weep.
