Goe, and catche a falling starre,
Get with child a mandrake roote,
Tell me, where all past yeares are,
Or who cleft the Divels foot,
Teach me to heare Mermaides singing,
Or to keep off envies stinging,
And finde
What winde
Serves to advance an honest minde.
If thou beest borne to strange sights,
Things invisible to see,
Ride ten thousand daies and nights,
In his litany of impossible feats, Donne pointedly includes that of making people more honest. 
 The pattern of short and long line-lengths gives the stanza a varying pace, reflecting perhaps the speaker’s impatience or annoyance. 
 The two short lines build tension, slowing the pace and creating suspense before the message of the stanza is revealed.
