The Canonization
By John Donne

For God's sake hold your tongue, and let me love,
Or chide my palsy, or my gout,
My five gray hairs, or ruined fortune flout,
With wealth your state, your mind with arts improve,
Take you a course, get you a place,
Observe his honor, or his grace,
Or the king's real, or his stampèd face
Contemplate; what you will, approve,
So you will let me love.
