Our two souls therefore, which are one,
Though [you] must go, endure not yet
A breach, but an expansion,
Like gold to airy thinness beat….
 
If they be two, they are two so
As stiff twin compasses are two …
Thy firmness makes my circle just,
And makes me end where I begun.
 
“A Valediction: Forbidding Mourning”
John Donne
