Hell only burns
 
Die Hölle schadt mir nichts,
     Hell                harms      me     nothing   [hell does no harm to me]
     wär ich gleich stets in ihr;
         were   I        already     always   in  it;  [even if I were already there]
Dass dich ihr Feuer brennt,
  That      you       its      fire         burns,
     das lieget nur an dir.
         that     lies         only   with you.  [that is up to you alone]
