Analysis of Idea XX: An evil spirit, your beauty, haunts me still

An evil spirit, your beauty, haunts me still,
   Wherewith, alas, I have been long possess'd,
   Which ceaseth not to tempt me to each ill,
   Nor gives me once but one poor minute's rest.
   In me it speaks, whether I sleep or wake;
   And when by means to drive it out I try,
   With greater torments then it me doth take,
   And tortures me in most extremity.
   Before my face it lays down my despairs,
  And hastes me on unto a sudden death;
  Now tempting me to drown myself in tears,
  And then in sighing to give up my breath.
  Thus am I still provok'd to every evil
  By this good-wicked spirit, sweet angel-devil.
