I am too much an admirer of her cruelty, beloved; my entire heart is bleeding, and it cannot stop playing its tune.

This profound couplet speaks to the depth of suffering endured by true love. The poet says that he is accustomed to the cruelties of his beloved, and he is content with it. Yet, the pain is so overwhelming that his very heart and blood are ringing, as if they are playing a desperate tune. It’s a masterful depiction of a love so consuming that pain itself becomes a familiar, painful companion.
