I’ll follow thee and make a heaven of hell,
to die upon the hand I love so well.

– William Shakespeare

A Midsummer Night’s Dream, Act 2, Scene 1. Helena’s words are an expression of her passionate longing for Demetrius, as she runs after him in the forest and he continues to reject her advances. She says, with irony, that she is going to follow Demetrius and turn her hell into a heaven by getting the one she loves to kill her.
