In Vladimir Nabokov's novel "Lolita," the opening line captures the intense fixation and conflicting emotions of the protagonist. The phrase "Light of my life, fire of my loins" conveys both passionate desire and deep obsession, highlighting the complexity of love intertwined with guilt and longing. This striking juxtaposition sets the tone for the tumultuous relationship that unfolds throughout the story.

The quote reflects the destructive nature of the narrator's obsession, painting his feelings as both illuminating and consuming. By referring to his obsession as "my sin, my soul," Nabokov emphasizes the moral ambiguity and emotional turmoil that defines the character's existence. This encapsulation of desire serves as a powerful entrance into the dark themes explored in "Lolita."
