In Vladimir Nabokov's novel "Lolita," the quote reflects a profound sentiment about mortality and the passage of time. The line suggests a poignant acceptance of life's impermanence, contrasting the vibrant experiences of life with the inevitable decay that follows. It evokes imagery of nature, where the living becomes intertwined with the remnants of the past, symbolizing both beauty and decay.

The mention of "rust and stardust" further emphasizes the transient nature of existence. It draws a connection between the earthly and the cosmic, reminding readers of their place within the universe. This duality highlights the idea that while life's experiences may fade, their essence is woven into the larger tapestry of existence, connecting personal journeys to the universal cycle of life and death.
