In Victor Hugo's "Les Miserables," the author reflects on the transformative power of light. The quote emphasizes that light, specifically with its waves, is crucial for the passage of larvae, symbolizing hope and enlightenment. It suggests that just as light affects the larvae, it can also illuminate and uplift those in society who are struggling or marginalized.

This passage underscores a broader theme in the novel: the importance of guidance and awakening in the face of darkness. By shedding light on the scenarios that plague humanity, Hugo encourages readers to strive for understanding, compassion, and the betterment of society by illuminating the lives of the downtrodden.
