In Victor Hugo's "Les Miserables," the protagonist faces numerous trials and tribulations yet finds solace in an inner strength that empowers him to endure hardships. This strength, rooted in the soul, highlights the capacity of the human spirit to rise above physical constraints and challenges. It signifies a profound connection between emotional resilience and the ability to withstand life's adversities.

The quote suggests that the soul has the power to uplift the body, providing support during difficult times. It metaphorically portrays the soul as a bird, symbolizing freedom and endurance. Even when confined, like a bird in a cage, the soul can elevate one's spirit and foster hope. Through this perspective, Hugo emphasizes the importance of inner strength in overcoming life's obstacles.
