In all his trials he felt encouraged and sometimes even upbourne by a secret force within. The soul helps the body, and at certain moments uplifts it. It is the only bird which sustains its cage.
In Victor Hugo's "Les Miserables," the protagonist endures numerous hardships, yet he finds a hidden strength that propels him forward. This inner force acts as a source of encouragement, allowing him to rise above his challenges. The notion suggests that the soul possesses a unique ability to invigorate and uplift the physical self, especially during times of struggle.
Hugo metaphorically describes the soul as a bird, symbolizing freedom and resilience. Despite being confined by life's difficulties, the soul enables the individual to endure and thrive, illustrating the profound connection between spiritual and physical well-being. This perspective emphasizes the importance of inner strength in overcoming adversity.
