The mind is an extraordinary entity that often endures suffering that isn't visible on the surface. People may appear fine outwardly, but internal wounds can cause significant pain. This quote illustrates that emotional and psychological scars exist, even when they aren't apparent to others.

Jodi Picoult emphasizes resilience, reminding us that healing is always possible, even when the pain is not immediately recognizable.
