The quote reflects on the struggles of civilizations throughout history, highlighting that their challenges are not unique but rather part of a common human experience.

It underscores the empathy that arises in the face of suffering, as well as the acknowledgment that every civilization has its own path filled with obstacles and prevailing hope.
