The quote from Milan Kundera's "The Unbearable Lightness of Being" suggests that individual suffering pales in comparison to the shared pain experienced with and for others. It emphasizes the idea that empathy and solidarity amplify our understanding of pain, making it a collective burden rather than an isolated one. This shared experience allows for deeper connections and insights into human suffering.

Kundera also implies that our imaginations can intensify these feelings, as we reflect on the pain of others, thereby creating a cycle of empathy and echoing emotions. The horses of echoes represent the resounding effects of our collective suffering, illustrating how interconnected we are in our experiences. Ultimately, the quote highlights the significance of community and shared humanity in our emotional lives.
