Summary
This quote suggests that time passes by quickly, but it has a lasting impact on our lives. While we may not notice the actual passage of time, its influence and consequences are always present. The "shadow" left behind refers to the profound effects, memories, and experiences that time leaves imprinted on us. Even though we may not realize it at the moment, the choices we make and the moments we live create a significant impact that lingers beyond the fleeting nature of time itself.
