In Haruki Murakami's "Kafka on the Shore," the narrative emphasizes the permanence of certain memories in our lives. Despite the inexorable passage of time and various experiences that come and go, there are aspects of our past that remain indelible. The line captures the essence of how significant moments or emotions shape our identity and can linger in our minds forever.

This idea suggests that some memories hold such weight that they defy the natural tendency toward forgetfulness. They become intertwined with who we are, influencing our thoughts, feelings, and actions, illuminating the power of the past in the present. Murakami's exploration of these themes invites readers to reflect on their own experiences and the lasting impact of their memories.
