In Haruki Murakami's "Kafka on the Shore," the idea that everything in existence is in a state of constant change is vividly captured. The author emphasizes that various aspects of life—including the Earth, time, and human emotions—are not fixed; instead, they evolve and transform continuously. This notion illustrates the dynamic nature of reality, where nothing remains stagnant or immutable.

This perspective invites readers to embrace the fluidity of existence and recognize that change is an intrinsic part of the universe. By likening the universe to a "big FedEx box," Murakami suggests that life is characterized by movement and transition, where each moment brings new experiences and revelations. The quote encapsulates a central theme in the novel: the acceptance of change as a fundamental truth of life.
