In Haruki Murakami's "South of the Border, West of the Sun," the author explores the concept of reality and its perception through a continuous interplay of different realities. To grasp one reality and deem it 'real,' we need to contrast it with another reality, leading us to further layers that complicate our understanding of existence.

This chain of realities within our consciousness reinforces our sense of self and presence. Each level relies on the existence of another, creating a complex web that sustains our feeling of being alive and aware in the world. Such reflections invite readers to consider the intricacies of existence and the subjective nature of reality.
