The quote by C.G. Jung highlights the duality of existence, emphasizing that light and shadow are interdependent. In this perspective, light represents clarity and positivity, while shadows symbolize darkness and uncertainty. The two elements coexist, shaping our understanding of reality. Without one, the other cannot exist, illustrating the balance that defines our experiences and emotions.

In Haruki Murakami's "1Q84," this theme resonates throughout the narrative, as the characters navigate their lives filled with both illumination and darkness. The interplay of light and shadow mirrors their struggles and aspirations, suggesting that understanding can only be achieved by acknowledging both sides of life. The story invites readers to reflect on this balance and the complexities it brings to the human experience.
