The quote reflects the deep interconnection between light and darkness, symbolizing the essential balance of dualities in human nature. A man devoid of a shadow is depicted as lacking a soul, suggesting that our darker aspects are intrinsic to our identity and humanity. This evokes the idea that all individuals possess both good and evil traits, which contribute to a complete existence.

Moreover, a shadow without a man is portrayed as incomplete and forlorn, highlighting the importance of the individual in giving meaning to darkness. Yolen's words signify that light and dark should coexist harmoniously, as they shape the essence of life. Together, they create a unified whole, reminding us that our complexities make us who we are.
