In the novel "Heart of Darkness," Joseph Conrad explores the theme of ownership and belonging through the protagonist’s reflections. The character perceives that while he possesses many things, the true concern lies in understanding to whom or what he is tied. This idea suggests a deeper existential question about identity and the influences that shape us.

Moreover, the reference to "powers of darkness" implies a struggle against malevolent forces that might claim one's soul. It highlights the conflict between civilization and savagery, prompting readers to consider the darker aspects of human nature and the unseen forces that govern our actions and thoughts.
