In Franz Kafka's "Letters to Milena," the author explores his feelings of inner turmoil and the obsession with cleanliness as a reflection of his moral and emotional state. He conveys a deep sense of being 'dirty,' which symbolizes his struggles and imperfections. This preoccupation with cleanliness serves as a coping mechanism, revealing his desire for redemption and purity in a world that often feels tainted.

Kafka further contrasts the concept of purity with the idea that the most profound expressions of beauty can arise from suffering and darkness. He suggests that those who endure the deepest pain, represented by the inhabitants of hell, possess a unique clarity in their expression that can resonate like angelic music. This duality highlights the complexity of human experience, where moments of despair can yield profound insights and artistic beauty.
