In Saul Bellow's "Henderson the Rain King," the protagonist wrestles with profound personal struggles and the desire for transformation. He questions whether retreating to the desert would help him purge his inner turmoil, symbolized by the 'devil' within him. This yearning for solitude reflects his belief that he might need to isolate himself to achieve a clearer understanding of himself before engaging with others.

The metaphor of the desert indicates a quest for clarity and renewal. Henderson acknowledges that he is not yet ready to face society, suggesting a deep introspection that he hopes will lead to healing. His longing for the desert underscores the idea that self-discovery often requires solitude and reflection to confront one's internal conflicts.
