In "The Sheltering Sky," Paul Bowles explores the uncertainty of the future, emphasizing that it is inherently unpredictable. The quote suggests that while we may try to envision what lies ahead, there are always multiple paths one might take, leading to various outcomes. This inherent ambiguity reflects the complexities of life and the choices we face.

The narrative delves into themes of exploration and existential questioning, with characters confronting their destinies in an unfamiliar land. The idea that there is no definitive knowledge about what tomorrow holds reinforces a central message: life is a journey filled with potential and ambiguity, leaving room for unexpected developments.
