The Moroccan proverb highlights the contrast between two different types of reeds that share the same water source. One reed is hollow, signifying emptiness or lack of substance, while the other, sugarcane, represents sweetness and richness. This imagery invites reflection on how individuals or entities can thrive differently even when they have similar resources available to them. It suggests that one's qualities or characteristics greatly influence the results of their circumstances.

Tahir Shah's book, "The Caliph's House: A Year in Casablanca," explores the complexities of Moroccan culture and lifestyle. Through this proverb, Shah may be emphasizing the idea that it is not just the resources one accesses that determine success or fulfillment; rather, it is also the inherent qualities—such as resilience, creativity, or perspective—that shape one's experience and outcomes in life. Thus, the wisdom in this saying encourages introspection about the nature of one's own existence and influence.
