The quote "Even stone can be worn down with enough rain," from Arthur Golden's "Memoirs of a Geisha," serves as a metaphor for perseverance and resilience. It illustrates how continuous effort and patience can lead to significant changes, even in the hardest of materials. This idea reflects the journey of the protagonist, who faces numerous challenges yet ultimately evolves through her experiences.

This statement highlights the power of time and persistence in shaping outcomes. Just as stones are gradually worn away by relentless rain, individuals can overcome obstacles and transform their circumstances by consistently addressing their struggles. It symbolizes hope and the potential for personal growth despite difficulties.
