The quote reflects the impact of a girl's beauty on the speaker, illustrating how something as small as a polished stone can evoke profound emotions. It suggests that despite the complexity and depths of his heart, her beauty penetrates deeply, reaching places he thought were untouched. The imagery of the stone sinking symbolizes deep feelings that resonate within him.

This moment highlights the power of connection and the vulnerability that accompanies attraction. The girl's beauty serves as a catalyst for introspection, prompting the speaker to confront his emotions. Through Murakami's poetic language, we see how love and admiration can profoundly affect an individual's inner world.
