The statement from L.M. Montgomery's "Rilla of Ingleside" reflects the contrasting pace of physical and emotional development. The body, which matures steadily over time, symbolizes the gradual nature of physical growth. It embodies the everyday changes that come with age and experience, emphasizing patience and consistency in life’s journey.

In contrast, the soul's rapid and erratic growth signifies intense, transformative experiences that shape a person's inner self. These leaps signify moments of realization, emotional upheaval, and personal insight, suggesting that while our bodies may take their time to develop, our internal growth can be swift and deeply impactful.
