In "The Blue Castle" by L.M. Montgomery, the protagonist undergoes a significant transformation. She sheds the burdens of her past, which include old habits, inhibitions, and the weight of previous experiences. This act of brushing away the remnants of her former self symbolizes a desire for liberation and personal growth.

Metaphorically comparing her past to dead leaves, the character seeks to cleanse her life of negativity and restrictions. This process represents a renewal and a stepping into a new chapter, highlighting themes of self-discovery and the importance of letting go to embrace a more fulfilling existence.
