Final answer:
Dorothy seeks abundance by relating to the poor and facing challenges, finding fulfillment not in material wealth but in emotional and spiritual growth, culminating in a simple yet profound domestic happiness.
Step-by-step explanation:
At first, Dorothy seeks an abundant life by grappling with her own poverty and comparing her situation with those even less fortunate. Her journey through hardship, where she witnesses and interacts with the impoverished, including a woman who reminds her of their shared roots and children begging untruthfully, represents her search for meaning and fulfillment. Initially, Dorothy seems to feel a blend of kinship, fear, and moral ambiguity towards the impoverished, indicative of her and her brother William's identification with being poor yet spiritually rich.
However, the ultimate realization of Dorothy's quest for an abundant life comes not through material wealth, but through the emotional and spiritual growth that she experiences. This is highlighted by her moment of charity to the woman who grew up in her hometown and by facing the storm with newfound courage, inspired by the perseverance of the daffodils. The fulfillment she seeks is partially attained by the simple, yet profound, reward of spending a cozy evening by the fire with her brother - a happy ending that comes from within rather than external circumstances.
