Final answer:
Edna is realizing that independence and self-discovery can lead to a significant sense of solitude. Various excerpts depict characters wrestling with loneliness, the search for meaning, and the intricacies of independence.
Step-by-step explanation:
Edna's realizations reflect a complex understanding of her self-discovery and independence, often accompanied by a profound sense of solitude. The excerpts you have provided suggest that the characters within their narratives are grappling with feelings of loneliness, a quest for purpose, and the challenges of self-reliance. We see themes of independence leading to an understanding that such freedom can also bring about a great sense of solitude. This sentiment is echoed across different contexts, whether it be living alone, facing life after dedicated service to family, or separation from a spouse.
While international solutions or the completeness of being alone as true happiness are noted, they are not conclusively presented as Edna's realization. Rather, the underlying theme is the recognition of self-sufficiency's double-edged sword - offering enlightenment and isolation.
