The subject of the conversation between the two sisters in the poem is the nature of true happiness and fulfillment.
Here's a breakdown:
* The Elder Sister: She represents a materialistic view of happiness. She desires wealth, land, and power, believing these will bring her contentment. She longs for a life of luxury and comfort.
* The Younger Sister: She represents a more spiritual view. She prioritizes love, kindness, and compassion. She believes true happiness lies in helping others and living a simple, meaningful life.
The poem uses the sisters' contrasting perspectives to explore the question: What truly matters in life? The poem ultimately suggests that true happiness comes not from material possessions but from living a life of love, kindness, and service to others.
