Step 1: This is a factual recall from the poem "The Empty Heart."
Step 2: The poem's main character is a man consumed by his desire for wealth. He is granted seven pots of gold but his greed is not satisfied.
Step 3: The man's prayer to the wish-yielding tree was for a pot of 'gold'. The tree gave him seven. But his greed was so great that he worked himself to death trying to get enough wealth to fill an eighth pot, demonstrating the insatiable nature of his desire for gold.
