How did Damu Anna react after receiving Sai Baba's advice about his business plans?

Damu Anna's reaction to Baba's advice was one of profound disappointment and regret. According to Chapter 25, upon reading the reply that advised against his cotton venture, Damu Shet was crestfallen. The text vividly describes his feelings, stating that the "fortress of his desires crumbled" and the "tree of hope was uprooted." He had been dreaming of earning a lakh, becoming a millionaire, and living happily. He felt that by writing the letter, he had caused his own harm and, in his own words, had "kicked away the served plate" that was right before his eyes.
