How did Damu Anna react when he received Baba's discouraging response about the cotton business?

Upon receiving Sai Baba's reply, Damu Anna was utterly devastated and crestfallen. Chapter 25 vividly describes his disappointment, stating that the 'fortress of his desires crumbled' and the 'tree of hope was uprooted.' He had been dreaming of earning a lakh, putting half on interest, and becoming a millionaire money-lender in Nagar. Baba's words shattered this vision, causing the 'kingdom of the mind that he had built' to melt away. He felt he had made a mistake by writing the letter, believing he had personally kicked away a served plate and caused his own harm.
