How did Damu Anna react after receiving Sai Baba's discouraging response to his business proposal?

Damu Anna was utterly devastated by Sai Baba's reply. The source material in Chapter 25 vividly describes his reaction, stating that upon reading the response, "The fortress of his desires crumbled; the tree of hope was uprooted." He had been fantasizing about earning a lakh, becoming a millionaire money-lender, and living happily. Baba's refusal shattered these dreams instantly, leaving him very crestfallen. He lamented his decision to even write the letter, feeling he had personally "kicked away the served plate" and caused his own misfortune.
