How did Damu Anna react to Sai Baba's discouraging reply about his business venture, and what were his specific financial aspirations?

Upon receiving Sai Baba's reply, Damu Anna was utterly crestfallen and disappointed. The narrative in Chapter 25 describes his feelings vividly: "The fortress of his desires crumbled; the tree of hope was uprooted." He felt he had caused his own harm by even writing the letter. His specific aspiration was to earn one lakh from the cotton trade, put half a lakh on interest, and instantly become a millionaire money-lender in Nagar. Baba's cautionary advice completely melted away this "kingdom of the mind" he had constructed, leaving him to lament the perceived loss.
