How did Damu Anna react to Sai Baba's discouraging reply about his business aspirations?

Damu Anna's reaction to Sai Baba's reply was one of profound disappointment and regret. According to Chapter 25, upon reading the advice not to fall into the trap of millions, Damu Shet was crestfallen. The text vividly describes that the "fortress of his desires crumbled; the tree of hope was uprooted." He lamented the lost opportunity, imagining how he could have become a millionaire money-lender. He felt he had caused his own harm by writing the letter, comparing it to kicking away a served plate that was right before his eyes.
