Who was the devotee disappointed by Sai Baba's advice, and what were the specific financial ambitions that were thwarted?

The devotee who was left disappointed was Damu Anna, also called Damu Shet of Nagar. As detailed in Chapter 25, he had written to Baba seeking permission for a business venture. After receiving Baba's discouraging reply, Damu Anna was crestfallen because his grand financial ambitions were shattered. He had been planning a deal where he believed he would earn one lakh, put half a lakh on interest, and 'immediately become a millionaire money-lender.' Baba's advice to be content with half a loaf of bread caused the 'fortress of his desires' to crumble completely.
