Why was Damu Anna so devastated after receiving Sai Baba's reply to his letter?

Damu Anna was devastated by Baba's reply because it directly thwarted his ambitious financial plans. Chapter 25 reveals that Damu Anna had fantasized about a lucrative venture, dreaming, "I would have earned one lakh now, and put half a lakh on interest. I would have immediately become a millionaire money-lender and lived happily in Nagar." Baba's advice to be content with "half a loaf of bread" and avoid the "trap of millions" caused the "fortress of his desires" to crumble. He was crestfallen, believing he had foolishly kicked away a served plate and caused his own harm by seeking Baba's counsel in the first place.
