What was Sai Baba's advice to Damu Anna regarding his desire to enter the cotton trade, and how did Damu Anna react?

When Damu Anna of Nagar wrote to Sai Baba about his plan to enter a trade for immense profit, Baba advised strongly against it. As recorded in Chapter 25, after having the letter read by Madhavrao, Baba said, "The Shet's mind has gone astray!" He instructed Shama to reply with the message, "what do you lack at home? Half a loaf of bread is enough for us; do not fall into the trap of millions." Upon reading this reply, Damu Anna was extremely disappointed and crestfallen. The text states that "The fortress of his desires crumbled; the tree of hope was uprooted." He lamented his decision to write the letter, feeling he had kicked away a golden opportunity.
