What was Sai Baba's advice to Damu Anna regarding his plan to earn millions, and how did Damu Anna react?

When Damu Anna wrote to Sai Baba about a business venture, Baba's advice was one of caution and contentment. As detailed in Chapter 25, Baba instructed Shama to reply, "Half a loaf of bread is enough for us; do not fall into the trap of millions." Upon receiving this reply, Damu Anna was deeply disappointed. The text states that the "fortress of his desires crumbled" and he became very crestfallen, feeling that he had caused his own harm by writing the letter and had, in his own words, "kicked away the served plate myself."
