What specific advice did Sai Baba send back to Damu Anna about his business plans, and what was the immediate effect on Damu Anna?

In Chapter 25, after listening to Damu Anna's letter, Sai Baba declared that the "Shet's mind has gone astray!" His dictated reply was a powerful lesson in contentment: "Half a loaf of bread is enough for us; do not fall into the trap of millions." Upon receiving this counsel, Damu Anna was immediately crestfallen and deeply disappointed. The narrative describes how the "fortress of his desires crumbled" and the "tree of hope was uprooted." He had envisioned becoming a millionaire, and Baba's advice shattered this worldly ambition, making him feel he had personally kicked away a great opportunity.
