A friend told me about Damu Shet wanting to make a lot of money and asking Baba for permission. What happened exactly?

Your friend is referring to the story of Damu Anna of Nagar, which is a powerful lesson on contentment. As recounted in Chapter 25, Damu Anna devised a business plan, likely in cotton, that he was certain would make him a millionaire. He wrote a letter to Sai Baba seeking his blessing and permission for this venture. However, Baba's response, delivered via Madhavrao, was to advise against it. Baba's message was clear: "what do you lack at home? Half a loaf of bread is enough for us; do not fall into the trap of millions." This reply completely shattered Damu Anna's dreams, leaving him very disappointed and feeling as though he had caused his own misfortune by even asking.
