Could you narrate the story of Damu Anna's attempt to enter the cotton trade and the guidance he received from Sai Baba?

Certainly. The story, found in Chapter 25, begins with Damu Anna of Nagar writing a letter to Sai Baba, seeking His blessing for a speculative business venture. When the letter reached Shirdi, Shama presented it to Baba. In a display of His divine insight, Baba described the letter's contents—that Damu Anna was "trying to touch the sky"—before it was even read. After listening to the letter, Baba advised against the plan, sending the message: "Half a loaf of bread is enough for us; do not fall into the trap of millions." This reply crushed Damu Anna's hopes of becoming a millionaire. However, the letter also advised him to visit in person. Following this, Damu Anna traveled to Shirdi, where he sat at Baba's feet and massaged them, though he lacked the courage to bring up the business proposal again.
