Who is Damu Anna, and why is his story introduced in Chapter 25?

According to the information in Chapter 25, Damu Anna was a well-to-do person from Ahmednagar who belonged to the Kasar (bronze-smith) community. He is described as being wealthy and, more importantly, a devotee who was devoted to Sai's feet. The chapter introduces his story as an example or "report that shows Sai's love for His devotees." The narrative explicitly states that this story is being told to demonstrate how "once one-pointed faith is established, Sai wards off all the misfortunes of that devotee" and grants their desired objects. Therefore, as explained in Chapter 25, Damu Anna's story serves as a practical illustration of the power of faith in Sai Baba.
