Who is Damu Anna, and what does Chapter 25 promise about his story?

As introduced in Chapter 25, Damu Anna was a well-to-do, wealthy Kasar (bronze-smith) from Ahmednagar and a devoted follower of Sai Baba. The chapter sets up his story as an example of Sai's love for His devotees and how He helps those with one-pointed faith. The text promises that by listening to this "novel story" with reverence, listeners' hearts will be filled with joy. It is presented as a very short but pure tale that will demonstrate how the Guru-Mother is an "Ocean of Mercy" and help make the listeners' own difficulties vanish.
