Who is Damu Anna as introduced in Chapter 25, and what does the chapter promise about his story?

Chapter 25 introduces Damu Anna as a well-to-do and wealthy Kasar (bronze-smith) from Ahmednagar who was a devoted follower at Sai's feet. The chapter does not narrate his full story but sets the stage for it. It is presented as a forthcoming report that will demonstrate Sai's profound love for His devotees. The text promises that listening to this "novel story" will fill the listeners' hearts with joy and show how the Guru-Mother is an "Ocean of Mercy." Though the story is described as being very short, it is said to be pure in its meaning and will help one's difficulties vanish.
