What does Chapter 25 tell us about the devotee Damu Anna and the story that is about to be told?

Towards the end of the chapter, Chapter 25 introduces a new narrative featuring a devotee named Damu Anna. We learn that he is a well-to-do person from Ahmednagar, specifically a wealthy Kasar (bronze-smith), who is deeply devoted to Sai Baba's feet. The text sets the stage for his story by promising it will be a demonstration of Sai's profound love for His devotees. Although the story is described as being "very short," it is also called "very pure in its meaning." The author of the Satcharitra promises that by listening to this story, one's mind will understand how the Guru-Mother, Sai, is an "Ocean of Mercy" and that their own difficulties will vanish.
