How does the author frame the story of Damu Anna, and what larger point is it meant to illustrate about Sai Baba?

In Chapter 25, the author, Hemadpant, introduces the story of Damu Anna not just as a simple narrative, but as a powerful illustration of a core spiritual principle. He prefaces the tale by stating that when a devotee establishes "one-pointed faith," Sai Baba wards off all their misfortunes and removes their suffering. The story is presented as a "report that shows Sai's love for His devotees" and a way for the reader's mind to experience how the Guru-Mother is an "Ocean of Mercy." Therefore, Damu Anna's account is intentionally framed as proof of Sai's readiness to protect and bless those who are truly devoted to Him.
