How does the story of Damu Anna serve to illustrate Sai Baba's power and compassion?

The narrative of Damu Anna in Chapter 25 is presented as a clear illustration of Sai Baba's divine power and compassion for His followers. The text states that the story shows how Sai wards off the misfortunes of a devotee once one-pointed faith is established. The specific example given is that Damu Anna, who had no children, was blessed with sons through Sai's grace.
