How does the author of the Sai Satcharitra frame the story of Damu Anna to illustrate a broader spiritual message?

The author uses the story of Damu Anna in Chapter 25 as a powerful illustration of a core spiritual principle: the efficacy of unwavering faith. Before even beginning the tale, the author asserts that once one-pointed faith is established, Sai removes all of a devotee's misfortunes and grants their desires. Damu Anna's story is then presented as a report that shows Sai's love for His devotees and how the "Guru-Mother is an 'Ocean of Mercy.'" By mentioning that Damu Anna was blessed with sons after being childless, the narrative is explicitly framed not just as a story, but as evidence of Sai's power to transform a devotee's life in response to their faith.
