From the author's perspective, what is the purpose of including the story of Damu Anna in the Shri Sai Satcharitra?

The author includes the story of Damu Anna to serve as a powerful and concrete example of Sai Baba's protective love and mercy towards His followers. Chapter 25 introduces this narrative by establishing a core principle: once a devotee develops "one-pointed faith," Sai Baba actively works to ward off their misfortunes and grant their desires. The tale of Damu Anna, a wealthy but childless devotee who was blessed with sons through Sai's grace, is presented as a "report that shows Sai's love for His devotees." The author intends for the reader's mind to experience how the Guru is an "Ocean of Mercy" and to find hope that their own difficulties might also vanish by hearing this pure story.
