Why is the story of Damu Anna included in the Shri Sai Satcharitra?

The story of Damu Anna is included in the Shri Sai Satcharitra to illustrate a core principle: Sai Baba's immense love and protective nature towards his devotees. As Chapter 25 introduces the tale, it states that once one-pointed faith is established, Sai wards off all misfortunes and grants the desired objects of His followers. Damu Anna's story, though described as short, is presented as a pure and novel account to show how the 'Guru-Mother' is an 'Ocean of Mercy.' By listening to this report, the text promises that the listeners' hearts will be filled with joy and their own difficulties will vanish.
