How does the story of Damu Anna illustrate Sai Baba's mercy and power?

The story of Damu Anna is presented in Chapter 25 as a prime example of Sai Baba's role as an 'Ocean of Mercy.' Damu Anna, a wealthy and devoted follower, had a significant sorrow in his life: despite having two wives, he remained childless. The narrative explicitly states that 'By receiving Sai's blessings, he was blessed with sons.' This miracle directly demonstrates Sai's power to grant the desires of his devotees and remove their suffering. The author uses this short but meaningful story to prove the earlier assertion that once a devotee establishes one-pointed faith, Sai Baba actively wards off their misfortunes. Thus, Damu Anna's experience of being blessed with children serves as powerful evidence of Sai's divine intervention and boundless compassion for those who are devoted to him.
