Describe how Damu Anna's personal life was transformed by Sai Baba's grace, based on the details provided.

The narrative in Chapter 25 presents Damu Anna's story as a prime example of Sai Baba's power to remove suffering and grant the desires of his devotees. The text explicitly states that Damu Anna had two wives but remained childless, a significant personal misfortune. However, by receiving Sai's blessings, his situation was completely transformed, and he was blessed with sons. This event is cited as direct evidence of Sai's readiness to protect His devotees and shows how the Guru-Mother acts as an "Ocean of Mercy." The story serves to demonstrate how one-pointed faith in Sai can lead to the resolution of profound personal difficulties.
