The book mentions Damu Anna had a personal problem that Sai helped with. What was it?

According to the narrative in Chapter 25, Damu Anna's personal struggle was that he had no children, despite having two wives. This caused him distress, which was resolved through his faith in Sai Baba. The text explicitly states that by receiving Sai's blessings, Damu Anna's situation changed dramatically, and he was blessed with the birth of sons. This is presented as a testament to Sai's love and readiness to protect His devotees and grant their deeply held desires.
