I heard Damu Anna was childless. How did Sai Baba help him with this problem?

Yes, the Shri Sai Satcharitra confirms that Damu Anna faced the personal suffering of being childless. Chapter 25 explicitly states that "Damu Anna had two wives, but he had no children." His predicament was resolved through divine grace. The text explains, "By receiving Sai's blessings, he was blessed with sons." This event is presented as a prime example of a core teaching in the book: when a devotee establishes one-pointed faith, Sai Baba wards off their misfortunes, removes their suffering, and grants their desired objects. Damu Anna's story serves as a testament to this principle.
