The source mentions Damu Anna was blessed with sons. Can you explain the circumstances surrounding this event?

The narrative in Chapter 25 explains that Damu Anna, a devoted follower of Sai, had two wives but was without any children. His story is used to illustrate the principle that Sai Baba grants the desired objects of His devotees and removes their suffering. The text explicitly states that "By receiving Sai's blessings, he was blessed with sons." This event is portrayed as a direct result of Sai's grace and a testament to Sai's readiness to protect and help His followers who maintain one-pointed faith, showcasing how the Guru-Mother is an "Ocean of Mercy."
