I heard Damu Anna was childless. Did Sai Baba help him with this issue?

Yes, the Shri Sai Satcharitra addresses this part of Damu Anna's life. Chapter 25 explicitly states that although Damu Anna had two wives, he did not have any children. The text confirms that through Sai Baba's grace and blessings, he was eventually blessed with the birth of sons. This particular event is presented as a clear example of how Sai grants the desired objects of His devotees and alleviates their suffering, illustrating the principle that one-pointed faith is met with divine grace and fulfillment.
