I heard Damu Anna was childless. Can you tell me what the Satcharitra says about Sai Baba helping him with this issue?

Yes, the source text confirms that Sai Baba helped Damu Anna with his desire for children. Chapter 25 of the Shri Sai Satcharitra explicitly states that Damu Anna had two wives but remained childless. It was only after receiving Sai Baba's blessings that he was finally blessed with sons. This particular detail is shared to illustrate a key theme: that Sai wards off the misfortunes of His devotees, grants their desired objects, and removes their suffering. The author presents this as an example of Sai's readiness to protect His followers and as proof that the 'Guru-Mother is an Ocean of Mercy.'
