What personal struggle did Damu Anna have, and how does his story illustrate Sai's power to help devotees?

Chapter 25 reveals that the wealthy and devoted Damu Anna faced a significant personal struggle: he had two wives but remained childless. The text serves as a testament to Sai's grace by stating, "By receiving Sai's blessings, he was blessed with sons." This outcome is presented as a direct result of his faith and Sai's mercy. The narrative is used to support the earlier assertion in the chapter that once a devotee establishes one-pointed faith, Sai wards off their misfortunes, removes their suffering, and grants them their desired objects, showing how the Guru-Mother is an "Ocean of Mercy."
