The text mentions Damu Anna had personal struggles. What were they, and how did Sai Baba's grace affect his family life?

According to Chapter 25, Damu Anna, despite being a wealthy merchant and having two wives, was initially without children. This lack of an heir was a significant personal issue for him. However, the text clearly states that his devotion was rewarded with divine intervention. It is mentioned that "By receiving Sai's blessings, he was blessed with sons." This detail is presented as a testament to Sai's power to grant the desired objects of His devotees and remove their suffering, illustrating that Sai's grace directly and positively impacted Damu Anna's family life by fulfilling his desire for children.
