What personal hardship did Damu Anna face, and how was it resolved through his faith in Sai?

The Shri Sai Satcharitra details a significant personal hardship faced by Damu Anna. Chapter 25 reveals that despite having two wives, he had no children. This lack of an heir was a source of suffering for him. The text explains that this situation was resolved by receiving Sai Baba's blessings, after which he was blessed with sons. This outcome is presented as a direct result of his devotion and serves as a testament to the principle that Sai grants the desired objects of His devotees and removes their suffering once they establish one-pointed faith in Him.
