How did Damu Anna's devotion to Sai Baba manifest, and what were the results of his faith according to the Satcharitra?

Damu Anna, a wealthy devotee from Ahmednagar, demonstrated his faith in a very public and consistent manner. As described in Chapter 25, he upheld a regular vow for many years to provide one of the two large new flags for the annual Ram Navami festival procession in Shirdi. This was an act of uninterrupted love and devotion. The result of his faith was profound; the text notes that while he had two wives, he was childless. After receiving Sai Baba's blessings, a testament to Sai's love for his devotees, Damu Anna was blessed with sons, showing how Sai grants the desired objects of his followers.
