Using the provided text, give an example of how Sai Baba granted the desires of a devotee who showed unwavering faith.

A prominent example of Sai Baba granting a devotee's desire is the case of Damu Anna, a wealthy follower from Ahmednagar. As recounted in Chapter 25, Damu Anna had two wives but was afflicted with the suffering of being childless. Because of his one-pointed faith and devotion, which included a vow to provide a flag for the Ram Navami festival annually, he received Sai's blessings. Consequently, his misfortune was removed, and he was blessed with the birth of sons. This story serves as a clear illustration of the principle that Sai grants the desired objects of His faithful devotees.
