Can you tell me about Damu Anna and his connection to Sai Baba?

Damu Anna was a wealthy bronze-smith, or Kasar, from Ahmednagar who was a devout follower of Sai Baba. Chapter 25 describes him as a great devotee who demonstrated his faith in several ways. He had a long-standing vow to provide one of the two large flags for the annual Ram Navami festival procession in Shirdi, a duty he performed with great love for many years. The chapter also highlights a personal miracle in his life; though he had two wives, he was childless. After receiving Sai Baba's blessings, he was blessed with sons, which serves as a prime example of how Sai grants the desires of His faithful devotees.
