Can you tell me about Damu Anna's background and his connection to the Ram Navami festival?

Damu Anna was a wealthy bronze-smith, or Kasar, from Ahmednagar who was a devoted follower of Sai Baba. Chapter 25 introduces him as a great devotee whose story demonstrates Sai's readiness to protect His followers. His significant connection to the Ram Navami festival in Shirdi was a long-standing vow he maintained with uninterrupted devotion. Each year, he provided one of the two large new flags that were taken out in a procession through the village. The other flag was provided by the Nimonkars. This annual tradition was a testament to his deep faith, and the text also notes that after being childless with two wives, he was blessed with sons through Sai's grace.
