Can you tell me about Damu Anna? Who was he and what was his relationship with Sai Baba?

Damu Anna, also known as Damu Anna Kasar, was a wealthy bronze-smith from Ahmednagar who was deeply devoted to Sai Baba. Chapter 25 introduces him as a great devotee whose story illustrates Sai's protective love. His faith was so strong that he was a key participant in the annual Ram Navami festival in Shirdi, where he had a long-standing vow to provide one of the two large flags for the procession. The text further notes a significant blessing he received: though he had two wives, he was childless, and it was only through Sai Baba's grace that he was eventually blessed with sons. His story is presented as a testament to how Sai wards off misfortunes for those with one-pointed faith.
