Who was Damu Anna and what were his acts of devotion mentioned in the text?

Damu Anna was a wealthy bronze-smith (Kasar) from Ahmednagar who is described in Chapter 25 as a devoted follower of Sai Baba. His devotion was demonstrated through his long-standing participation in the annual Ram Navami festival in Shirdi. As part of a vow he had taken, he provided one of the two large new flags for the procession each year, with the other being provided by the Nimonkars. The text also notes that after being childless despite having two wives, he was blessed with sons through Sai's grace, which is presented as another facet of his connection to Sai.
