Could you explain Damu Anna's specific involvement in the Ram Navami festival in Shirdi?

Damu Anna played a significant role in the annual Ram Navami festival held in Shirdi. According to Chapter 25, he had taken a regular vow, which he upheld for many years with great love and devotion, to provide one of the two large new flags for the festival's procession. The other flag was provided by the Nimonkars. This procession, which featured musical instruments, would begin at the house of Kondaji Sutara and conclude with the two long banners being tied to the ends of the Masjid, demonstrating Damu Anna's committed and public display of his faith.
