Could you tell me about Damu Anna from Ahmednagar and his relationship with Sai Baba?

Damu Anna was a well-to-do, wealthy Kasar (bronze-smith) from Ahmednagar who was deeply devoted to Sai Baba. As described in Chapter 25, he is referred to as a "great devotee" who was devoted to Sai's feet. His devotion was demonstrated through a long-standing vow to provide one of the two large flags for the annual Ram Navami festival procession in Shirdi. Furthermore, his relationship with Sai was one of a devotee receiving profound grace; having been childless despite having two wives, Damu Anna was blessed with sons after receiving Sai's blessings. This story illustrates Sai's readiness to protect and provide for His devotees.
