I read something about a photograph of Sai Baba in Ahmednagar. What was its story and why was it there?

The photograph of Sai Baba has an interesting backstory within this episode. Chapter 51 explains that this specific portrait was deeply cherished and worshipped by Megha, a devoted disciple. The glass on the frame had broken, so the photo had been sent from Shirdi with Balasaheb Mirikar to be repaired in Ahmednagar. After the repair, the portrait was kept covered in Mirikar's drawing room, described as if it were "waiting for Dixit." Once Dixit and Madhavrao's plan to travel was settled, Balasaheb unveiled the portrait and entrusted it to Madhavrao to be taken back to Shirdi, as Balasaheb was staying in Nagar longer for a horse show.
