I read about a photograph of Baba being repaired. What is the story behind this portrait and its connection to Dixit's visit?

Chapter 51 recounts the story of a specific photograph of Sai Baba. This portrait was deeply cherished and worshipped by Megha, a devoted disciple, who regarded it as Lord Shankar. The glass on the photograph had broken, so it was sent from Shirdi to Nagar with Balasaheb for repairs. After being fixed, the portrait was kept covered in Mirikar's drawing room, described as if it were waiting for Dixit. Once Dixit's travel plans with Madhavrao were settled, Balasaheb unveiled the portrait and entrusted it to Madhavrao, linking this sacred object to the events surrounding Dixit's trip.
