What was the significance of the portrait of Baba that was being kept at Mirikar's house?

The portrait of Baba at Mirikar's house held special significance. According to Chapter 51, this photograph was deeply cherished by Megha, one of Baba's devoted disciples, who worshipped it as if it were Lord Shankar. The glass on the portrait had broken, so it was sent from Shirdi with Balasaheb to be repaired in Nagar. After the repairs were complete, it was kept covered in Mirikar’s drawing room, 'as if waiting for Dixit.' Its presence served as another element in the series of miraculous events, and Balasaheb ultimately entrusted it to Madhavrao for its safe return to Shirdi.
