What is the story behind the portrait of Sai Baba that was kept at Mirikar's house?

The portrait of Sai Baba at Mirikar's house had its own special history, as mentioned in Chapter 51. This photograph was originally worshipped with great devotion by Megha, who regarded it as Lord Shankar. The glass on the portrait had broken, which is why it was sent from Shirdi with Balasaheb Mirikar to be repaired in Ahmednagar. After the repairs were complete, the portrait was kept covered in Mirikar's drawing room. The narrative suggests it was almost waiting for H.S. Dixit's arrival. After Dixit's travel plans with Madhavrao were confirmed, Balasaheb revealed the portrait, which he then entrusted to Madhavrao to take back.
