Can you tell me about the Sai Baba portrait that Dixit saw at Mirikar's house? What's its backstory?

The portrait of Sai Baba that H.S. Dixit encountered had its own special history. As recounted in Chapter 51, this specific photograph was deeply cherished by Megha, one of Baba's most devoted disciples, who worshipped it with great reverence as if it were Lord Shankar. The glass of the portrait had broken, so it had been sent from Shirdi with Balasaheb Mirikar to be repaired in Ahmednagar. After the repairs were completed, the portrait was kept covered in Mirikar’s drawing room. The text suggests it was almost as if it was waiting there for Dixit. After Dixit and Madhavrao finalized their travel plans, Balasaheb Mirikar unveiled it and then entrusted the repaired portrait to Madhavrao to be taken back to Shirdi, creating another poignant moment in Dixit's journey.
