Can you tell me more about the special portrait of Sai Baba that was at Mirikar's house?

The portrait of Sai Baba at Mirikar's house held special significance and appeared at a pivotal moment for Dixit. Chapter 51 describes that after Dixit's travel plans were settled, Balasaheb Mirikar unveiled this photograph. This particular portrait was deeply cherished by Megha, a devoted disciple of Baba, who used to worship it with great love as if it were Lord Shankar himself. The portrait had been sent from Shirdi to Ahmednagar with Balasaheb for repairs because its glass had broken. After being repaired, it was kept covered in the Mirikar's drawing room, seemingly waiting for Dixit to have its darshan before he departed for Shirdi, adding to the miraculous nature of the events surrounding his journey.
