Can you explain the story behind the photograph of Sai Baba that was shown to Dixit at Mirikar's house?

The photograph of Sai Baba shown to Dixit had a special history, as explained in Chapter 51. This particular portrait was deeply cherished by Megha, a devoted disciple who worshipped it with great love, viewing it as a form of Lord Shankar. The glass covering the photograph had broken, so it was sent from Shirdi with Balasaheb Mirikar to Ahmednagar to be repaired. After the repairs were completed, the portrait was kept covered in Mirikar's drawing room. The text poetically states it was 'as if waiting for Dixit.' Its unveiling after Dixit's travel plans were confirmed with Madhavrao served as a powerful symbol of Baba's blessing on the entire arrangement.
