Can you explain the story behind the photograph of Sai Baba that was in Mirikar's drawing room?

The photograph of Sai Baba in Mirikar's drawing room had its own significant story, as detailed in Chapter 51. This particular portrait was deeply cherished by Megha, one of Baba's most devoted disciples, who worshipped it with great reverence, viewing it as a form of Lord Shankar. The glass on the photograph's frame had broken, so it was sent from Shirdi to Ahmednagar with Balasaheb Mirikar for repairs. After being fixed, it was kept in Mirikar's drawing room, covered with a cloth. The narrative suggests it was 'as if waiting for Dixit.' Balasaheb unveiled this sacred, newly-repaired portrait for Dixit to see right after Dixit and Madhavrao had finalized their plan to travel to Shirdi that very night.
