What is the main story introduced in Chapter 41, and how does it connect to a previous event?

Chapter 41 narrates a miraculous story about how a physical portrait of Sai Baba arrived unexpectedly. This event is linked to a previous story, mentioned earlier in the Satcharitra, where Sai appeared in a dream promising, "On a Holi festival day, I am coming to your house for a meal today." As detailed in Chapter 41, the arrival of the photo, brought by a man named Alli Mohammed, fulfilled this dream-promise at the exact right time, delighting the narrator just as they were about to have their Holi lunch. This chapter explains how that specific image came to be delivered at that precise, miraculous moment.
