Can you recount the story of how the author received Sai Baba's portrait, as detailed in Chapter 41?

Chapter 41 explains the miraculous arrival of a physical portrait of Sai Baba. The narrator recalls a dream where Sai promised, "On a Holi festival day, I am coming to your house for a meal today." The chapter then introduces a story told by a man named Alli Mohammed. He had purchased a beautiful portrait of Sai in Mumbai that particularly appealed to him. As described in Chapter 41, it was Alli Mohammed who, on that exact Holi festival day, arrived with this very portrait just as the author was about to sit for lunch, thus fulfilling Sai's dream-promise in an unexpected and delightful way.
