How does Chapter 41 connect the story of Alli Mohammed's photo to the author's previous experience on Holi festival day?

Chapter 41 masterfully links two significant events, revealing a divine plan. The chapter begins by referencing a previous narration where Sai Baba appeared in a dream, promising the author, "On a Holi festival day, I am coming to your house for a meal today." This dream fulfilled a heartfelt desire. Chapter 41 then introduces the story of Alli Mohammed to explain how this promise was physically manifested. It clarifies that the physical portrait of Sai Baba, which Alli Mohammed had purchased in Mumbai, was the very object he brought to the author's house "at that very peak moment" just as they were about to sit for the Holi lunch. This chapter reveals that Alli's arrival with the photo was the unexpected and miraculous fulfillment of Baba's dream-promise, showcasing Sai's divine play (Leela).
