What is the story behind the arrival of Sai Baba's portrait as described in Chapter 41?

Chapter 41 recounts the story of how a physical portrait of Sai Baba arrived unexpectedly. The narrative is told by Alli Mohammed, who explains that one day in Mumbai, while wandering the streets, he saw a merchant selling various pictures of saints and holy men. As described in the chapter, he was immediately drawn to one particular portrait of Sai Baba, which he felt was more attractive than all the others. Since Sai was already his worshipped deity, he eagerly paid the price, brought the portrait home, and hung it on his wall, taking daily Darshan with great love. This story is presented as a humorous and clear divine play, or Leela, of Sai Baba.
