Can you explain the story of how Alli Mohammed acquired the portrait of Sai Baba?

According to his own account in Chapter 41, Alli Mohammed's acquisition of the Sai Baba portrait was a chance encounter. One day, while wandering the streets in Mumbai, he came across a merchant selling various beautiful pictures of saints, sages, and holy men. As he looked through the collection, one particular portrait appealed to his heart more than any other. Recognizing the image as his own worshipped deity, Sai Baba, he felt an eagerness to possess it. He promptly paid the cash price, brought the portrait home, and hung it on his wall, taking daily Darshan with great love and joy for three months before it was eventually passed on.
