Describe the interaction between Sai Baba and the little girl named Amani as narrated in Chapter 29.

Chapter 29 introduces a heartwarming story to illustrate a point about Baba's grace. It describes a three-year-old girl named Amani who would approach Baba as he sat near the dhuni in the masjid. The chapter vividly paints a picture of the naked child holding an open tin box and asking Baba for 'rupees, rupees!' It highlights Baba's great affection for children; he would respond by giving Amani kisses, caressing her hair, and holding her close to his chest, even as the girl's mind was focused on the money.
