Based on the provided excerpts, what are the central themes and narratives presented in Chapter 29 of the Sai Satcharitra?

The provided excerpts from Chapter 29 of the Sai Satcharitra focus on the central theme of Sai Baba's incomprehensible wisdom, particularly as expressed through his acts of charity. The narrative begins by establishing his fame for being generous and compassionate, which attracted a group of devotees from Madras on their way to a pilgrimage. A key theme developed in this chapter is the unpredictability of Baba's grace; while he gave money abundantly, it was not guaranteed for everyone. The text explains that receiving his gift was a matter of fortune. To further illustrate this point, the chapter introduces a story about a little girl named Amani who would directly ask Baba for rupees, showcasing his affectionate nature towards children.
