What are the main teachings and stories introduced in Chapter 29 of the Sai Satcharitra?

Chapter 29 of the Sai Satcharitra primarily focuses on the generous yet inscrutable nature of Sai Baba's charity. It begins by recounting the story of a group of devotees from Madras who, having heard of Baba's fame for giving money, stopped in Shirdi during a pilgrimage. The chapter emphasizes that Baba was compassionate and distributed money abundantly and daily, not just on special occasions. However, it also introduces the key theme that his charity was unpredictable; he did not give to everyone who asked. To illustrate this, the chapter sets up a story about a three-year-old girl named Amani who would regularly ask Baba for rupees, highlighting his affection for children while building suspense around his unpredictable nature of giving, which is described as a blessing for the fortunate.
