What is the underlying lesson that Chapter 29 aims to convey through its stories about Sai Baba's charity?

The central theme of Chapter 29, as revealed through its narratives, is the incomprehensible and sovereign nature of Sai Baba's grace, particularly expressed through his charity. The chapter begins by describing his immense generosity, attracting devotees from far away. However, it quickly pivots to explain that this generosity was not a simple transaction. The text states, 'he did not give to everyone - no one knew his mind,' and introduces the concept that receiving a blessing was dependent on one's 'auspicious time.' The story of the little girl Amani is presented specifically to 'convey the meaning of this,' illustrating that while Baba's compassion was boundless, the manifestation of his material grace was a mysterious and fortunate event.
