According to Chapter 29, what was the underlying principle of Sai Baba's charity and why didn't he give money to everyone?

Chapter 29 explains that while Sai Baba was known for his generous distribution of money, his charity was not indiscriminate. The chapter makes it clear that "he did not give to everyone - no one knew his mind." Though he was merciful and many beggars and alms-seekers came to his door, he did not give to all of them alike. The profound principle suggested in Chapter 29 is that receiving a blessing from him was a matter of spiritual timing and fortune. The text states that this blessing was bestowed only upon those for whom the "auspicious time had arrived," describing the touch of a saint's hand as a "shell of fortune" obtained only by the fortunate, indicating a deeper spiritual mechanism at play.
