What underlying spiritual principle governed Sai Baba's charity, according to the philosophy presented in Chapter 29?

Chapter 29 suggests that Sai Baba's charity was not governed by simple human logic but by a profound and inscrutable spiritual principle. The text emphasizes that his distribution of money was an expression of his 'incomprehensible wisdom.' It wasn't a consistent welfare system, as he did not give to all beggars or alms-seekers. Instead, the act of receiving money from him was a sign of divine grace. The chapter poetically states that this blessing was only for those 'whose auspicious time had arrived' and that obtaining the 'shell of fortune' from a saint's hand was a destiny reserved for the fortunate, implying a connection to an individual's karma or spiritual readiness.
