Based on the text, did Sai Baba give money to every single beggar and fakir who came to his door?

No, the text explicitly clarifies that Sai Baba did not give money to every person who asked. While Chapter 29 describes him as merciful and his door as always having fakirs and beggars, it states, 'Though Baba was merciful, he did not give to all alike.' The chapter further explains, 'he did not give to everyone - no one knew his mind.' Receiving a monetary blessing from Sai Baba was considered a matter of fortune, granted only when a person's 'auspicious time had arrived.' This shows that his generosity, while immense, was also selective and inscrutable.
