Regarding the visitors from Goa, can you detail the specific amounts of Dakshina involved and Sai Baba's reaction to each offering?

Certainly. Chapter 36 details the peculiar interaction regarding Dakshina with the two gentlemen from Goa. Sai Baba specifically requested a Dakshina of fifteen rupees from only one of the men. That devotee gave the amount joyfully. In stark contrast, the second gentleman was not asked for any money at all. When this second man, on his own initiative, tried to offer thirty-five rupees, Sai Baba immediately rejected his offering. As mentioned in the chapter, this seemingly unequal treatment surprised everyone and prompted Shama to question Sai about the reason for his actions.
