Why did Sai Baba accept Dakshina from one man from Goa but reject it from the other?

The provided text in Chapter 36 of the Shri Sai Satcharitra describes the incident but does not immediately provide the reason for Sai Baba's actions. It narrates that two gentlemen from Goa came for darshan, and Baba accepted fifteen rupees from one while pointedly refusing thirty-five rupees from the other. This act of apparent partiality caused great surprise among the onlookers. The chapter highlights this as a mysterious event, noting that Madhavrao (Shama) was also perplexed and asked Sai for an explanation. The text sets this up as an inconceivable event that demonstrates Baba's prowess, with the implication that the reason will be revealed later.
