Can you recount the incident involving the two gentlemen from Goa as narrated in Chapter 36?

Certainly. Chapter 36 narrates an incident where two gentlemen from Goa came for Sai Baba's darshan. Both men surrendered at his feet, but Sai interacted with them differently regarding Dakshina. He specifically requested and accepted fifteen rupees from one of the men. However, when the second gentleman tried to offer thirty-five rupees of his own accord, Sai Baba immediately rejected the offering. This act of apparent partiality was perplexing, causing great surprise among everyone present, including Madhavrao (Shama), who then questioned Sai about it.
