Can you tell me about the two gentlemen from Goa who came to see Sai Baba in Chapter 36?

Certainly. Chapter 36 of the Shri Sai Satcharitra recounts the story of two gentlemen from Goa who came for Sai Baba's darshan. Upon their arrival, both men surrendered at Sai's feet. In a curious turn of events, Baba asked for Dakshina of fifteen rupees from only one of them, which the man gave joyfully. When the second gentleman offered thirty-five rupees of his own accord, Sai Baba immediately rejected the offering. This apparent partiality surprised everyone present, including Madhavrao, also known as Shama, who then asked Baba to explain his actions.
