Can you tell me what happened when the two gentlemen from Goa visited Sai Baba?

Certainly. Chapter 36 recounts the story of two gentlemen from Goa who came for Sai Baba's darshan. Upon their arrival, both surrendered at Sai's feet, filled with joy. A curious event unfolded when Baba asked for a Dakshina of fifteen rupees from only one of them, which the man gave happily. However, when the second gentleman, on his own accord, offered thirty-five rupees, Sai Baba immediately rejected the offering. As described in the chapter, this apparent partiality surprised everyone present, including Madhavrao, also known as Shama, who then questioned Baba about his actions.
