Can you tell me the story of the two gentlemen from Goa who visited Sai Baba as described in the Satcharitra?

Certainly. Chapter 36 of the Shri Sai Satcharitra narrates an incident involving two gentlemen from Goa who came for Sai Baba's darshan. Upon their arrival, both men surrendered at Baba's feet. A curious event then unfolded where Baba asked for a Dakshina of fifteen rupees from only one of the men, which he gave joyfully. However, when the second man voluntarily offered a larger sum of thirty-five rupees, Baba immediately rejected it. This action surprised everyone present, including Madhavrao (Shama), who questioned Baba about this apparent partiality, setting the stage for a deeper teaching.
