According to Chapter 14, what Dakshina did Gajanan Maharaj request from Ratanji, and what was its significance?

This question contains a factual error based on the provided text. It was Sai Baba, not Gajanan Maharaj, who requested Dakshina from the Parsi merchant Ratanji. As detailed in Chapter 14, after Ratanji made his offerings, 'Baba said to him: "You have come today; what Dakshina (offering) will you give Me? Then you will be fulfilled."' The text further elaborates that asking for Dakshina was a characteristic practice of Sai Baba with all his devotees, regardless of their religion. The provided excerpts do not mention Gajanan Maharaj at all; the interaction is solely between Ratanji and Sai Baba.
