How does the anecdote about the two gentlemen from Goa illustrate the principles of Sai Baba's operation mentioned earlier in the chapter?

The incident involving the two gentlemen from Goa, as narrated in Chapter 36, serves as a practical demonstration of Sai Baba's mysterious nature. The chapter begins by stating that Sai creates many inconceivable events and shows various forms to those he graces. The story then presents a puzzling scenario: Baba accepts a specific requested offering of fifteen rupees from one man but rejects a larger, unsolicited offering of thirty-five rupees from his companion. This action, which seemed like partiality, perfectly illustrates the earlier point that Sai's ways are beyond conventional understanding and that he causes events to occur for reasons known only to him.
