Can you summarize the beginning of Chapter 36 of the Shri Sai Satcharitra, including the story of the two men from Goa?

Certainly. Chapter 36 begins with an invocation and a powerful description of listening to Sai's stories, calling them the "water of self-bliss" that removes worldly misery and increases one's thirst for devotion. The text then praises Sai's infinite and indescribable greatness, portraying him as a playful being who reveals his own qualities through others and can create inconceivable events. This introduction leads into a story about two gentlemen from Goa who visit Sai for his darshan. As narrated in Chapter 36, Sai puzzlingly asks for and accepts a 15 rupee offering from one man but outright rejects a 35 rupee offering from the other, which confused everyone present.
