Why did Sai Baba specifically ask for tea with a lot of sugar for Cholkar? What is the significance of this event?

The significance of Sai Baba asking for tea "well-filled with sugar" for Cholkar is profound and central to his story in Chapter 15. After making a vow to distribute sugar candy upon passing an exam, Cholkar had given up consuming sugar himself until he could fulfill his promise in Shirdi. This was a secret penance known only to him. When Baba specifically mentioned giving him sugary tea, it was a clear and undeniable sign that Baba was all-knowing. As the text states, this was done so that "Cholkar’s faith would be confirmed and the stamp of devotion would be impressed." It wasn't that Baba drank tea, but that He used this specific moment to show Cholkar that his secret vow, the delay, and his personal sacrifice were all known to Him.
