Can you explain the significance of Baba asking Jog to give Cholkar tea with extra sugar?

The incident with the tea is a pivotal moment in Cholkar's story, demonstrating Baba's omniscience. As narrated in Chapter 15, after Cholkar had fulfilled his vow and was a guest of Jog, Sai Baba specifically instructed Jog to serve Cholkar "cups of tea, well-filled with sugar." This was highly unusual as Baba himself did not drink tea. Cholkar was immediately overwhelmed with emotion because this was a direct and clear sign that Baba knew about his secret vow to abstain from sugar and the personal sacrifice he had made. The act served to deeply confirm Cholkar's faith, proving that Baba was aware of his devotee's innermost thoughts and penance, even those kept secret.
