How did Sai Baba use a simple cup of tea to reinforce Cholkar's faith?

The incident with the cup of tea was a pivotal moment for Cholkar's faith. As described in Chapter 15, Cholkar had made a vow involving sugar candy and had also secretly given up sugar as a penance for delaying his visit. After he finally arrived in Shirdi and fulfilled the vow, he was a guest of Jog. As he was about to leave, Sai Baba, who notably did not drink tea Himself, specifically instructed Jog: "Give him cups of tea, well-filled with sugar." This seemingly simple request was a direct and powerful confirmation for Cholkar. It showed that Baba knew the secret details of his vow and his personal sacrifice, causing tears of joy to stream from Cholkar's eyes and immovably confirming his faith and devotion.
