Can you explain the miracle with the sugary tea that happened to Cholkar in Shirdi?

The miracle of the sugary tea demonstrated Sai Baba's omniscience. As Chapter 15 recounts, after Cholkar was delayed in fulfilling his vow to distribute sugar, he secretly gave up sugar himself as a personal penance. When he finally arrived in Shirdi and fulfilled the vow, he was a guest at Jog's place. As he was leaving, Baba specifically told Jog, "Give him cups of tea, well-filled with sugar." This instruction was miraculous because Baba did not drink tea, and more importantly, He knew about Cholkar's secret renunciation of sugar. This act served as a powerful confirmation for Cholkar that Baba knew his innermost thoughts, his vow, the delay, and his private penance.
