Why did Sai Baba specifically tell Jog to give Cholkar tea with lots of sugar? What was the significance?

Sai Baba's specific instruction to Jog to serve Cholkar 'cups of tea, well-filled with sugar' was highly significant and not a casual remark. According to Chapter 15, Baba himself did not drink tea, so his sudden mention of it was purposeful. The primary goal was to provide a powerful confirmation of Cholkar's faith and to impress the 'stamp of devotion' on his heart. Cholkar had secretly vowed to abstain from sugar until he could visit Shirdi. By explicitly mentioning sugar upon the vow's completion, Baba proved His omniscience, showing that He was aware of Cholkar's private penance, the long delay in fulfilling the vow, and the state of his mind all along. It was a direct, personal sign that Cholkar's devotion and sacrifice had been seen and accepted by Baba.
