How did Sai Baba's specific instruction about the tea serve as the ultimate confirmation of faith for Cholkar?

The ultimate confirmation of Cholkar's faith came in a moment of divine omniscience. As recounted in Chapter 15, after Cholkar had fulfilled his formal vow, he was visiting with his host, S.B. Jog. As they were about to part, Sai Baba, who did not drink tea Himself, gave a very specific instruction to Jog: 'Give him cups of tea, well-filled with sugar.' This was deeply meaningful because Cholkar had secretly given up sugar as a personal penance during the long delay in fulfilling his vow. Upon hearing these words, Cholkar 'was amazed in his mind,' and tears of joy came to his eyes. It was a clear sign that his secret vow, the delay, and his private sacrifice were all intimately known to Baba, which stamped his heart with unwavering devotion.
