How did Sai Baba reveal to Cholkar that He was aware of his secret renunciation of sugar?

The climax of Cholkar's story in Chapter 15 reveals Baba's profound awareness. After Cholkar had fulfilled his vow by distributing sugar, he went to visit with a devotee named Jog. As Cholkar was about to leave, Sai Baba, who did not drink tea Himself, gave a specific instruction to Jog: "Give him cups of tea, well-filled with sugar." Hearing these meaningful words, Cholkar was amazed and moved to tears, as it was a direct and undeniable confirmation that Baba knew the secret of his vow and his personal penance of renouncing sugar during the long delay. This experience served to deeply impress the stamp of devotion and confirm Cholkar's faith.
