How did Sai Baba leverage the presence of Jog to create a powerful experience for Cholkar?

As Chapter 15 recounts, Cholkar was a guest of the devotee Jog. Sai Baba skillfully used this situation to create a profound moment of realization for Cholkar. As Cholkar and Jog were together, Baba instructed Jog to give Cholkar "cups of tea, well-filled with sugar." For Jog, this was a simple act of hospitality, but for Cholkar, it was a miracle. Baba, who did not drink tea, used Jog as an intermediary to deliver a message that only Cholkar could understand, confirming that his secret vow and personal penance of avoiding sugar were known to the Master. This confirmed Cholkar's faith and showed Baba's skill in providing personal experience to his devotees.
