How does Cholkar's experience demonstrate Sai Baba's omniscience and connection to his devotees?

Cholkar's experience is a powerful illustration of Sai Baba's omniscience. According to Chapter 15, Baba knew every secret detail of Cholkar's situation without being told. He knew about the original vow made to pass an exam, the financial hardship ('threshold-ghat') that caused a delay, and, most impressively, the private penance Cholkar undertook by giving up sugar. By instructing Jog to serve Cholkar tea 'well-filled with sugar,' Baba proved that he was aware of Cholkar's innermost thoughts and actions. Baba then articulated this principle, stating, 'Even if my body is here, and you are beyond the seven seas, Whatever you do there, I know it instantly,' confirming his constant presence in the hearts of his devotees.
