How did the narrator's feelings about Sathe's quick spiritual progress reveal a deeper lesson about Sai Baba's omniscience?

While massaging Sai Baba's feet, the narrator felt a pang of envy, as detailed in Chapter 18. He internally lamented that Sathe received the fruit of his devotion after only one seven-day reading, while his own efforts over forty years seemed fruitless. This private thought, a comparison of his long wait to a 'Chataka bird' waiting for rain, did not go unnoticed. The text highlights Baba's divine ability to perceive even the most hidden thoughts, stating, 'The thought that arose in my mind at that time, He immediately knew it.' This incident demonstrates that Baba was fully aware of his devotee's inner state, including feelings of jealousy and longing, showcasing his profound love and omniscience.
