How was Baba's omniscience demonstrated in the context of his teachings about food and fasting?

Sai Baba's omniscience was clearly demonstrated through the incident with Mrs. Gokhale, as detailed in Chapter 32. Before the woman even arrived in Shirdi with her secret intention to fast for three days, Baba, the "inner witness Maharaj," already knew her plan. He had made a prescient remark to Dada Kelkar during the Shimga festival, asking, "will my children remain hungry? How can I let them remain so? Then what am I needed for?" The very next day, Mrs. Gokhale arrived. This event powerfully illustrates the teaching that Sainath knows everything in a devotee's heart and that nothing in the world is hidden from him, reinforcing his divine knowledge and his specific disapproval of fasting.
