How did Sai Baba's interaction with Mrs. Gokhale demonstrate his omniscience?

The story of Mrs. Gokhale in Chapter 32 serves as a powerful example of Sai Baba's omniscience. Before Mrs. Gokhale even arrived in Shirdi with her secret resolve to fast for three days, Baba already knew her intention. The text states that the 'inner witness Maharaj already knew this from before' and had made a prophetic statement to Dada Kelkar about not letting his 'children remain hungry' during the Shimga festival. The fact that Mrs. Gokhale arrived the very next day, just as Baba had alluded, confirmed his foreknowledge. The narrative explicitly states, 'Whatever is in anyone's heart, Sainath knows everything,' underscoring his divine ability to perceive the thoughts and intentions of all.
