How does the story of Mrs. Gokhale's planned fast demonstrate Sai Baba's omniscience?

The story of Mrs. Gokhale serves as a clear example of Sai Baba's omniscience. As Chapter 32 narrates, Baba was aware of her secret intention to fast for three days before she even reached Shirdi. The text explicitly states, 'The inner witness Maharaj already knew this from before.' He demonstrated this foreknowledge by making a predictive statement to Dada Kelkar about not allowing his 'children' to go hungry during the Holi festival, right before Mrs. Gokhale's arrival. When she finally came for darshan, Baba acted on this hidden knowledge. This incident is presented as proof that 'Sainath knows everything' and that 'There is nothing in the whole world that is not known to him,' confirming his ability to perceive the innermost thoughts of his devotees.
