How did Sai Baba demonstrate his knowledge of his devotees' intentions, specifically in relation to food and fasting?

Sai Baba demonstrated his omniscience regarding his devotees' intentions through a specific incident involving food and fasting, as narrated in Chapter 32. A woman named Mrs. Gokhale decided to undertake a three-day fast upon her arrival in Shirdi. Before she even arrived, Baba, the "inner witness Maharaj," was already aware of her private resolve. He made a prophetic statement to Dada Kelkar, questioning how he could possibly let his "children remain hungry" during the Holi festival. True to his words, Mrs. Gokhale arrived the very next day with her plan to fast. The text highlights this as proof that "Sainath knows everything" and that "There is nothing in the whole world that is not known to him." This event serves as a powerful example of how Baba's divine insight was intertwined with his practical teachings on the necessity of food for his devotees' well-being.
