Can you explain how the story of the khaja demonstrates Sai Baba's inner knowledge, or 'antarjnan'?

The incident with Laxmichand and the khaja is a powerful illustration of Sai Baba's 'antarjnan' or inner knowledge. Chapter 28 explains that Laxmichand's desire for the sweet was a private, unexpressed thought. Yet, Baba knew of it and arranged for khaja to be brought the next day. More profoundly, when Laxmichand was suffering from hunger and back pain, Baba's words directly addressed his condition: "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown." This ability to perceive a devotee's silent thoughts and physical ailments, described as an "echo without sound," clearly demonstrates Maharaj's profound inner knowledge.
