Can you describe how Sai Baba demonstrated his omniscience to the devotee Laxmichand regarding a food craving?

The story of Laxmichand beautifully illustrates Sai Baba's inner knowledge. As detailed in Chapter 28, Laxmichand had developed a craving for a sweet called khaja after tasting it as prasad. His desire remained unfulfilled for a day. On the third day, without being asked, Baba instructed a devotee to bring a plate full of khaja as a food offering. Later, as Laxmichand was feeling hungry and had back pain, Baba's words directly addressed his state, saying "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown." This incident, where Baba knew and fulfilled Laxmichand's unspoken desire, is a clear example of His omniscience.
