How did Sai Baba demonstrate that he was aware of Laxmichand's unspoken desire for khaja?

Chapter 28 illustrates Sai Baba's omniscience through the story of Laxmichand and the khaja. After enjoying some khaja prasad one day, Laxmichand secretly wished for more, but the eagerness remained unfulfilled in his mind. On the third day, in a display of his inner knowledge, Baba instructed devotees who asked what naivedya to bring to, "Bring me a plate full of khaja." Later, as Laxmichand was feeling particularly hungry, Baba announced to all, "Today is an auspicious day; I feel like having khaja prasad." This sequence, as detailed in Chapter 28, directly fulfilled Laxmichand's private craving, proving that Baba knew the innermost thoughts of his devotees.
