How did Sai Baba know about Laxmichand's craving for khaja and what happened next?

According to the narrative in Chapter 28, Laxmichand developed a desire for more khaja (a sweet) after having a little of it as prasad. This eagerness remained in his mind. In a display of his omniscience, Sai Baba orchestrated the fulfillment of this unspoken desire. On the third day, when devotees asked what naivedya (food offering) they should bring, Baba specifically requested a plate full of khaja. Later, after the arati, he declared, "Today is an auspicious day; I feel like having khaja prasad." Devotees then brought two bowls of the sweet, and Laxmichand's attachment was fulfilled, filling his heart with joy and deepening his faith.
