How did Sai Baba demonstrate his ability to know a devotee's inner desires, specifically regarding food?

Sai Baba demonstrated his inconceivable knowledge through his interactions with the devotee Laxmichand. As described in Chapter 28, Laxmichand had a desire for khaja, a sweet he had tasted on his first day in Shirdi. This eagerness remained in his mind. The very next day, a wonder occurred. Baba instructed a devotee who asked what naivedya to bring to prepare "a plate full of khaja." Later, after the arati, Baba announced to all, "Today is an auspicious day; I feel like having khaja prasad." Subsequently, bowls of khaja were brought and served, directly fulfilling Laxmichand's unspoken craving and demonstrating that Baba was aware of his innermost thoughts.
