Who was the devotee that had a strong craving for khaja, and how did Baba know about it?

The devotee who craved khaja was Laxmichand. According to Chapter 28, after having the sweet once during his visit to Shirdi, he developed a strong desire for it again, but this eagerness remained only in his mind. Demonstrating his omniscience, Sai Baba specifically ordered a devotee to bring a plate full of khaja as a food offering (naivedya). Baba then told his devotees he felt like having khaja and that it should be served to everyone. The text calls this an example of Baba's "inconceivable knowledge," as he fulfilled Laxmichand's unspoken wish without being told.
