How did Sai Baba demonstrate his omniscience regarding Laxmichand's craving for khaja?

This story wonderfully illustrates Sai Baba's inner knowledge. As described in Chapter 28, a devotee had brought some khaja as prasad, which Laxmichand enjoyed. For the next day or two, he silently wished for more. On the third day, when devotees went to the masjid to ask Baba what food offering (naivedya) He would like, Baba specifically requested "a plate full of khaja." This was not a coincidence; it was Baba's miraculous way of fulfilling the unexpressed desire in his devotee's heart, proving his profound omniscience and satisfying Laxmichand's attachment.
