Describe the incident involving Laxmichand's craving for a specific sweet and how Sai Baba responded to this unspoken desire.

The Sai Satcharitra recounts a time when a devotee named Laxmichand was visiting Shirdi. After having a sweet called khaja on the first day, he developed a craving for it again. As detailed in Chapter 28, this desire remained unfulfilled on the second day. On the third day, a wonder occurred. When devotees asked Baba what naivedya (food offering) they should bring, He specifically requested a plate full of khaja. Later, He instructed everyone to serve the khaja, satisfying Laxmichand's hidden hunger and fulfilling his lingering desire, demonstrating Baba's inconceivable knowledge of his devotees' minds.
