Describe the moment Sai Baba used the phrase 'wind of khaja' and what it signified for Laxmichand.

This event occurred on the third day of Laxmichand's visit when he was feeling both hungry and a pain in his back. As Chapter 28 recounts, after Baba had already requested khaja, He looked at Laxmichand and spoke words that directly addressed his physical and mental state. Baba said, "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown; do the arati quickly." This phrase signified that his unspoken desire was about to be fulfilled, confirming for Laxmichand that Baba possessed profound inner knowledge and was orchestrating events to satisfy his devotee's longing.
