Describe the specific moment when Sai Baba revealed his knowledge of Laxmichand's physical discomfort and hunger.

The most striking demonstration of Sai Baba's inner knowledge occurred when Laxmichand was feeling restless from hunger and back pain. As described in chapter 28, just as Laxmichand was suffering, Baba spoke words that directly mirrored his internal 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." The text explicitly notes that these words were a clear expression of what was in Laxmichand's mind, an "echo without sound." This event, as recounted in chapter 28, deeply affected Laxmichand and solidified his faith in Baba's divine perception.
