How did Sai Baba's interaction with Laxmichand regarding food demonstrate his divine insight?

Sai Baba's interaction with Laxmichand beautifully illustrates his omniscience. As recounted in Chapter 28, Laxmichand was suffering from intense hunger and a backache. At this very time, Baba, without being told, vocalized the devotee's condition by saying, "Hunger has come, that's good. There should be medicine for back pain." He then mentioned that the "wind of khaja has blown," directly referencing the food he had earlier asked Laxmichand to bring. This event, described as an "echo without sound," showed that Baba was intimately aware of his devotee's physical suffering and inner desires, using the offering of food as a means to reveal his divine knowledge.
