Can you explain the different ways Sai Baba demonstrated his "inner knowledge" or omniscience in the story of Laxmichand?

The story of Laxmichand in Chapter 28 provides multiple clear examples of Sai Baba's omniscience. First, when Laxmichand silently craved khaja, Baba, knowing this unexpressed desire, specifically instructed devotees to bring him "a plate full of khaja." Second, while Laxmichand was suffering from hunger and back pain, Baba's words directly addressed his condition: "Hunger has come, that's good. There should be medicine for back pain." The text calls this an "echo without sound." Finally, after becoming a devotee, Laxmichand mentally speculated that Baba's cough might be due to an evil eye. The very next morning, Baba verbalized this exact thought, proving again that he possessed inconceivable inner knowledge.
