How did Sai Baba demonstrate his inner knowledge, or antarjnan, to Laxmichand?

Sai Baba demonstrated his inner knowledge to Laxmichand on multiple occasions, as detailed in Chapter 28. First, when Laxmichand was silently craving a sweet called khaja, Baba, without being told, specifically ordered that exact sweet for the naivedya. Later, when Laxmichand suffered from hunger and back pain, Baba's words directly referenced his condition: "Hunger has come, that's good. There should be medicine for back pain." In another instance, Laxmichand privately thought Baba's cough might be from an evil eye. The very next morning, Baba voiced this exact thought, proving to Laxmichand that he dwells in everyone's heart.
