What are the key instances in the story of Laxmichand that showcase Sai Baba's omniscience?

Chapter 28 provides two distinct instances showcasing Sai Baba's omniscience, or 'antarjnan', through his interactions with Laxmichand. The first is when Baba explicitly mentioned Laxmichand's unspoken afflictions of hunger and back pain just before the khaja prasad was served, stating "Hunger has come, that's good. There should be medicine for back pain." The second key instance occurred later, after Laxmichand privately worried that Baba's cough during the Chavadi procession was due to an "evil eye." The very next morning, Baba brought up the subject himself, proving once again that he had direct knowledge of his devotee's silent thoughts.
