How did Sai Baba demonstrate his omniscience or 'inner knowledge' to the devotee Laxmichand?

Sai Baba demonstrated his inner knowledge to Laxmichand in multiple ways, as detailed in Chapter 28. First, when Laxmichand silently craved a sweet called khaja after having it once, Baba specifically requested that very sweet as a food offering the next day, fulfilling the devotee's unexpressed desire. Later, when Laxmichand was suffering from hunger and back pain, Baba's words directly addressed his discomfort, stating, "Hunger has come, that's good. There should be medicine for back pain." This event, described in Chapter 28, shows how Baba could perceive the physical and mental state of his devotees without being told.
