How did Sai Baba demonstrate his ability to know people's innermost thoughts to his devotee Laxmichand?

Sai Baba demonstrated his omniscience to Laxmichand on multiple occasions, as recounted in Chapter 28 of the Shri Sai Satcharitra. One instance was when Laxmichand was silently craving a sweet called khaja. Without being told, Baba specifically asked for khaja to be brought as an offering, fulfilling the devotee's secret wish. Another profound example occurred when Laxmichand privately thought that Baba's cough during the Chavadi procession might be due to an "evil eye." The very next morning, Baba repeated this exact thought aloud, wondering if an evil eye had caused his cough. This event made Laxmichand realize that Baba dwells in everyone's heart and knows their every thought.
