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

Sai Baba demonstrated His omniscience, or His ability to know the innermost thoughts of His devotees, on multiple occasions with Laxmichand. As detailed in Chapter 28, Laxmichand had a private craving for khaja (a sweet), and Baba orchestrated events by specifically requesting khaja as a food offering, thereby fulfilling the unexpressed desire. In an even more profound instance, Laxmichand privately wondered if Baba's cough was due to an 'evil eye.' The very next morning, Baba repeated this exact sentiment, asking if an 'evil eye' was the cause of His cough. This caused Laxmichand to realize that Baba dwells in everyone's heart, proving His divine inner knowledge.
