How did Sai Baba demonstrate His omniscience, or inner knowledge, to his devotee Laxmichand?

Sai Baba demonstrated His omniscience to Laxmichand on multiple occasions, revealing that He knew the devotee's innermost thoughts and feelings. As detailed in Chapter 28, one instance involved Laxmichand's unspoken craving for khaja, a sweet he had tasted the previous day. Without being told, Baba specifically ordered a plate full of khaja and expressed a desire to have it as prasad, thus fulfilling Laxmichand's wish. In another incident, Laxmichand privately worried that a cough Baba developed was due to an 'evil eye.' The very next morning, Baba openly wondered aloud if His cough was the effect of an evil eye, perfectly echoing Laxmichand's secret thought. These events convinced Laxmichand of Baba's ability to dwell in everyone's heart.
