Can you describe how Sai Baba demonstrated his omniscience to Laxmichand?

Sai Baba demonstrated his omniscience to Laxmichand on multiple occasions, proving He knew Laxmichand's innermost thoughts. The first instance, described in Chapter 28, was when Laxmichand was silently craving a sweet called khaja. Baba, without being told, ordered that very sweet and also mentioned Laxmichand's hunger and back pain. In another incident, Laxmichand privately wondered if a cough Baba developed was due to an 'evil eye.' The very next morning, Baba voiced this exact thought, asking Madhavrao if his cough could be from an evil eye. These events convinced Laxmichand that Baba dwells in everyone's heart.
