Can you detail the experience of Laxmichand that demonstrated Baba's omniscience?

Certainly. Chapter 28 recounts a profound incident with a devotee named Laxmichand. While observing Baba, Laxmichand privately thought that Baba's persistent cough might be the result of an 'evil eye.' To his complete astonishment, when he approached the masjid, Baba Himself voiced this exact sentiment, saying, 'It seems someone's evil eye has struck me; Therefore this cough again and again causes distress to my life.' This moment, as described in Chapter 28, was a revelation for Laxmichand, making him realize that Baba dwells within everyone's heart and is aware of their innermost thoughts. He immediately pleaded for Baba's continued grace and protection.
