What was Laxmichand's private thought about Baba's cough, and how did it demonstrate Baba's omniscience?

As recounted in Chapter 28, after Laxmichand's devotion had become firmly established, he was present for a Chavadi procession where Baba developed a cough. In his mind, Laxmichand privately thought, 'Why does this cough trouble him? It seems like someone's evil eye has affected him.' This was just a mental thought. However, demonstrating his inner knowledge, when Laxmichand came to the masjid the next morning, Baba spoke words that were similar to the devotee's own unspoken thought, proving that nothing, not even a private mental speculation, was hidden from him.
