Can you elaborate on the incident involving Baba's cough and Laxmichand's thoughts about the evil eye?

Certainly. As recounted in Chapter 28, during one Chavadi procession, Sai Baba developed a cough. Upon witnessing this, his devotee Laxmichand had a private, mental thought that the cough might be the result of someone's evil eye affecting Baba. This was purely a thought that arose in Laxmichand's mind and was not spoken aloud. The very next morning, when Laxmichand went to the masjid, Baba amazed him by speaking words that were similar to Laxmichand's internal speculation from the previous night. This incident served as another powerful demonstration of Baba's antardnyan, or inner knowledge, showing that he was aware of even the most fleeting thoughts of his devotees.
