Describe the incident involving Baba's cough and Laxmichand's thought about the evil eye. What was its significance?

During a Chavadi procession one night, Laxmichand observed Sai Baba coughing and a private thought arose in his mind that the cough might be the result of someone's evil eye. As Chapter 28 recounts, this was a fleeting, internal musing. The profound significance of this event was revealed the very next morning. When Laxmichand came to the masjid, he heard Baba speaking to Madhavrao and saying, "Yesterday I had much coughing; is this the effect of an evil eye?" By perfectly echoing Laxmichand's private thought, Baba demonstrated His omniscience. This left Laxmichand in a state of wonder, solidifying his faith and making him realize that Baba knows everyone's innermost thoughts.
