I heard a story where Sai Baba's cough was thought to be from an 'evil eye'. Can you explain what happened?

This incident, detailed in Chapter 28, showcases Sai Baba's omniscience. During a Chavadi procession one night, Baba developed a cough. A devotee named Laxmichand, who was present, had a private thought, wondering if the persistent cough was the result of someone's 'evil eye' affecting Baba. The narrative states this was just a mental thought that arose in his mind. The next morning, when Laxmichand came to the masjid, he was stunned to hear Baba say to Madhavrao, 'Yesterday I had much coughing; is this the effect of an evil eye?' By perfectly echoing Laxmichand's secret thought, Baba revealed his divine nature, leaving the devotee amazed at how Baba could know what was in his heart.
