I heard Baba once coughed and knew someone thought it was an 'evil eye'. Can you give me the details of that story with Laxmichand?

Yes, that event involving Laxmichand is detailed in Chapter 28 of the Sai Satcharitra. During one of the Chavadi processions at night, Sai Baba developed a persistent cough. Seeing this, Laxmichand had a private thought, wondering if the cough was troubling Baba because someone's 'evil eye' had affected him. It was just a fleeting mental notion that he kept to himself. However, the next morning when Laxmichand went to the masjid, Baba himself brought up the topic and spoke in a similar manner, alluding to the idea of an evil eye. This incident was another profound demonstration of Baba's 'inner knowledge,' confirming his ability to perceive the unexpressed thoughts of his devotees.
