What was the 'evil eye' incident with Laxmichand and Sai Baba? How did Baba reveal he knew Laxmichand's thoughts?

This incident is a powerful example of Sai Baba's ability to perceive unspoken thoughts. According to Chapter 28, during a Chavadi procession, Baba developed a persistent cough. Laxmichand, observing this, privately thought to himself that the cough might be the result of someone's evil eye. The very next morning, when he went to the masjid, he heard Baba speaking to Madhavrao. Baba said, "Yesterday I had much coughing; is this the effect of an evil eye?" These words perfectly echoed Laxmichand's private mental thought, causing him to wonder how Baba could know what was in his heart and confirming Baba's nature as an indweller of all beings.
