Can you detail an instance where Sai Baba knew about a devotee's private thoughts concerning Baba's own health?

Chapter 28 recounts a time when Sai Baba developed a cough during the Chavadi procession. A devotee named Laxmichand, upon seeing this, privately thought to himself that the cough might be the result of someone's 'evil eye'. The very next morning in the masjid, Baba amazed Laxmichand by speaking this exact thought aloud. He said to Madhavrao, 'Yesterday I had much coughing; is this the effect of an evil eye?' This event caused Laxmichand to wonder how Baba could know his personal thoughts, leading him to conclude that Baba truly dwells in everyone's heart.
