How did Sai Baba demonstrate his ability to know people's innermost thoughts, as shown in the story of Laxmichand?

The provided text from Chapter 28 beautifully illustrates Sai Baba's omniscience, or his ability to know the unexpressed thoughts and desires of his devotees. In the case of Laxmichand, Baba demonstrated this power on multiple occasions. First, when Laxmichand silently craved a sweet called 'khaja', Baba, without being told, specifically requested that very sweet be brought as a food offering. Later, when Laxmichand privately wondered if Baba's cough was due to an 'evil eye,' Baba voiced this exact thought aloud the next morning, leaving Laxmichand astonished. These incidents, detailed in Chapter 28, show how Baba could perceive the silent echoes of the heart, reinforcing his devotees' faith that he dwelled within them.
