How did Sai Baba demonstrate his inner knowledge, or 'antarjnan', to his devotee Laxmichand?

Sai Baba repeatedly demonstrated his inner knowledge (antarjnan) to Laxmichand, solidifying his faith. Chapter 28 recounts how Laxmichand silently craved khaja after having it once. Without any verbal communication, Baba instructed his followers to bring a plate full of khaja as the day's offering. Furthermore, when Laxmichand was suffering from hunger and back pain, Baba spoke aloud, "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown," perfectly echoing Laxmichand's internal state. Another powerful example is when Laxmichand privately thought Baba's cough was due to an evil eye, and Baba later voiced the exact same thought, proving his ability to perceive the unsaid.
