How did Sai Baba demonstrate his omniscience to the devotee Laxmichand upon his arrival in Shirdi?

Chapter 28 of the Shri Sai Satcharitra details how Baba demonstrated his omniscience to Laxmichand in several profound ways. Upon Laxmichand's arrival, Baba immediately questioned him about doing bhajan on the road and borrowing from a moneylender for the trip, which amazed the devotee. Baba directly asked, 'Borrowing from Marwadi (moneylender), what was the need for darshan?' Later, Baba also verbally expressed Laxmichand's exact physical state, mentioning his hunger and back pain, saying, 'Hunger has come, that's good. There should be medicine for back pain.' This proved that Baba had complete inner knowledge of Laxmichand's thoughts, actions, and physical sensations.
