How did Sai Baba demonstrate his inner knowledge, or 'antarjnan', to Laxmichand on multiple occasions?

Sai Baba demonstrated his profound inner knowledge to Laxmichand in several remarkable ways, as detailed in Chapter 28. First, when Laxmichand was suffering silently from hunger and back pain, Baba openly spoke words that mirrored his exact condition: 'Hunger has come, that's good. There should be medicine for back pain.' He then mentioned the 'wind of khaja,' directly referencing Laxmichand's unspoken craving. A second instance occurred later, when Laxmichand mentally speculated that Baba's cough might be due to an 'evil eye.' The very next morning, Baba spoke of his cough in similar terms, proving once again that he was aware of Laxmichand's most private thoughts, an event described as an 'echo without sound.'
