The text mentions Baba's 'inner knowledge.' What specific details from Laxmichand's experience prove this attribute of Sai Baba?

Chapter 28 of the Shri Sai Satcharitra provides multiple, powerful examples of Sai Baba's 'inner knowledge,' or antargyan. When Laxmichand arrived, Baba instantly knew details of his journey, asking why he was doing bhajan on the road and why he had to borrow money. This left Laxmichand wondering, 'how did Baba know that here?' Furthermore, Baba was aware of Laxmichand's unexpressed desire for khaja, which he fulfilled by specifically asking for it as an offering. Most strikingly, Baba perceived Laxmichand's physical and mental state, voicing his exact discomfort by saying, 'Hunger has come, that's good. There should be medicine for back pain.' These instances are described as an 'echo without sound,' proving Baba's inconceivable knowledge.
