The Satcharitra mentions Baba had 'inner knowledge.' How was this demonstrated in his interactions with Laxmichand?

Sai Baba's profound inner knowledge, or omniscience, is clearly demonstrated through his interactions with Laxmichand in Chapter 28. When Laxmichand was feeling both hungry and suffering from back pain, Baba's words directly reflected his condition: 'Hunger has come, that's good. There should be medicine for back pain.' The text notes this was an 'Echo without sound,' as Baba articulated what was only in Laxmichand's mind. Similarly, Baba knew of Laxmichand's unspoken craving for khaja and orchestrated events to fulfill it. These incidents showed that Baba could perceive the most subtle physical and mental states of his devotees without any external communication.
