The text mentions, 'Echo without sound - Maharaj has inner knowledge.' How is this theme of omniscience demonstrated through Laxmichand's various experiences in the provided text?

The theme of Sai Baba's omniscience is demonstrated through multiple interactions with Laxmichand as described in Chapter 28. The first instance is when Laxmichand silently craves khaja, and Baba subsequently asks for that specific sweet to be brought as an offering. Secondly, when Laxmichand was feeling restless due to hunger and back pain, Baba's words directly addressed his condition, saying, "Hunger has come, that's good. There should be medicine for back pain." Finally, the theme is reinforced when Laxmichand privately thinks Baba's cough might be due to an 'evil eye,' and Baba later vocalizes the exact same thought in the morning. Each of these events serves as a powerful example of Baba's 'inner knowledge.'
