How did Sai Baba demonstrate his inner knowledge to the devotee Laxmichand?

Sai Baba demonstrated his inconceivable inner knowledge in a remarkable way with the devotee Laxmichand. As detailed in Chapter 28, Laxmichand was feeling restless due to hunger and back pain, and he was also intensely craving a sweet called khaja. Baba, being omniscient, perfectly verbalized Laxmichand's internal state without being told. The text notes, "Whatever was in Laxmichand's mind, that was clearly expressed in Baba's words." Baba specifically mentioned the hunger, the need for medicine for back pain, and the craving for khaja, telling everyone to "do the arati quickly." This event, described as an "echo without sound," showed that Maharaj possessed profound inner knowledge, fulfilling Laxmichand's desire and solidifying his devotion.
