What happened when Laxmichand was suffering from hunger and back pain, and what did it reveal about Sai Baba?

While in Shirdi, Laxmichand became restless due to intense hunger and back pain. In that moment of private suffering, Sai Baba spoke words that directly addressed his condition. As recounted in Chapter 28, Baba said, "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown; do the arati quickly." This event was profound because it revealed Baba's omniscience, or inner knowledge. The scripture describes this as an "Echo without sound," signifying that Baba could perceive Laxmichand's silent thoughts and physical ailments, which deeply solidified Laxmichand's faith and devotion.
