What is the story of Laxmichand's hunger and back pain in Shirdi?

According to Chapter 28 of the Shri Sai Satcharitra, a devotee named Laxmichand was in Shirdi and feeling very restless due to hunger and back pain. In that moment, Sai Baba, demonstrating his inner knowledge, spoke out loud saying, "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown; do the arati quickly." These words perfectly mirrored Laxmichand's unspoken thoughts and physical discomfort. The text highlights this as an "echo without sound," showing Maharaj's omniscience. After the arati was completed, khaja was served, fulfilling Laxmichand's craving and bringing him great joy.
