How did the incident with the khaja and Baba's knowledge of his pain affect Laxmichand's devotion?

The incident had a profound and transformative effect on Laxmichand's devotion. According to Chapter 28, Laxmichand was feeling restless from hunger and back pain when he heard Sai Baba speak words that perfectly described his condition, saying there should be "medicine for back pain" and that the "wind of khaja has blown." Laxmichand was astonished that Baba could know his innermost thoughts and physical suffering, an event the text calls an "Echo without sound." This direct experience of Baba's inner knowledge (antarjnana) caused his love for Baba to become firmly fixed. From that moment on, as Chapter 28 details, he established a regular practice of worship and would consistently send offerings like garlands, camphor, and incense to Baba in Shirdi.
