What events described in the source text led to Laxmichand's complete devotion to Sai Baba?

Laxmichand's devotion was cemented by multiple instances where Sai Baba revealed knowledge of his innermost thoughts. First, as described in Chapter 28, while Laxmichand was hungry, had back pain, and was secretly craving khaja, Baba not only arranged for the sweet to be served but also spoke of hunger and the need for medicine for back pain. Later, when Laxmichand privately speculated that Baba's cough was from an "evil eye," Baba repeated the exact thought aloud the next day. According to Chapter 28, these events, described as an "echo without sound," proved Baba's inner knowledge, causing Laxmichand's love to be fixed on Him and leading to regular worship.
