Describe the series of events that led to Laxmichand's devotion to Sai Baba becoming firmly established.

Laxmichand's devotion was solidified through a series of experiences that revealed Sai Baba's divine insight. According to Chapter 28, it began when Laxmichand developed a strong desire for khaja, a sweet he had tasted. Baba, aware of this unspoken craving, miraculously arranged for khaja to be offered and served. He even commented on Laxmichand's hunger and back pain, showing he knew his physical state. Later, when Baba developed a cough, Laxmichand privately thought it was due to an "evil eye." The next day, Baba repeated this exact thought aloud. These events, where Baba proved he knew Laxmichand's mind and heart, convinced him of Baba's divinity, and his devotion became a regular practice of sending offerings.
