What was the story behind Laxmichand's craving for khaja and how was it fulfilled?

The story from Chapter 28 recounts how Laxmichand's desire for a sweet called khaja was fulfilled by Sai Baba's grace. While on a pilgrimage, Laxmichand enjoyed some khaja on the first day. On the second day, he craved it again, but none was available, and the eagerness remained in his mind. The very next day, a devotee asked Baba what food offering, or naivedya, to bring. Maharaj specifically instructed, "Bring me a plate full of khaja." Later, after the afternoon arati, Baba announced his desire to eat khaja prasad and instructed that it be served to everyone. Two bowls full were brought, and Laxmichand, who was very hungry, received the sweet, satisfying his desire and filling his heart with joy.
