Can you explain the significance of the khaja prasad in the story of Laxmichand?

The khaja prasad is central to a story in Chapter 28 that illustrates Sai Baba's omniscience and his method of fulfilling devotees' desires. After having a small amount of khaja prasad on his first day, a devotee named Laxmichand developed a lingering craving for it. Then, in a wonderful display of his divine play, Baba himself ordered that khaja be brought as a naivedya offering before the arati. He then announced his own desire to have khaja and ensured it was distributed to everyone, thus satisfying Laxmichand's unspoken wish. This specific prasad became the "medicine" for Laxmichand's restlessness and the catalyst for his deep-seated love and devotion to Baba.
