Can you tell me the story of how Sai Baba fulfilled Laxmichand's craving for a specific sweet?

Certainly. During a visit to Shirdi, Laxmichand (also referred to as Lalaji) developed a craving for khaja, a sweet he had tasted once as prasad. As described in Chapter 28, this desire lingered in his mind. On the third day, in a display of his omniscience, Sai Baba specifically requested a plate full of khaja as a naivedya offering before the afternoon arati. Later, two bowls of khaja were brought, and Laxmichand, who was very hungry, received the sweet at mealtime. This event fulfilled his unspoken attachment and brought him great joy, solidifying his faith in Baba's inner knowledge.
