What were the specific circumstances that led to Baba asking for khaja as a food offering?

The specific circumstances were driven by the unspoken desire of a devotee, Laxmichand. As narrated in Chapter 28, Laxmichand had a small amount of khaja prasad and was left with a lingering desire for more. This thought remained with him. Two days later, when devotees approached Baba in the masjid to ask what naivedya he would like for the day, Baba, being aware of Laxmichand's inner wish, specifically commanded, "Bring me a plate full of khaja; then do the arati-puja." This divine instruction was not random; it was a direct response to a devotee's silent prayer, setting the stage to fulfill that desire and reinforce the devotee's faith in his omniscience.
