How did Sai Baba know that Laxmichand was craving khaja and how was that desire fulfilled?

According to the narrative in Chapter 28, Laxmichand developed a craving for khaja after having a little of it as prasad. The next day, his desire remained unfulfilled. On the third day, during worship, Sai Baba specifically ordered his devotees to bring a plate full of khaja for naivedya before the arati. Later, he told everyone he felt like having khaja prasad and it was subsequently served, fulfilling Laxmichand's unspoken wish. This demonstrates Baba's inconceivable knowledge and his unique way of satisfying the desires of his devotees.
