How does Sai Baba's interaction with Dharamsee demonstrate his omniscience and his ability to tailor experiences for individual devotees?

The encounter between Sai Baba and Boss Dharamsee in Chapter 35 is a masterclass in Baba's omniscience and personalized spiritual guidance. Baba was acutely aware of every detail of Dharamsee's inner state: his dislike for grapes with seeds, his doctor's advice, and his silent, skeptical thought, "If he is a saint, how does he not know That I do not like these grapes?" In response to this internal challenge, Baba performed a miracle precisely tailored to Dharamsee's doubt. The grapes, which had seeds for another devotee named Tarkhad, became seedless only for Dharamsee. This proved to Dharamsee that Baba knew the "intent of my mind" and that whatever he gives is "beneficial." This highly personal experience was designed to dismantle his specific ego structure, which is how love for the saint was born in his heart.
