Can you explain the miracle of the grapes in Shirdi? I heard a story about someone who disliked seeded grapes but was given them by Baba. What happened?

Chapter 35 details this specific event. A man named Boss Dharamsee, who disliked grapes with seeds, visited Sai Baba. Kaka, another devotee, had brought seeded grapes as an offering because seedless ones were unavailable. When Baba offered them to Dharamsee, he was internally troubled, even thinking that if Baba were a true saint, he would know his dislike. Baba, aware of his thoughts, insisted he eat them. When Dharamsee finally put the grapes in his mouth upon Baba's command, he was amazed to find they were completely seedless. This personal miracle stunned him, dissolved his ego, and ignited a deep love for Sai.
