Can you tell me the story of how Sai Baba turned grapes with seeds into seedless ones?

This is a wonderful story of how Baba addressed a devotee's skepticism. As recounted in Chapter 35, a man named Boss Dharamsee was visiting Shirdi with a critical mindset. He disliked grapes with seeds, and when offered some by Baba, he mentally questioned Baba's sainthood. In response to this unspoken challenge, Baba commanded him to eat the grapes. When Dharamsee obeyed, he was astonished to find that the grapes in his mouth were completely seedless, a miracle that instantly dissolved his ego and established his faith in the saint's power.
