Can you tell me the story about Sai Baba and the grapes? I heard he changed them for a devotee.

Yes, this story involves a man named Boss Dharamsee who was visiting Shirdi out of curiosity about miracles. When grapes were offered to Sai Baba, Baba began distributing them. Dharamsee received some but was disappointed as he disliked grapes with seeds and his doctor had forbidden him from eating unwashed fruit. As he internally questioned Baba's sainthood for giving him something he disliked, Baba gave him even more. Finally, Baba commanded him to eat the grapes he was holding. As detailed in Chapter 35, when Dharamsee put them in his mouth, he was astonished to find they were all seedless. This experience transformed his skepticism into deep love and reverence for Sai.
