I'm skeptical about the miracles attributed to Sai Baba. What does the Satcharitra say about how he dealt with doubters like Boss Dharamsee?

The Satcharitra provides a detailed account of just such an instance in Chapter 35. When Boss Dharamsee arrived, he was driven by curiosity and had a 'clinical scrutiny.' He disliked the seeded grapes Baba offered and thought, 'If he is a saint, how does he not know That I do not like these grapes?' Rather than rebuke him, Baba engaged with his doubt directly. He gave Dharamsee more grapes and commanded him to eat. When Dharamsee obeyed, he found the grapes had miraculously become seedless. This personal experience completely transformed his perspective, causing his ego to drop away and be replaced by love for Sai. This demonstrates that Baba often addressed skepticism not with words, but with direct, personal experiences that revealed a higher reality.
