How does Sai Baba deal with people who are skeptical or approach him with a 'clinical' interest?

Sai Baba has his own unique ways of handling skepticism and transforming it into faith. As described in Chapter 35, a man named Boss Dharamsee came to Shirdi with a 'clinical scrutiny' and an ego-driven attitude. He mentally questioned Baba's sainthood when offered grapes he disliked. Baba, knowing his innermost thoughts, performed a subtle miracle. The grapes with seeds that Baba gave him miraculously became seedless in his mouth, while they remained seeded for another devotee. This direct, personal experience shattered Dharamsee's ego, causing his skepticism to vanish and be replaced by love and a firm determination to return to Shirdi.
