How did Sai Baba handle individuals who were skeptical or doubtful of his abilities?

The story of Boss Dharamsee in Chapter 35 provides a clear example of Sai Baba's methods for dealing with skepticism. Dharamsee arrived with a 'clinical scrutiny' and began to doubt Baba's sainthood when offered grapes with seeds, a variety he disliked. Instead of offering a verbal explanation, Baba intensified the situation by giving him even more grapes. As Chapter 35 recounts, when Dharamsee was commanded to eat them, he found they had miraculously become seedless. This direct, personal experience completely dismantled his ego and doubt, replacing it with 'love for the saint.' Baba's approach was to provide an undeniable experience that transformed the heart, rather than engaging in intellectual debate.
