How does Sai Baba address skepticism, as shown in the story of Boss Dharamsee and the grapes?

The story of Boss Dharamsee in Chapter 35 illustrates that Sai Baba addresses skepticism not through argument, but through direct, personal experience. When Dharamsee silently questioned Baba's sainthood for offering him grapes he disliked, Baba's response was to give him even more. This shows Baba's awareness of his innermost thoughts. The subsequent miracle, where the grapes with seeds became seedless only for him, was a tailored response to his specific doubt. This method bypasses the rational, skeptical mind by providing undeniable proof that is personal and profound, causing the individual's ego to drop away and be replaced by faith and love.
