How did Sai Baba handle skeptics who visited him, and what methods did he use to guide them to a spiritual path?

The provided text illustrates how Sai Baba masterfully handled skepticism with profound insight and tailored experiences. In Chapter 35, a man named Boss Dharamsee visited Shirdi with a 'clinical scrutiny,' doubting Baba's sainthood when offered grapes with seeds, a variety he disliked. Dharamsee thought to himself, 'If he is a saint, how does he not know that I do not like these grapes?' In response, Baba, fully aware of his inner thoughts, gave him even more. When Dharamsee was commanded to eat them, the seeded grapes miraculously became seedless. This personal miracle stunned Dharamsee, causing his ego to drop away and a deep love for the saint to be born, demonstrating how Baba stimulates a person's disposition to lead them toward spirituality.
