A friend of mine is very skeptical about spiritual matters but is curious about Sai Baba. How did Baba handle skeptics who came to see him?

The provided text from Chapter 35 illustrates how Baba masterfully handled skepticism. It tells the story of Boss Dharamsee, who arrived in Shirdi with a 'clinical interest' and a critical mind. When offered grapes with seeds, which he disliked, he internally questioned Baba's sainthood. In response, Baba not only knew Dharamsee's thoughts but gave him more grapes. Then, in a display of his divine power, the grapes Dharamsee ate became seedless. This personal miracle shattered his skepticism, causing his ego to drop away and be replaced with love and firm determination to return to Shirdi. This shows that Baba often works by providing a direct, personal experience that addresses an individual's specific doubts.
