How did Sai Baba handle skeptics who visited him, based on the account of Boss Dharamsee?

According to the narrative in Chapter 35, Sai Baba's method for dealing with skeptics was not through debate but through direct, personal experience. Boss Dharamsee arrived with a curious but detached attitude. Instead of lecturing him, Baba engineered a situation involving an offering of grapes. Baba was aware of Dharamsee's specific dislike for seeded grapes and his internal, skeptical thoughts. By miraculously changing the seeded grapes into seedless ones right as Dharamsee ate them, Baba addressed his doubt in a way that was impossible to deny. This experience caused Dharamsee's ego to drop away and be replaced with love, demonstrating that Baba leads people to the spiritual path by stimulating their disposition and providing personal, transformative moments.
