What was the miracle of the grapes, and how did its perception differ between Boss Dharamsee and Babasaheb Tarkhad?

The miracle of the grapes, described in Chapter 35, was a personal and transformative event for Boss Dharamsee. After being given grapes with seeds, which he disliked, he was commanded by Sai Baba to eat them. Upon doing so, he 'found they were all seedless and was greatly surprised.' This experience shattered his skepticism. The personal nature of this miracle is highlighted by the contrast with another devotee, Babasaheb Tarkhad. When Dharamsee asked him about his grapes, Tarkhad confirmed that his still had seeds. This confirmation, as Chapter 35 notes, made Dharamsee 'extremely surprised in his heart,' reinforcing that Baba had performed a miracle specifically for him, addressing his unique internal state of doubt and transforming it into unwavering faith.
