What is the story of Sai Baba turning grapes with seeds into seedless ones?

The story from Chapter 35 recounts the visit of a skeptical man named Boss Dharamsee to Shirdi. A devotee named Kaka had brought grapes with seeds to offer Baba. When Baba offered these grapes to Dharamsee, he was internally conflicted because he disliked seeded grapes and had been advised not to eat unwashed fruit. He thought a true saint would know his preference. However, when Baba insisted he eat them, Dharamsee found they had miraculously become seedless. This personal experience, as detailed in Chapter 35, shattered his skepticism, caused his ego to vanish, and instantly filled his heart with love and devotion for Sai.
