What happened during Boss Dharamsee's first visit to Shirdi that challenged his skeptical mindset?

During his first visit, Boss Dharamsee arrived with a 'clinical scrutiny' and curiosity about miracles. As recounted in Chapter 35, he was offered grapes with seeds by Baba, a variety he disliked. Furthermore, his doctor had forbidden him to eat unwashed fruit. This created a conflict, and he mentally questioned Baba's sainthood for not knowing his aversion. Baba, sensing his thoughts, gave him more grapes and commanded him to eat them. When Dharamsee obeyed, he was astonished to find they were all seedless. This personal miracle shattered his ego and skepticism, replacing it with love for the saint.
