Could you recount the story of Dharamsee Jethabhai and his experience with the grapes in Shirdi?

Certainly. The story, found in Chapter 35, illustrates how Sai Baba worked on an individual's heart. Boss Dharamsee Jethabhai visited Shirdi with a curious but critical mind. During his darshan, another devotee offered Baba grapes that had seeds, a variety Dharamsee strongly disliked. Baba began distributing these grapes, and despite Dharamsee's internal reluctance and thoughts about how a true saint should know his preference, Baba gave him even more. Troubled, Dharamsee held them until Baba commanded, 'Eat them up.' Upon obeying, he was astonished to find the grapes were completely seedless. This personal miracle shattered his skepticism, and he was filled with amazement and love for Sai, realizing the saint knew his mind and could transform reality for his devotee's benefit.
