What was the miracle involving the grapes, and how did it transform Boss Dharamsee's attitude towards Sai?

The miracle occurred when Boss Dharamsee, who intensely disliked grapes with seeds, was given a handful by Sai Baba. After struggling with his doubt, Baba commanded him to "Throw them in and eat." Upon obeying, Dharamsee was amazed to discover the grapes were completely seedless. As described in Chapter 35, this experience shattered his skepticism. He thought, "What a strange power! What is impossible for these saints?" The text states that his state of mind was stunned, his ego dropped away entirely, and a profound love for the saint was born in his heart, replacing his previous clinical scrutiny.
