What exactly was the miracle that happened to Boss Dharamsee with the grapes?

The miracle experienced by Boss Dharamsee involved the transformation of grapes he received from Sai Baba. According to chapter 35, Dharamsee disliked grapes with seeds and was troubled when Baba kept giving them to him. Despite his reluctance, Baba instructed him, "Throw them in and eat." When Dharamsee obeyed and put the grapes in his mouth, he was astonished to find they were all seedless. This personal miracle, tailored to his specific dislike, stunned him and made him realize the immense and subtle power of the saint, who could alter reality based on the devotee's innermost thoughts.
