How did Tarkhad's experience with the grapes differ from Dharamsee's, and what did this show?

The contrast between the experiences of Tarkhad and Boss Dharamsee is a key element of the story in Chapter 35. Both men were present and received grapes from the same distribution by Sai Baba. However, the miracle was exclusive to Dharamsee. After he was amazed to find his grapes were seedless, he asked Tarkhad about his. Tarkhad replied that his grapes did indeed have seeds, which greatly surprised Dharamsee. This difference demonstrated that the miracle was not a general occurrence but a highly personalized act by Baba, specifically tailored to address Dharamsee's internal doubts, his dislike for seeded grapes, and his unspoken challenge to Baba's sainthood. It showed that Baba interacts with each devotee according to their individual mind and needs.
