Can you describe the incident with Boss Dharamsee and the grapes, and how it revealed Sai Baba's divine knowledge?

Boss Dharamsee, who was initially skeptical and visiting with a "clinical scrutiny," was offered grapes by Sai Baba. As described in Chapter 35, Dharamsee internally disliked these grapes because they had seeds and were unwashed. He even questioned Baba's sainthood in his mind, wondering why a true saint wouldn't know his preference. In response to this unspoken thought, Baba gave him even more grapes and instructed him to eat them. When Dharamsee finally did, he was astonished to find they had become seedless. This miracle directly addressed his inner doubt, causing his ego to drop away and be replaced by love and reverence for Baba's omniscience.
