How does the story of Boss Dharamsee prove that Sai Baba knew what was in people's minds?

The account of Boss Dharamsee in Chapter 35 provides a compelling example of Sai Baba's omniscience. Dharamsee was silently thinking, "If he is a saint, how does he not know That I do not like these grapes? Why does he force them upon me?" In direct response to this unspoken thought, Baba immediately gave him even more of the grapes. The ultimate proof came when Baba, knowing Dharamsee's precise dislike, transformed the seeded grapes into seedless ones the moment Dharamsee ate them, demonstrating that Baba was intimately aware of and responding to his innermost thoughts and feelings.
