How does the story of Dharamsee demonstrate Sai Baba's omniscience?

The account of Boss Dharamsee in Chapter 35 serves as a profound testament to Sai Baba's omniscience, or his ability to know a person's innermost thoughts. Dharamsee was silently troubled; he disliked the seeded grapes, was concerned they were unwashed, and felt it improper to refuse them from a saint. He even had a specific thought: 'If he is a saint, how does he not know That I do not like these grapes?' As Chapter 35 recounts, Baba responded directly to this unspoken challenge. First, he gave Dharamsee more grapes, and then, he miraculously transformed them into the seedless variety Dharamsee preferred. Dharamsee himself realized this, thinking, 'Knowing the intent of my mind... Whatever Sai gives me, they turn out to be seedless and beneficial.' This direct and personal response to his hidden thoughts left no doubt about Baba's all-knowing nature.
