Can you please recount the story about Sai Baba and the grapes? What was the miracle that occurred?

Certainly. The story of the grapes is a well-known leela from Chapter 35. A devotee named Kaka brought grapes with seeds as an offering to Baba. When Baba began distributing them, a visitor named Boss Dharamsee, who disliked seeded grapes, received some. He was conflicted and internally questioned Baba's sainthood for not knowing his preference. As described in Chapter 35, Baba, aware of his inner turmoil, gave him even more grapes and commanded, 'Throw them in and eat.' When Dharamsee obeyed, he was astonished to discover that the grapes in his mouth were completely seedless. His amazement deepened when he asked another devotee, Babasaheb Tarkhad, who confirmed that the grapes he had received still had their seeds. This miracle demonstrated Baba's omniscience and power, instantly transforming Dharamsee's skepticism into profound love and devotion.
