I heard a story about Sai Baba turning grapes from seeded to seedless. Can you explain the details of this miracle and what it signifies?

The miracle of the grapes is a well-known leela detailed in Chapter 35. When a skeptical visitor, Boss Dharamsee, was given grapes with seeds, he was displeased and mentally challenged Sai Baba's omniscience. He thought, 'If he is a saint, how does he not know That I do not like these grapes?' In response to this internal doubt, Baba not only gave him more grapes but commanded him to eat them. When Dharamsee complied, he was amazed to find they had become seedless. This miracle signifies Baba's profound power; he knew Dharamsee's thoughts, addressed his skepticism directly, and demonstrated that what he gives is always 'beneficial.' The event completely transformed Dharamsee.
