I'm skeptical about the grape incident. How did Sai Baba know Boss Dharamsee's thoughts and preferences?

The account in Chapter 35 directly addresses this skepticism by detailing Dharamsee's internal thoughts. As Baba offered him the grapes, Dharamsee thought to himself, 'If he is a saint, how does he not know That I do not like these grapes?' Immediately following this thought, Baba gave him even more grapes, indicating a direct awareness of his mental state. The miracle was confirmed when Dharamsee found his grapes were seedless, while Babasaheb Tarkhad, sitting nearby, confirmed his own grapes from the same bunch had seeds. This demonstrated that the event was not a coincidence but a deliberate act by Baba to show he knew the 'intent of my mind,' as Dharamsee later realized.
