How did Sai Baba perceive and respond to the unspoken thoughts and feelings of his devotees?

Sai Baba possessed a profound ability to perceive and respond to the inner state of his devotees. Chapter 35 illustrates this perfectly with the story of Boss Dharamsee. While being offered grapes, Dharamsee was internally troubled because he disliked grapes with seeds and was concerned they were unwashed. As soon as this attitude of doubt arose in his mind, Baba gave him even more of them. The story in Chapter 35 explains that when Dharamsee finally ate the grapes on Baba's command, he found them to be seedless. Dharamsee then understood that Baba knew the 'intent of my mind' and had performed a miracle to directly address his unspoken reservations, turning his doubt into faith.
