How did Sai Baba respond to Dharamsee's skepticism about him being a real saint?

Sai Baba responded to Boss Dharamsee's skepticism not with words, but with a direct and personal miracle. Chapter 35 recounts how Dharamsee, upon receiving grapes with seeds, thought to himself, "If he is a saint, how does he not know That I do not like these grapes?" Rather than admonishing him, Baba, being aware of this internal doubt, gave him even more of the grapes. When Dharamsee hesitated, Baba commanded him, "Throw them in and eat." Upon obeying, Dharamsee found the grapes were now seedless. This act directly addressed his specific dislike and doubt, demonstrating Baba's omniscience and power. The result was the complete dissolution of Dharamsee's ego and the birth of deep love and faith in the saint.
