How did Sai Baba respond to the internal doubts and skepticism of a visitor named Boss Dharamsee?

Chapter 35 illustrates how Baba masterfully handled Boss Dharamsee's skepticism. Dharamsee, who came with a "clinical scrutiny," was internally troubled when offered grapes with seeds, a variety he disliked. He silently questioned, "If he is a saint, how does he not know That I do not like these grapes?" In response to this unspoken challenge, Baba not only gave him more of those very grapes but then miraculously transformed them. When Dharamsee ate them, they were seedless. This act demonstrated Baba's omniscience and directly addressed the visitor's doubt, turning his skepticism into profound faith.
