I have doubts about spirituality. How did Sai Baba handle people who were skeptical of him?

The story of Boss Dharamsee provides a compelling example of how Baba dealt with skepticism. Dharamsee arrived in Shirdi with a 'clinical scrutiny' and was doubtful. As detailed in Chapter 35, he internally questioned Baba's sainthood when offered grapes with seeds, a variety he disliked. He thought, 'If he is a saint, how does he not know That I do not like these grapes?' Instead of arguing, Baba engineered a personal miracle. Upon being commanded to eat more grapes, Dharamsee found they had become seedless. This direct, personal proof was so powerful that 'All his ego dropped away, and love for the saint was born,' demonstrating Baba's method of using tailored experiences over words to dissolve doubt.
