How did Sai Baba manage to change Boss Dharamsee's skeptical attitude into one of belief?

Sai Baba transformed Boss Dharamsee's skepticism into profound belief through a direct, personal experience that addressed his inner thoughts. Chapter 35 explains that Dharamsee, initially driven by curiosity about miracles, was internally critical. When offered grapes with seeds, he thought, "If he is a saint, how does he not know That I do not like these grapes?" Aware of this internal monologue, Baba not only insisted he eat the grapes but miraculously turned them seedless in his mouth. This act, as described in Chapter 35, demonstrated Baba's omniscience, causing Dharamsee's "state of mind" to be "stunned." His ego dropped away, and a deep love for Sai arose in his heart.
