How did Sai Baba manage to change Boss Dharamsee's skeptical and critical attitude?

Sai Baba transformed Boss Dharamsee's skepticism through a direct and personal miracle that addressed his inner thoughts. As Chapter 35 recounts, Dharamsee was initially scrutinizing Baba, even thinking, "If he is a saint, how does he not know That I do not like these grapes?" In response to this internal challenge, Baba performed the leela of turning the seeded grapes into seedless ones in Dharamsee's mouth. This astonishing event caused Dharamsee's state of mind to be "stunned," his ego to drop away, and his clinical scrutiny to be replaced by a newfound love for the saint. His resolve to test Baba vanished, replaced by a firm determination to return to Shirdi.
