From the perspective of a skeptic like Boss Dharamsee, how did Sai Baba prove his sainthood and thereby grow his community of followers?

From the skeptical perspective of Boss Dharamsee, Sai Baba proved his sainthood not through grand pronouncements, but through a subtle, personal, and undeniable miracle that directly addressed his inner thoughts. As detailed in Chapter 35, Dharamsee silently disliked the seeded grapes Baba offered him and thought that a true saint should know his preference. Baba not only perceived this thought but then miraculously transformed the grapes into seedless ones as Dharamsee ate them. This astonished Dharamsee, who thought, "What a strange power! What is impossible for these saints?" This direct, personal experience shattered his "clinical scrutiny," causing his ego to vanish and be replaced by love and devotion, thus adding another follower to the community around Sai.
