Based on the story of Dharamsee, what was Sai Baba's method for turning a curious visitor into a devoted follower?

Based on the account in Chapter 35, Sai Baba's method for converting curiosity into devotion involved a personalized demonstration of his divine knowledge. He didn't use generic teachings for the curious Boss Dharamsee. Instead, he zeroed in on Dharamsee's specific, unspoken dislike for seeded grapes. By knowing this and then miraculously altering the grapes to be seedless, Baba provided an irrefutable, personal proof of his sainthood. This experience, as Chapter 35 narrates, dismantled Dharamsee's "clinical scrutiny" and ego, replacing them with love and a "firm determination" to return. This suggests Baba's method was to create a unique experience that directly answered the individual's deepest doubts.
