Can you explain the process of how Boss Dharamsee's doubt turned into faith?

The transformation of Boss Dharamsee from a skeptic to a devotee is beautifully narrated in Chapter 35. His journey began with a 'clinical' and curious mindset. His initial experience was one of internal conflict; he disliked the seeded, unwashed grapes Baba offered and doubted Baba's omniscience. This doubt intensified when Baba gave him even more grapes. The turning point came with an act of surrender. When Baba commanded, 'Throw them in and eat,' Dharamsee obeyed despite his reservations. The subsequent miracle—finding the grapes were seedless—was the catalyst for his change. As Chapter 35 recounts, 'All his ego dropped away, and love for the saint was born.' His skepticism was replaced by amazement and a firm determination to return to Shirdi.
