How does one go from being a curious observer to a devoted follower of Sai Baba, based on the story of Boss Dharamsee?

The story of Boss Dharamsee in Chapter 35 provides a clear blueprint for the transformation from a curious observer to a devoted follower. Initially, Dharamsee arrived with a skeptical mindset, driven by 'clinical scrutiny' and curiosity about reported miracles. His transformation began with a test of faith and obedience. Despite his dislike for seeded grapes and his doctor's advice, he obeyed Baba’s command to eat them. This act of surrender, as described in the chapter, opened the door for a profound personal experience—the grapes becoming seedless in his mouth. This miracle directly addressed his inner doubts, causing his ego to dissolve completely. The text states, 'All his ego dropped away, and love for the saint was born,' replacing his skepticism with a 'firm determination' to return to Shirdi.
