How was Boss Dharamsee's skepticism transformed into devotion? What was the psychological turning point for him in Shirdi?

Boss Dharamsee's transformation from a skeptic to a devotee was a direct result of a personal miracle orchestrated by Sai Baba. According to Chapter 35, he arrived with a 'clinical scrutiny' and was immediately critical, silently judging Baba for offering him grapes with seeds, which he disliked. His turning point occurred when Baba, fully aware of his inner turmoil and thoughts, commanded him to eat the grapes. Upon doing so, Dharamsee was astonished to find they were seedless. This experience shattered his rationalist and ego-driven perspective. The text notes, 'His state of mind was stunned; he forgot his clinical scrutiny; All his ego dropped away, and love for the saint was born.' This direct, inexplicable event confirmed Baba knew his very thoughts, replacing his doubt with profound love.
