How did Sai Baba address the skepticism and ego of a devotee like Boss Dharamsee?

Sai Baba addressed Boss Dharamsee's skepticism not through argument, but through a direct, personal experience designed to dismantle his ego. As detailed in Chapter 35, Dharamsee arrived with a 'clinical scrutiny' and was immediately challenged when Baba offered him grapes he disliked. His ego flared, causing him to think, 'If he is a saint, how does he not know That I do not like these grapes?' Instead of placating him, Baba gave him even more. The true lesson came when Dharamsee finally surrendered and obeyed Baba's command to eat them, only to find they had become seedless. This act demonstrated that Baba knew his innermost thoughts and that surrender to His will leads to beneficial outcomes, causing Dharamsee's ego to drop away and be replaced by love.
