Why did Sai Baba give Boss Dharamsee more grapes when he knew Dharamsee disliked them?

Sai Baba's actions were a profound spiritual lesson designed to address Boss Dharamsee's ego and skepticism directly. Chapter 35 explains that as Dharamsee was silently judging Baba, thinking, 'If he is a saint, how does he not know I do not like these grapes?', Baba responded by giving him even more. This act was not to antagonize him, but to bring his internal resistance to a peak. It was a test of obedience and surrender. By then commanding him to eat and revealing the miracle of the seedless grapes, Baba demonstrated his omniscience in a way that was far more impactful than a simple conversation. This method, described in Chapter 35, was designed to make his 'ego drop away' and instill a deep, experience-based faith.
