What internal conflict did Boss Dharamsee experience when offered grapes, and how did this event ultimately change him?

Chapter 35 describes Boss Dharamsee's significant inner turmoil. He disliked grapes with seeds and was also concerned about eating them unwashed, as per his doctor's orders. This led him to mentally challenge Baba's powers, thinking that a true saint would be aware of his aversion. His mind was filled with various conflicting thoughts. The profound change occurred when he obeyed Baba's instruction to eat the grapes and discovered they were miraculously seedless. This event completely stunned him, causing 'all his ego' to drop away. His initial 'clinical scrutiny' was replaced by a deep love for Sai, and his resolve to return to Shirdi became a firm determination.
