What is the significance of surrendering one's ego when approaching Sai Baba, as shown in the story of the grapes?

The story of Boss Dharamsee in Chapter 35 is a profound lesson on the importance of surrendering the ego. Dharamsee initially approached Baba with his ego intact—full of personal dislikes, skepticism, and 'clinical scrutiny.' He judged the situation based on his preferences for seedless grapes and his doctor's advice. The text notes that trying to understand Baba's ways leads to misfortune, and only by 'becoming egoless and rolling at his feet' can one find happiness. The turning point for Dharamsee came when he obeyed Baba's command to eat, against his own judgment. At that moment of surrender, his ego was broken, and he was able to experience Baba's divine power. As the text states, 'All his ego dropped away, and love for the saint was born.'
