The text contrasts the author being a 'pretext' with his former argumentative self. Explain this contrast and what happens when one's ego is fully dissolved, according to Sai Baba.

The contrast is between the author's original state and the state required for the divine work. Chapter 2 describes the author as initially being proud, cynical, and argumentative. However, Sai Baba states that the author is 'merely a pretext' and that He Himself would write the story. This is contingent on the author dissolving his ego and surrendering at Sai's feet. According to Sai Baba, when the ego is dissolved and no trace of it remains, 'I myself shall enter with 'I-ness' and write with my own hand,' providing full assistance not just for the story but in all ways. This highlights the complete opposition between an ego-driven, argumentative mind and a surrendered vessel for divine action.
