Why would Sai Baba choose an author who was admittedly mischievous, cynical, critical, and arrogant about his own knowledge to write his sacred biography?

Chapter 2 suggests that the author's initial negative qualities serve to highlight the transformative power of the Guru. The writer describes himself as initially "mischievous, talkative, cynical, and critical," with a "logic-driven mind." Sai Baba's instruction for him was to "dissolve his ego and surrender it at my feet." By choosing such a person, Sai Baba demonstrates that He is the true author, stating, "He is merely a pretext; I myself shall write my own story!" The author's personal journey from an arrogant intellectual to the surrendered devotee known as Hemadpant becomes a powerful testament within the story itself, illustrating the core teaching of ego dissolution as the path to divine assistance and grace.
