According to Chapter 2, what is the author's role in writing the Sai Satcharitra, and how does he view his own capabilities?

Chapter 2 explains that the author sees himself as merely an instrument or an "ignorant person" through whom Sai Baba is authoring his own story. He humbly states, "Making me his pen, Baba himself will guide my hand. I am merely the owner in name; I only shape the letters." The author expresses significant self-doubt, mentioning that he has crossed sixty years of age and feels his intellect is not sharp. He worries that his weakness might cause the effort to fail, but he undertakes the task out of love for Sai, hoping to achieve a spiritual goal.
