According to the author in Chapter 2, what is his role in writing the Satcharitra, and what is his motivation?

In Chapter 2, the author describes his role with great humility, stating he is merely an instrument for Sai Baba. He famously says, 'Making me his pen, Baba himself will guide my hand. I am merely the owner in name; I only shape the letters.' This illustrates his belief that the work is divinely inspired. His motivation stems from a deep desire to collect and share Baba's stories, which he calls 'leelas,' for the benefit of devotees, especially those who never saw Baba in person. He mentions his mind became obsessed with this task and that even though he is over sixty and feels his intellect is not sharp, he undertakes this effort for the love of Sai.
