The author of the Satcharitra expresses self-doubt about writing the book. According to Chapter 2, what are his reasons for hesitation, and what ultimately motivates him to proceed?

In Chapter 2, the author reveals his internal conflict and doubts about undertaking the task of writing Sai Baba's stories. He mentions his advanced age, having crossed sixty years, and feels his intellect is not sharp and feels empty. He fears that due to weakness, the effort might fail and amount to nothing more than empty talk. However, his primary motivation, as detailed in Chapter 2, is to collect Baba's stories for the sake of simple and loving devotees. He resolves to proceed because he believes the effort is a worthwhile spiritual goal dedicated to Sai's love, and he has faith that Baba himself will guide his hand, making him merely an instrument or a pen in the process.
