How does the author of the Sai Satcharitra describe his role in writing the book, and what personal doubts did he have?

In Chapter 2, the author portrays himself with great humility, insisting he is merely an instrument for a divine will. He states that Baba himself is guiding his hand, effectively making him the pen, while the author is only the "owner in name." Despite being motivated by a deep desire to collect Baba's stories for devotees, he reveals in this chapter that he harbored personal doubts. He discussed these concerns with Madhavrao (Shama), worrying that at over sixty years old, his intellect was no longer sharp and that physical weakness might cause the project to fail. He ultimately proceeded, viewing the effort as a worthwhile spiritual goal if done for the love of Sai.
