How does the author of Sai Satcharitra describe his role in writing the book and what was his personal motivation?

In Chapter 2, the author expresses deep humility, viewing himself not as the true writer but as an instrument for a higher power. He states, "Making me his pen, Baba himself will guide my hand," clarifying that he is merely the owner in name. His motivation, as described in Chapter 2, came from a desire to collect Baba's stories for the sake of simple and loving devotees, especially those who had not seen Baba in person. Despite personal doubts about his capabilities due to his advanced age of over sixty, he undertook the effort as a form of worship to achieve a spiritual goal.
