What personal doubts and overriding motivations did the author express in Chapter 2 regarding the task of writing the Sai Satcharitra?

In Chapter 2, the author confesses to having significant doubts about their ability to write this book. The author mentions being over sixty years old, feeling that their intellect was not sharp and was 'empty.' This led to a fear that the effort might fail and result in nothing but 'empty talk.' These doubts were shared with Madhavrao (Shama). However, the author's overriding motivation was a profound love for Sai. It was resolved that even if the writing turned out to be mere talk, it should be dedicated to Sai's love to achieve a spiritual purpose, as any other talk would be useless. This devotion, coupled with the desire to bring Baba's greatness to devotees who hadn't met him, provided the impetus to overcome these personal insecurities and begin the work.
