What personal motivations and self-doubts does the author reveal in Chapter 2 regarding his project to write about Sai Baba's life?

In Chapter 2, the author explains his motivation stems from a deep desire to collect Sai Baba's stories for the benefit of "simple and loving devotees," especially those who never had the chance to see Baba in person. He hopes that hearing about Baba's greatness will bring them merit and peace. However, he also expresses significant self-doubt, mentioning to Madhavrao (Shama) his fear of failure. Being over sixty years old, he feels his intellect is not sharp and that weakness might prevent him from completing the immense task. Despite these concerns, he concludes that even the effort itself is a worthy spiritual goal undertaken for Sai's love.
