How does the author describe his role in writing this book and what were his personal doubts as mentioned in Chapter 2?

In Chapter 2, the author presents himself with great humility, stating he is merely an instrument for a divine purpose. He believes that Sai Baba himself is the true author, guiding his hand, and that he is "merely the owner in name." His motivation was to collect Baba's stories for simple and loving devotees. However, he also expresses significant personal doubts, mentioning that he had crossed sixty years of age, his intellect was not sharp, and he feared his effort might fail due to weakness. Despite these concerns, he proceeded with the effort for the love of Sai.
