What personal motivations and self-doubts did the author express in Chapter 2 regarding his ability to undertake this project?

In Chapter 2, the author reveals a deep personal motivation, stating his mind became obsessed with collecting Baba's stories as a form of worship and for the benefit of devotees who hadn't seen Baba in person. However, he was also plagued by self-doubt. He mentions his advanced age of over sixty, a feeling that his intellect was not sharp, and a sense of physical weakness. He worried that his effort might fail and become nothing but "empty talk." Despite these fears, he resolved to proceed, concluding that even if it was just talk, it should be for Sai’s love to achieve a spiritual purpose.
