What insight does the text give into the author Annasaheb's personal spiritual state before writing the book?

The preface provides a fascinating insight into the author's journey. While the Shri Sai Satcharita is a profound work of devotion, it is noted in chapter 0 that its author, Annasaheb, did not begin with this deep-seated faith. Based on an account Annasaheb wrote about himself in the third chapter, which is referenced in the preface, he initially had no Guru devotion or love for the Guru at all. This detail is significant because it suggests a personal transformation, indicating that the creation of this spiritual book was intertwined with the author's own evolving faith, likely fueled by the very Guru's grace he came to extol in his writing.
