What does the preface of the book reveal about the spiritual background of its author, Annasaheb?

The preface, drawing from information in Chapter 0, provides a fascinating glimpse into the author's initial state of mind. It reveals that there is no clear evidence of a pre-existing tradition of Guru devotion in Annasaheb's family. More pointedly, Chapter 0 states that based on Annasaheb's own account in the third chapter of the work, he initially had no Guru devotion or love for the Guru at all. This suggests his profound devotion was a developed quality that blossomed over time rather than an inherent one from his upbringing.
