What was the author Annasaheb's initial attitude towards Gurus, and what led to his transformation?

The preface reveals that Annasaheb did not initially possess any devotion or love for Gurus. As he wrote about himself in the third chapter, he used to believe that the practice of making a Guru was a fraud and felt there was no need for one, taking great pride in his own capabilities and doership. However, this perspective was completely shattered upon meeting Baba. The preface states in Chapter 0 that as soon as their eyes met and an internal spiritual witness was voiced, Annasaheb's pride crumbled. He became fully convinced that a Sadguru is essential to cross the ocean of life, and the subsequent writing of the Shri Sai Satcharita is described as the very fruit of Baba's grace upon him.
