Can you explain the role of a Guru in developing devotion, based on Annasaheb's experience?

Annasaheb's journey provides a powerful example of a Guru's transformative role. The preface, referencing an account from Chapter 3, explains that Annasaheb initially had no Guru devotion at all. He used to think making a Guru was a fraud and was proud of his own self-reliance. However, as detailed in Chapter 0, the moment his eyes met Baba's, his pride was completely shattered. This encounter led him to become fully convinced that a Sadguru is essential for crossing the 'ocean of life.' This profound shift from skepticism to conviction demonstrates how a Guru's grace can awaken and nurture devotion in a person.
