Can you describe the transformation of Annasaheb's belief in Gurus as detailed in the preface?

The preface provides a compelling account of Annasaheb's transformation regarding his belief in Gurus. According to the information in Chapter 0, Annasaheb initially had no Guru devotion at all. He even used to believe that "making a Guru was a fraud" and took great pride in his own doership, feeling no need for a spiritual guide. However, this perspective was completely overturned upon meeting Baba. The text describes a pivotal moment when "his eyes met Baba's," an internal spiritual witness was voiced, and his pride was "completely shattered." This experience led him to become fully convinced that one cannot cross the ocean of life without a Sadguru.
