How did the author describe his own personality before he understood the Satguru's greatness?

In Chapter 2, the author provides a very candid self-description of his character before his transformation. He states that he was initially "mischievous, talkative, cynical, and critical." He admits to having a "bad intellect and a logic-driven mind" and being "always proud of his own wisdom." Furthermore, he confesses that he was prone to argumentation and had an arrogance about his knowledge, knowing nothing of the true greatness of a Satguru. This honest portrayal of his former self serves to highlight the profound change he underwent through Sai Baba's grace.
