How did the author of the Satcharitra come to understand the importance of Shraddha and Saburi?

The author, Hemadpant, learned the importance of Shraddha (faith) and Saburi (patience) through a humbling personal lesson from Sai. In Chapter 2, he recounts receiving a name that was like a "speech-arrow" meant to destroy his pride in debating. This experience made him realize that arguing is a harmful trait. He contemplated how even divine incarnations like Rama and Krishna submitted to their Gurus. This led him to the conclusion that without a Guru there is no spiritual goal, and more importantly, that without faith and patience, not even a fraction of that goal can be attained.
