How does the author of the Shri Sai Satcharitra view his own qualifications for writing about a great Saint?

In Chapter 2, the author expresses profound humility and feels entirely unqualified for the task. He questions how he can possibly describe the inner mind of a Saint when he cannot even fully understand his own inner self. He posits that one must first become a Saint to truly know a Saint. He describes his effort as a 'daring' one, like a 'small mouth taking a big bite,' and feels the worth of a Saint is immeasurable, unlike the seas which can be measured or the sky which can be wrapped. This deep sense of inadequacy is a recurring theme in the chapter.
