How does the author express his personal humility and sense of inadequacy in the face of writing about Sai Baba?

The author repeatedly expresses profound humility regarding his qualifications for writing about Sai Baba. In Chapter 2, he refers to himself as a 'lowly person' and acknowledges his own ignorance. He compares his daring effort to a 'small mouth taking a big bite' and prays that he is not ridiculed for the attempt. This sense of inadequacy is rooted in his belief that a Saint's glory is immeasurable and that he cannot truly understand Baba's nature. Despite feeling unqualified, he admits that the desire to sing Baba's praises is an 'uncontrollable' wave, which he ultimately attributes not to his own merit but to Baba's grace and inspiration.
