How does the author describe the fundamental challenge and paradox of trying to write the biography of a Saint?

The author grapples with the profound difficulty of his task, highlighting a central paradox. In Chapter 2, he states that 'One must first become a Saint to truly know a Saint.' This reveals his feeling of inadequacy, as he questions how he can possibly describe the inner world of a Saint without error when he cannot even fully recognize his own inner self. He uses powerful metaphors, suggesting that measuring a Saint's worth is as impossible as measuring the water of the seven seas or wrapping the sky. He even notes that the four Vedas fell silent when trying to define the Divine Form, emphasizing the monumental and perhaps impossible nature of his endeavor.
