Why does the author of the Satcharita feel that language is inadequate to describe Sai Baba?

The author expresses a profound sense of the inadequacy of language when trying to capture the greatness of the Sadguru. In Chapter 49, he begins by noting that even the ancient Vedas and Puranas grew weary in their attempts to praise the Guru, suggesting that silence is a more fitting tribute. He calls Sai's divine play (Leela) "inexpressible" and questions his ability to comprehend the "inconceivable art of the Unfathomable." He delves deeper by mentioning that even transcendental speech (Para) fails, and lower stages of speech like Pashyanti and Madhyama have no access, making the spoken word (Vaikhari) utterly incapable of describing Sai's true form.
