Why does the author feel that human language is incapable of describing Sai Baba's true nature?

The author expresses a profound sense of the limitations of language when trying to describe the Sadguru. Chapter 49 explains that Sai's Leela is "inexpressible" and His art is "inconceivable." The author supports this by referencing the Hindu philosophy of speech, noting that Sai's greatness exists in a realm where even the highest, transcendental form of speech (Para) returns, and where the middle stages (Pashyanti, Madhyama) cannot find expression. Given this, he questions what the lowest form of speech, the spoken word (Vaikhari), could possibly accomplish in describing the Unfathomable, reinforcing the idea that Sai's true form is beyond human comprehension and description.
