How does the author use the limits of language to explain the greatness of the Sadguru in Chapter 49?

The author of the Sai Satcharitra expresses in Chapter 49 that the Sadguru's greatness is fundamentally beyond human description. He states that Sai's Leela is "inexpressible" and that his own speech cannot capture the "inconceivable art of the Unfathomable." To illustrate this, he references the Vedic concept of the four levels of speech. He notes that where the transcendental speech (Para) returns defeated, and the inner stages of speech (Pashyanti and Madhyama) do not even venture, the fourth and most external form, the spoken word (Vaikhari), is utterly powerless. This highlights the profound idea that the Sadguru's true nature transcends the very structure of language and comprehension.
