Why does the author of Chapter 49 feel that language is inadequate to describe Sai Baba?

The author expresses the profound inadequacy of language in Chapter 49 by stating that Sai's divine Leela (play) is inexpressible and questions how one can comprehend the "inconceivable art of the Unfathomable." He references the different stages of speech in Vedic philosophy, noting that where the transcendental speech (Para) returns and the middle stages (Pashyanti, Madhyama) are silent, the fourth stage, the spoken word (Vaikhari), is utterly powerless. This illustrates his belief that the Guru's greatness exists beyond the limits of human expression and comprehension.
