Why does the author feel that words are inadequate to describe Sai Baba's greatness in Chapter 49?

In Chapter 49, the author expresses the profound difficulty in capturing Sai Baba's true nature through language. He notes that even the Vedas and Puranas grew weary of praising the Sadguru. The author explains that Sai's Leela (divine play) is inexpressible and his art is inconceivable. He delves into a deeper philosophical explanation, mentioning that where even the transcendental (Para) and middle stages of speech (Pashyanti, Madhyama) fall silent, the fourth stage, the spoken word (Vaikhari), is utterly powerless. Therefore, as described in Chapter 49, silence is the truest praise, though the author's love for Sai compels him to write.
