Why does the author find it so difficult to describe Sai Baba's greatness, and what does he say about the limits of speech?

The author expresses immense difficulty in capturing Sai Baba's greatness because he believes it is beyond the capacity of human language. Chapter 49 describes Sai's divine play (Leela) as "inexpressible" and his nature as "unfathomable." To illustrate this, the author refers to the four stages of speech in Indian philosophy. He notes that where the transcendental speech (Para) must return and the middle stages (Pashyanti and Madhyama) find no entry, the fourth stage, the spoken word (Vaikhari), is utterly powerless. This signifies that Sai's true essence cannot be comprehended or articulated through ordinary means, only experienced through grace and surrender.
