Chapter 49 mentions different stages of speech like Para and Vaikhari. How does the author relate these concepts to the challenge of describing the Sadguru?

In Chapter 49, the author grapples with the inadequacy of language to capture the Sadguru's greatness. He references the stages of speech to illustrate this challenge, noting that where the transcendental speech (Para) returns and the middle stages (Pashyanti, Madhyama) are not mentioned, the fourth stage, the spoken word (Vaikhari), is utterly powerless. This signifies that the Sadguru's true nature is beyond the highest forms of intuitive expression, let alone the spoken word. Despite knowing this limitation completely, the author's mind cannot remain still, highlighting the devotee's internal conflict between the awareness of the Guru's ineffable nature and the overwhelming love that compels them to try and describe it.
